Matting Curing Additive 54553-90-1 For Paint

HT-802 Matt Hardener

Coating matt hardener plays an important role in coating industry. The main functions of matt hardener that used in coating are

to promote coating's drying speed and curing speed.

Form the view of functional system, there are two different methods to explain how coating hardener promotes the coating drying

speed. One is the physical drying method and the other is chemical curing method. According to the physical method's working

principle, coating hardener should react with oxygen in air to promote the coating's drying speed. According to the chemical curing

method's working principle, coating hardener reacts with the main paint to form a cross-linked structure to promote coating drying.

In terms of classification, paint curing agents can be divided into many types, which have different performance characteristics according

to their ingredients and application areas. Our HT-802 coating hardener is very suitable to use in the coating that matte surface is needy.
