High Modulus Multi-purpose MS Sealant MS 55
Product Description
MS 55 Adhesive/Sealant is a one-part, High modulus, Silyl-Terminated Polymer Adhesive-Sealant. Once extruded it cures by reaction to the atmospheric moisture to form a high performance, permanently flexible elastic adhesive.Characterised by a high thixotropy it has a good initial grab (green strength)
• Environmental friendly – Free of isocyanates and solvents
• No Hazard symbol required
• Odourless
• Permanently flexible
• No change in volume – No shrinkage
• No bubble formation
• Primer-less adhesion on almost every substrate
•Non-sag consistency - Exceptional thixotropy – load bearing capacity
•High mechanical/dynamic stress resistance – shock/impact resistant
• Increase torsional stiffness of final assembly
• Vibration and sound damping properties
• Excellent weathering resistance - extremely good colour stability and UV resistance
•Over-paintable with many water, solvent based paints (preliminary tests recommended)
Automotive Uses
• Automotive sheet metal
• Transport (bus, caravan, refrigerated truck), container
• Bonding of glass and steel roof top (van, cabin) jointsIndustrial Uses
• Bonded layers (plywood, wood and metal), floor or metal frames
• Bonding all external or internal panels, walls, plate corners or tubular frames
• Elastic and structural bonding applications required in industry (assembly of insulation panels; anti-vibration bonding and sealing of steel, aluminum, wood, glass steel and other plastic materials and components made of coated surfaces)
• Sealing: particularly large joints
