Preparation of high temperature resistant powder coating

Preparation of high temperature resistant powder coating

High temperature resistant powder coating is a special functional coating.

The powder coating is generally cured into a film under the condition of 10-15min@180-200℃, which is a thermosetting coating, and its coating forms a network cross-linked structure, so the heat resistance of thermoplastic coatings is improved to a certain extent

—The order of side groups to thermal stability: phenyl>methyl>ethyl>propyl>butyl>hexyl;

—The content of silica affects the temperature resistance of the coating;

-Silanol content affects the cross-chain density of silicone resin;

—TG affects the storage and sprayability of coatings online coatingol.

Choose the type and amount of silicone resin to be added according to the temperature resistance requirements and use time.

Reference formula for high temperature resistant powder coating

The new high temperature resistant powder coating is mainly composed of high temperature resistant resin, high temperature resistant pigments, fillers and special functional additives.
