Application

(1) Coatings: Recommended for enhancing adhesion of UV/ EB cured coatings, ie acrylic, etc. to metal surfaces with resultant reduction in corrosion. Enhances adhesion to many plastic surfaces (oxygen containing polymers only) or treated polyolefins.

(2) Adhesives/ Sealants: Recommended for acrylate/ methacrylate adhesives and sealants for improved adhesion to metals, concrete, wood, many plastics (oxygen containing polymers only) and ceramics. Improved T-peel strength and resistance to moisture. Not recommended for adhesion to glass.

(3) Rubber: Improved physical properties in mineral filled silicone, EPDM and other peroxide cured rubbers.

(4) Plastics: Improved physical properties in free radical cured resins, ie polyesters, acrylics, and polyurethanes.

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.

(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, i.e. fumed silica, carbon black, phthalo, and similar use 3.0-5.0 phf.

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