The Scigrip SG300 series is designed to meet specific requirements of the transportation industry, including reduced read through on show surfaces. The combination of minimum surface preparation, primerless for most metal bonding and low read through makes the SG300 series products ideal for a variety of assembly operations. Features Reduced bond line read through High Viscosity - Non Slump Application High Impact Strength & Fatigue Endurance Permanent toughness Recommend Substrates Composites Metals Thermoplastics ✓ Epoxy Laminates ✓ Aluminium ✓ ABS, Acrylics ✓ FRP (Polyester / Vinyl Ester) ✓ Carbon Steel ✓ Vinyl ✓ Gelcoats ✓ Stainless Steel ✓ PVC, Polycarbonates Polyolefins, thermoplastic polyesters, fluorocarbon plastics and other low surface energy plastics are generally not bondable. Prepare metal by removing dust, loose scale, rust and other surface residue including oil and grease. For maximum bond strength on steel, abrade surface prior to bonding.
