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
Appearance: white powder
Used for all kinds of thermosetting powder coatings.
Dosage: 1-2%. Mixed with pigment rapidly first, then add resin to blend.
1.Coupling agent contains oelophilic group and hydrophilic group, so that can crosslink resin and pigment
Store in cool and dry place. Keep away from fire and heat sources.
