Powder polyester resins is a free-flowing, dried powder you spray onto a material using a spray gun. This powder is electrostatically charged to ensure the powder sticks to the workpiece while it’s connected to the ground circuit. For this reason, powder polyester resinss are mainly suitable for conductive materials like metal.
Advantages of Powder Polyester Resins
Weather resistant
Powder polyester resins have a great resistance to heat and ultraviolet radiation, making them an excellent choice for harsh outdoor conditions. For this reason, they’re often applied to outdoor products like fences or metal and other heat-sensitive items.
Environmentally friendly
If you are looking for a more sustainable solution, many powder polyester resins are environmentally friendly because you can carry out this process without releasing any toxic emissions or waste. This also reduces the need for an intensive waste disposal process. While TGIC-type powder polyester resins may release volatile organic compounds with excessive exposure to heat, you can avoid emitting harmful substances with most other polyester powders.
Economical
Since these coatings last longer and the process is fast, powder polyester resins can be particularly beneficial for manufacturers who carry out bulk productions. With powder polyester resins, coating materials in bulk can make operational costs more economically feasible.
Chemical and corrosion resistant
With powder polyester resins, you may be able to avoid damage from chemicals and corrosion, especially against alkalis and acids. Workpieces with powder polyester resins will often work better in liquid mediums with different chemical concentrations than other coatings that may corrode in this condition.
Efficient for use
Powder polyester resins is a great option for bulk production because the process of applying it is more efficient than with other traditional paints. It also allows for less waste since the coating particles provide maximum adhesion, and you can extract any unused or extra coating in the air with a chamber and reuse it.
Everything You Need for Powder Polyester Resins
Powder polyester resins consist of the following materials: Resins, hardeners, additives, fillers and pigments. allnex as a leading global supplier, offers an advanced portfolio of polyester resins, several hardeners and selected additives.
Resins
Predominantly determine coating performance like flexibility, toughness, chemical- and corrosion resistance. The resin design defines the outdoor durability, the curing schedule, as well as the physical and chemical stability of correspondent powder coatings. Especially our CRYLCOAT® 2441-2, CRYLCOAT® 2618-3, and CRYLCOAT® 4488-0 resins excel in outdoor durability.
Hardeners
Undergo chemical conversion during the curing process with functional groups of polyester resins providing a cross-linked polymer network. The allnex line of poly-anhydride hardeners like ADDITOL® P 791 and BECKOPOX™ EH 694 serve as specialties in specific coatings segments.
Additives
Every powder coatings formulation requires the presence of certain additives to optimize characteristics such as: flow and leveling, to avoid film defects like craters and fish-eyes, triggering reactivity and chargeability for tribo applications. Some additives are essential to enhance smoothness and flexibility of coatings or to enable formulation of effect coatings leading to wrinkle finishes.
Powder polyester resins is made using various raw ingredients, such as resins, pigments, matting agents, flow agents, curing agents and waxes, to name a few. The manufacturing process for powder polyester resinss generally involves five primary steps:
• Dry blending all the raw ingredients.
• Passing the ingredients through an extruder at an elevated temperature to melt the resins, mill the pigments and attain a homogeneous mix.
• Rapidly cooling the extrudate.
• Milling the flakes of the extrudate to the final size in a multi-stage process.
• Removing any oversized and undersized particles.
What Industries and Products Are powder polyester resins Used For?
You can use powder polyester resinss for a variety of industries and products. The most common materials used with this coating include metal surfaces like aluminum and steel. Here are a few of the industries that use powder polyester resinss most:
◆ Automotive industry: The automotive industry might use this coating for an intermediate finish on wheel finishing, external door surfaces and under-the-hood finishing.
◆ Furniture industry: Furniture manufacturing companies especially like to use this coating on outdoor furniture like tables, chairs, cages and metal benches.
◆ Architectural industry: Powder polyester resins’s resistance to fading makes it a notable option for fencing, guard rails, window frames and stadium seating.
◆ Home appliance industry: Appliance companies will often use this powder polyester resins on items like food utensils, refrigerators, microwave ovens and washing machines.
◆ Electronics industry: The electronics industry will mostly use this coating on external frames and surfaces of electronic appliances such as pumps and blenders for extra protection.
What Are The Storage Requirements For Powdered Polyester Resins?
Storage environment
Powdered polyester resins should be stored in dry, cool and ventilated warehouses, avoiding direct sunlight and high temperature environment. The storage temperature should be kept between 15-25 degrees Celsius and the relative humidity should be kept between 50-70%.
Packaging
The packaging of powder polyester resin should be made of materials with good sealing and corrosion resistance to prevent air pollution and chemical corrosion. Packaging materials should be lined with plastic bags and encapsulated in cardboard or plastic drums with a net weight of 25kg or 50kg per drum.
Storage time
Powdered polyester resins should preferably not be stored for more than 6 months. If the storage time is too long, it may lose some of its properties due to external factors and eventually lose its value.
Safety measures
During storage, any kind of mechanical vibration and friction should be avoided to avoid affecting the performance and service life of the resin. The storage container should be placed in a stable position and should not directly touch the ground.
Precautions for use
Before use, ensure that the powder polyester resin is kept in dry, ventilated and cool storage conditions, avoiding direct sunlight and rain. Avoid contamination of skin and eyes. If contaminated inadvertently, rinse with plenty of water.
Surface quality
One of the main reasons why polyester resin has become such a popular choice for powder coating is because of the high-quality surface finish it provides. Unlike traditional liquid-based coatings, polyester resin for powder coating creates a smooth, uniform surface that is free from brush or roller marks. This is because the powder is applied using an electrostatic spray gun that creates an even coat over the entire surface.
Environmental benefits
Another major benefit of using polyester resin for powder coating is that it is much more environmentally friendly than traditional coatings. Traditional liquid-based coatings contain volatile organic compounds (VOCs) which can be harmful to the environment and human health. Polyester resin for powder coating, on the other hand, is solvent-free and produces no emissions during the application process. This makes it a much more eco-friendly choice.
Weather resistance
Polyester resin for powder coating is also highly resistant to weathering. It can withstand exposure to UV radiation, extreme temperatures, and moisture without losing its color or luster. This makes it an ideal choice for outdoor applications such as garden furniture, fencing, and automotive parts.
Durability
Another major advantage of using polyester resin for powder coating is its durability. Due to its strong bond to the substrate, it is highly resistant to chipping, scratching, and wear. This makes it an ideal choice for high-traffic areas such as factories, hospitals, and schools.
The Application of Polyester Resin in Powder Coating
Polyester resin is a widely used material in powder coating due to its unique properties. Powder coating is a type of coating that is applied to metal surfaces and cured under heat to form a smooth, hard and durable finish. Polyester resin plays a vital role in powder coating as it acts as a binder to hold the pigments and additives together in the powder mix.
One of the main advantages of polyester resin in powder coatings is its excellent adhesion properties. Polyester resins form a strong chemical bond with metal surfaces, making them ideal for use in harsh environments. They can also be used to improve the corrosion resistance of metal surfaces as they are resistant to rust and oxidation.
Another key feature of polyester resins in powder coatings is their versatility. These resins can be used to create a wide range of colours, finishes and textures, making them an ideal choice for a variety of applications. The addition of pigments and other additives can produce a range of finishes including gloss, semi-gloss and matt.
Polyester resins for powder coatings also offer excellent mechanical strength and durability. They are resistant to chipping, scratching and other forms of physical damage, making them ideal for use in high-traffic areas. They also offer excellent UV resistance, ensuring that colours remain vibrant and do not fade over time.
Finally, polyester resins for powder coatings are very cost effective and environmentally friendly. They are easy to apply and their high solids content means less material is required to achieve the desired finish. They also produce less waste than traditional liquid coatings, reducing both disposal costs and environmental impact.
Wear protective equipment: Protective equipment such as gloves, masks and goggles must be worn during use to avoid direct contact with the polyester resin powder.
Avoid inhalation of dust: Powdered polyester resin produces dust during processing and inhalation of excessive amounts of dust may adversely affect the respiratory system, causing symptoms such as coughing, shortness of breath and difficulty in breathing. Therefore, good ventilation should be maintained to avoid inhalation of dust.
Avoid skin and eye contact: If polyester resin comes into contact with skin or eyes, it will cause irritation and allergic reaction. Therefore, direct skin contact should be avoided during handling, and if contact is made, the skin should be washed immediately with soap and water, and medical attention should be sought in serious cases.
Correct storage: Polyester resin should be stored in a dry, ventilated and light-proof place, away from moisture and direct sunlight.
Read safety instructions: Read the relevant safety instructions carefully before use and follow the operating procedures, it is strictly forbidden to mix polyester resin with other chemicals unless under the guidance of professional personnel.
