Application Information

SMC, BMC, Pultrusion
Special Features and Benefits

Solvent-free wetting and dispersing additive (100% active substance) to wet inorganic fillers (and inorganic pigments) in systems in which solvents need to be avoided.

Recommended Levels
0.5-1% additive (as supplied) based upon fillers for wetting and dispersion.
0.25-1% additive (as supplied) based upon resin for stabilizing the viscosity in BMC.
The above recommended levels can be used for orientation. Optimal levels are determined through a series of laboratory tests.
Incorporation and Processing Instructions
BYK-W 9010 should be added to the resin mixture prior to homogenization and the addition of the fillers/pigments.

 

Adhesives & Sealants
Special Features and Benefits

Solvent-free wetting and dispersing additive (100% active substance) to wet inorganic fillers (and inorganic pigments) in systems in which solvents need to be avoided.
Recommended Use
The additive is particularly recommended for adhesives based on epoxy resins and UV systems.
Recommended Levels
0.5-1% additive (as supplied) based on the filler.
The above recommended levels can be used for orientation. Optimal levels are determined through a series of laboratory tests.
Incorporation and Processing Instructions
For optimum performance, the additive should be added before the solids.
