Crestabond® M1-30 - 1

CRESTABOND M1-30 Methacrylate Structural Adhesive Introduction Crestabond M1-30 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 M1-30 is a primerless 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 50mm. Features • • • • • • • • Primerless metal application Excellent retention of toughness High strength and modulus Non-sag Fast setting and curing Excellent adhesion to dissimilar substrates Excellent environmental resistance Ready-to-use two component adhesive Speeds assembly process Excellent fatigue and impact resistance Replaces mechanical fasteners Application on vertical surfaces Reduce labour Characteristics of Crestabond M1-30 Characteristics Typical Value Working Time/Geltime Fixture Time Flash Point Mixed Colour Available in Grey or Black Working time measured with 40g mass of adhesive with 10:1 mix ratio by volume at 24°C.

Do not use gasoline (petrol), low grade alcohol or paint thinners. i) Metals The surface should be clean and dry by using an alcohol/solvent wipe and allowing the solvent to evaporate before application. ii) Thermoplastics The surface must be clean, dust-free and dry. A suitable solvent such as iso-propanol can be used to degrease. iii) Composites The surface must be clean, free of dust and dry. This can be achieved by the use of proprietary strippable cloths such as peel-ply (without lubricant contaminates). The laminate should be fully cured prior to bonding and if the laminate surfaces...
