Borchi® Coll 20

Technical Datasheet | Supplied by Borchers (Milliken)

Borchi® Coll 20 by Borchers (Milliken) is an anti-blocking additive for all water-based paints and coatings. Shows a low matting effect and enhances surface hardness at low film builds.

It improves adhesion to wood, plastic & metal surfaces.
It reduces the tendency towards under-rusting as a result of improved film quality and a more uniform distribution of barrier properties on the substrate.
It offers better thermal endurance & corrosion resistance and avoids the blooming effect in wood coatings.
It also exhibits increased hiding power, whiteness-blocking and water- & alcohol resistance.
Borchi® Coll 20 is suitable for silk finish and gloss emulsion coatings.
The recommended dosage level is 1-3% active substance relative to total paint formulation.
