Is plastic powder coating toxic? The plastic powder is charged by a high-voltage electrostatic device, and under the action of an electric field, the paint is sprayed onto the surface of the workpiece, and the powder is uniformly adsorbed on the surface of the workpiece to form a powder coating; and the powder coating is baked at a high temperature. When the leveling is solidified, the plastic particles will melt into a layer of dense final protective coating; the film is firmly attached to the surface of the workpiece, and the sprayed product is mostly used for indoor use, and the paint film has a flat or matte effect. The spray powder mainly includes acrylic powder, polyester powder and the like.
Acrylic powder coatings have excellent decorative, weathering, and anti-contamination properties with high surface hardness. Good flexibility. However, the price is high and the corrosion resistance is poor. Therefore, European countries generally use pure polyester powder (containing carboxyl resin, cured with TGIC); (hydroxyl-containing polyester resin is cured with isocyanate) as a weatherable powder coating. Plastic powder coating
A powder coating made of a hydroxy polyester resin which has excellent weather resistance and is generally called a weather resistant powder coating. Applied to aluminum extrusion materials for doors and windows, road marking piles, automotive industry, transportation equipment: accessories and wheels for automobiles and motorcycles, bicycle body and road isolation fences, air conditioner casings and gas stove plates, garden appliances, handrails And fences, agricultural equipment and utility poles.
Because the plastic powder coating will contain the curing agent TGIC. TGIC is triglycidyl isocyanurate, a heterocyclic polyepoxide with excellent heat resistance, weather resistance, adhesion and excellent high temperature properties. It is mainly used as a curing agent for carboxyl-containing polyester and carboxyl acrylic resin powder coatings. It is toxic and has an effect on the reproductive system. Therefore, when using plastic powder coating, it should also be protected.
Today, the small series of safety nets are toxic to plastic powder coatings. A brief introduction to how to properly select coatings and waterproof coatings during renovation, please learn more about home decoration and hope to help you.
