Crystic Crestomer Structural Adhesives ® Range and Application Guide

Introduction Crystic Crestomer® structural adhesives are used in a wide range of demanding applications in a variety of markets. The key features and benefits for customers are: ● ● ● ● Improved structural performance. Productivity gains through significantly reduced construction times. Low VOC emissions. Considerable weight savings. Stronger Lighter Quicker Tougher A Record of Achievement The Crystic Crestomer pedigree was established over 25 years ago. The first commercial application for Crystic Crestomer adhesive was in the manufacture of minehunters. The unique properties of Crystic Crestomer...

Chemistry and Bonding The combination of strength, resilience and flexibility is due to the novel structure of urethane acrylate resins. The urethane component is fully reacted into the molecular backbone, thus contributing adhesive properties without the hazard associated with free di-isocyanates. The acrylate saturation and the styrene monomer impart thermoset characteristics. The backbone of Crystic Crestomers impart toughness strength and flexibility. The resulting balance of properties makes the Crystic Crestomer range ideal as a structural adhesive with the following features. ● Excellent...
