Application

(1) Coatings/ Inks: Recommended for all water-borne coatings having a pH of 7-11; including coatings formulated with acrylic/ styrenated acrylic latex emulsions, and water-borne polymer dispersions of alkyds, epoxies, urethanes and others.

• Will improve adhesion to all metals, improve salt fog resistance, reduce creep at the scribe, and reduce blistering

• Will improve adhesion to plastic films, ie treated PE/ PP and mylar

• Also, improved adhesion to many plastics, concrete, rubber, wood and ceramics

(2) Adhesives: Recommended for most acrylic and similar latex emulsion based adhesives, and waterborne epoxy/ urethane to enhance adhesion to metals, plastics, concrete, elastomers, and ceramics. Increased T-peel strength. Improved resistance to moisture, heat, and corrosive environments.

Technical Details & Test Data

Procedure

Coatings/ Adhesives: Fully compatible with coatings/ inks having a pH of 7-11. May be added directly to latex or polymer dispersion or post added in many cases. Recommended use level is 0.35 - 1.4 wt per cent based upon polymer solids + organic pigment weight + anti-corrosive pigment weight.
