PRIMERS: OVERVIEW

TECHGRIPTM PRIMERS User-friendly primers / surface treatments offering reliable high adhesion. M3: For metal substrates with solvented spray coatings and cast resins. Single-component, low-viscosity, long application window. Typically provides 60-90 pli adhesion to blasted steel. FG1: For fiberglass, epoxies, and many composite substrates with all spray coatings and cast resins; for steel substrates with 100% solids spray coatings. Medium viscosity, short tack-free time, medium Techthane application window. Non-flammable, VOC exempt. Typically provides 70-120 pli adhesion to prepared fiberglass and steel. C2: For dry or wet concrete and metal substrates with all spray coatings and cast resins, for aluminum with 100% solids spray coatings. Medium viscosity, long-pot life, medium tack-free time, long Techthane application window. Non-flammable, low VOC. Typically provides 60-110 pli adhesion to solid, prepared concrete and metals. C2-G: Special C2 version optimized for adhesion to galvanized surfaces. C1: 100% solids epoxy primer/resurfacer for concrete, metals, and other rigid substrates. Non-flammable, 0 VOC. E1: For bonding all Techthane elastomers to cured urethane and certain rubber elastomers. Typically provides >100 pli adhesion to properly prepared cured Techthane elastomers. E1-P: Special E1 version for bonding all Techthane elastomers to cured urethane and certain rubber elastomers, plus adhesion to plasticized PVC substrates. H1: Primer / pre-primer for Hypalon® substrates.
