Modified epoxy coatings are resistant to high temperature and pollution

Researchers from Ningbo Key Laboratory of Marine Protection Materials and Engineering Technology have successfully prepared a variety of modified powder coatings, and have recently obtained the national invention patent authorization
.
The patent provides a method and technology for preparing a high temperature resistant and
anti-fouling epoxy resin powder coating.

Compared with existing technologies, fluorosilicon-modified epoxy powder coatings improve the high temperature and anti-fouling properties of the coating, and can be used
in environments up to 500°C.
In addition, the coating preparation process is simple, the cost is low, and the coating appearance is bright, flat and can be thinly coated
.

It is understood that ordinary epoxy resin powder coatings are easily stained by dust and oil due to electrostatic action, which affects the decorative properties
of the coating.
In addition, under high temperature conditions, this coating has problems such as coating discoloration and shedding, thick coating, etc.
, which is subject to certain restrictions
in the corresponding coating technology field.
Fluorocarbon and silicone coatings have low surface energy and good anti-fouling properties, but they are more
expensive.
Therefore, the use of fluorocarbon coatings and silicone coatings low surface energy anti-pollution characteristics to modify epoxy resin powder coatings, can obtain a high temperature resistance, anti-pollution epoxy resin powder coating
.
