MS 55 High Modulus Multi purpose MS sealant
MS 55 High Modulus Multi purpose MS sealant
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) joints
Industrial 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

Instructions
Spur Adhesive/Sealant MS 55 may be over-painted, however due to the large number of paints and varnishes available we strongly suggest a compatibility test before application. The drying time of alkyd resin based paint may increase.
Application
The surfaces to be treated should be perfectly clean, dry and free from dust and grease.
Primers may be required on some substrates and in certain application cycles. It is
recommended that our Technical department should be consulted with regards the choice of Primer for specific purposes.
