CRESTABOND M1-90HV Methacrylate Structural Adhesive Product Overview Crestabond M1-90HV is a toughened, two component acrylic adhesive designed for bonding composites, thermoplastics and metals. This new generation of structural methacrylate adhesive meets the bonding requirements of most assembly operations, demonstrating excellent impact, peel, shear, compressive strength and fatigue resistance properties across all bonded parts. Crestabond M1-90HV is a primer-less adhesive, requiring only minimal surface cleaning of the substrates to be bonded and demonstrates high toughness in all assembled parts with a gap filling capability up to 50m. Primer-less metal application Excellent retention of toughness High strength and modulus Non-sag • Fast setting and curing • Excellent adhesion to dissimilar substrates Speeds assembly process Excellent fatigue and impact resistance Replaces mechanical fasteners Application on vertical surfaces • Reduce labour • Excellent environmental resistance • Ready-to-use two component adhesive Characteristics of Crestabond M1-90HV Characteristics Working Time/Geltime Fixture Time Flash Point Working time measured with 40g mass of adhesive with 10:1 mix ratio by volume at 24°C.

Surface preparation, such as mechanical abrasion, is likely to be needed on gel coat surfaces and moulded surface where release agents are likely to be present. When bonding epoxy laminates please test bond strength prior to application. Application Crestabond M1-90HV is supplied ready to use in pre-packed 400ml and 825ml cartridges and in bulk (18Kg pails and 180Kg drums). Prior to bonding, ensure the substrate surface is clean by following instructions provided. Bulk dispensing equipment should be in good operating condition. Dispense the adhesive at slow rate initially onto a nonbonding surface...
