L708 Coupling Agent for Powder Coating

L708  Coupling Agent

Most of inorganic filler belongs to hydrophilic in powder coatings, but resin belongs to hydrophobic. Because of above reason, these two groups get difficult to dispersing. Now coupling agent can make these two groups react so that crosslink resin and pigment and increasing impact resistance, adhesion and flexural property

1.Technical parameters 

Appearance: white powder 
Volatile content: ≤ 0.5% 


Used for all kinds of thermosetting powder coatings. 

3.Use method 

Dosage: 1-2%. Mixed with pigment rapidly first, then add resin to blend.

4.Product characteristics 

1.Coupling agent contains oelophilic group and hydrophilic group, so that can crosslink resin and pigment
