Description

SCIGRIP® SG300 Series Methacrylate Adhesives are two-component, 10:1 mix ratio products for bonding metals, composites and other plastic parts. Most metals can be bonded without primer. These advanced products are designed to meet specific requirements of the transportation industry, including reduced read through on show surfaces.

Features & Benefits

Choice of 5, 15 and 40 minute working times
Reduced bond line read through means less post finishing requirements
Excellent environmental resistance in harsh operating environments
Bonds a range of substrates: Acrylic, PVC, ABS, Thermoset Composites (Vinylester, Polyester, Gelcoats, and Epoxy), Primed Metals
Excellent fatigue, impact and shock load resistance
Primerless metal bonding requires no surface treatment or primers for most metals
