Application

(1) Adhesives: Recommended for epoxy, urethane, and rubber adhesives to enhance adhesion to metals, plastics and elastomers. Increased T-peel strength. Improved resistance to moisture, heat and corrosive environments.

(2) Coatings: Recommended for enhancing adhesion of epoxy, urethane, alkyd, acrylic, polyester and other solvent-borne coatings to metal surfaces with resultant reduction in corrosion. Also enhances adhesion to many plastic surfaces. Useful in most water-borne coatings (Latex and polymer dispersion) for enhanced adhesion to metal and plastic substrates.

Technical Details & Test Data

Procedure
  • HIGH SHEAR MIXING NECESSARY IN ALL SOLVENT-BORNE SYSTEMS

1. Coatings/ Inks: Optimum performance is achieved when added directly to the grind stage resin and high shear mixed for 15 mins before adding other components. Must be high shear mixed with a Cowles type mixer. Milling alone is not sufficient.

  • Two component epoxies: Add to resin (A side); level is 1.0 - 2.0 wt. per cent of total binder (combined resin + hardener)
  • Two component urethanes: Add to polyol (B side); level is 1.0 - 2.0 wt. per cent of total binder (combined isocyanate +polyol).

2. Adhesives: 1.0-2.0 phr, post add recommended under agitation

3. Plastics: 1.0-2.0 phf (parts per hundred filler; recommend pretreat of pigments/ fillers in a Henschel or similar mixer and subsequently compound with resin. For high surface area pigments/ fillers, ie fumed silica, carbon black, phthalo, and similar.

4. Rubber: 1.0-3.0 phr, add directly onto silica or other filler and compound in a Banbury mixer.
