PRIMERS: OVERVIEW

TECHGRIPTM PRIMERS Surface primers offering reliable high adhesion with spray and cast polyurea / polyurethane elastomers. M3: For adhering cast polyurethane and solvented spray polyureas to metal substrates. Single-component, low-viscosity, long application window. Typically provides 60-90 pli adhesion to blasted steel. E1: For bonding spray and cast polyurea / polyurethane elastomers to cured polyurethane / polyurea elastomers and certain rubber elastomers. E1-P: E1 version for bonding all Techthane and other spray and cast polyureas / polyurethanes to cured polyurethane / polyurea and certain rubber elastomers, plus high adhesion to plasticized PVC and ABS. FG1: For adhering polyureas / polyurethanes to fiberglass, epoxies, and many composite substrates with all spray coatings and cast resins; for steel substrates with 100% solids spray polyureas / polyurethanes. Medium viscosity, short tack-free time, fast overcoating application window. Typically provides 70-120 pli adhesion to prepared fiberglass and steel. C2: For dry or wet concrete and metal substrates with all spray linings and cast resins, for aluminum with 100% solids spray linings. Medium viscosity, long-pot life, medium tack-free time, long overcoating application window. Non-flammable, low VOC. Typically provides 60-110 pli adhesion to solid, prepared concrete and metals. C2-G: C2 version optimized for adhesion of polyurea / polyurethane elastomer to galvanized surfaces. C1: 100% solids epoxy primer/resurfacer for concrete, metals, and other rigid substrates. Non-flammable, 0 VOC. R1: Primer / pre-primer for bonding spray and cast polyureas / polyurethanes to Neoprene, SBR, natural, and other rubber substrates.
