Overview

SCIGRIP SG3000 is a high-strength, toughened two-component methacrylate adhesive specifically engineered for the structural bonding of electroplated and hot dip galvanized steels and other zinc-coated metals, without the need for surface primers or extensive pretreatment.

With a straightforward 1:1 mix ratio, SG3000 offers rapid strength build-up, excellent environmental resistance, and a non-sag formula that keeps the adhesive in place on vertical and angled surfaces. Its ability to bond metals with composites and a range of plastics makes it the premier choice for mixed-material assemblies in transportation, construction, and architectural applications.

From bonding galvanized structural fittings and composite cladding panels to marine handrails and wind energy mounting hardware, SG3000 delivers the high-strength, primerless performance needed where galvanized steel is the substrate.
