Application
  • Coatings, Adhesives & Inks: Will improve adhesion to all metals with accompanying improved salt fog resistance, reduction of creep at the scribe, and reduced blistering; AND improved adhesion to ceramics, concrete and wood and plastics (except untreated PP/ PE). In WB Exterior primers and deck stains, will eliminate peeling on wood substrate.
  • Water-Borne Coatings: For acrylic, styrenated acrylic, PUD and alkyd coatings having pH 7-11. Use level 0.35 - 1.4 wt per cent on polymer solids*.
  • 2K Epoxy and 2K Urethane: Always add to hardener (epoxies) or polyol (urethanes). Use level 0.35 - 1.4 wt. per cent on polymer solids*.
  • Urethane modified nitrocellulose: Add with Cowles-type mixing for 10 minutes. Use level 0.35 - 1.4 wt per cent based upon binder solids.

Technical Details & Test Data

Procedure

1. Water-Borne: Post add at 0.35 - 1.4 wt% on polymer solids. Mix with conventional paddle-type mixer.

2. 2K Epoxy and 2K Urethane: Optimum performance is achieved when added to the hardener (epoxies) or polyol (urethanes). Product must be high shear mixed with a Cowles type mixer. Milling alone is not sufficient. Use Level 0.35 - 1.4 wt% on polymer solids.
