RAL1000 green beige electrostatic thermoset powder coating for outdoor metal iron
We all know that thermoset is the most common powder coating considered to be thin but hard.
Thermoset powder coating and thermoplastic powders, they have different features to suit different applications. Here we list a detail comparison that may help you know more about these two powder coatings.
Structure
Thermoplastic powder coating features longer chain molecules; in
contrast, thermoset powder coating starts with short molecules
which are cross-linked together during the curing process to form a
permanent matrix based on an irreversible chemical reaction. And
the structure differences determine the different properties of
these two powder coatings.
Weight
Most thermoplastic powder coatings are in lighter weight so that
fewer pounds of thermoplastic powders are used to achieve the same
thickness of thermoset coating.
Thickness
Generally, thermoset powder coating is considered as a thin, rigid
and tightly cross-linked coating; while thermoplastic powder
coating is thicker than thermoset - about 8 mils to 100 mils in
thickness for specific requirements.
Flexibility & impact resistance
High hardness enables the thermoset powder coating extremely
resistant against scratch and mar. Thermoplastic type is more
closely associated with plastic film featuring high flexibility,
ductility and high percent elongation which impart high impact
resistance to the coating, yet lower scratch and mar resistance.
But our Adherest polyethylene powder coating breaks this limitation
- that is because its high adhesion ensures the coating tightly
adheres to the parts regardless of the rough scratch and mar.
Recyclability
Both thermoplastic and thermoset powder coatings are dry
particulates that will melt and flow to from a smooth coating.
However, thermoplastic powder coating is recyclable as they will
soften and flow again if reheated at a temperature about 300°F. And
thermoset powder coating is irreversible after the initial cure and
cooling. Thus, they are not recyclable.

Jinhu Color Powder Coating Co.Ltd
Jinhu Color Powder Coating Co.,Ltd with brand FEIHONG founded in 1993,is a rapid growing enterprise who integrate the production and marketing of thermoset powder coating.After 28 years' effort and development,now we have become one of the leading powder coating,powder paint manufactures and suppliers in China.
We are always keeping kind relationship with our distributors and end users around the world,and enjoy high reputation in powder coating industry domestically and internationally.
Feihong factory focus on formulating kinds of electrostatic powder coatings,which include epoxy,epoxy polyester (Hybrid),pure polyester,polyurethane powder coating for indoor,outdoor application.With advanced production lines and professional technology,besides the regular powder paints,we do very well in bonding powder paint,metallic powder paint and textured powder paint,which are widely used in metal surface coating for decorative and protective purpose.The products are successfully exported to more than 48 countries.
But Feihong have never stop going forward,in order to control the cost and supply competitive price,better in-time service for our European customers,in 2017 we built another factory in Europe,which is for producing powder coating and exibiting the color sample panels to customers nearby.
For meeting customers' specific color requirements,color matching and tailor-made service are provided before placing bulk order.
We take "Quality, Service, Innovation, Efficiency" as a market philosophy, and introduce the first-class equipment, advanced testing device to ensure output prenium products, and serve all customers with best and instant service .
