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) 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

∎Directions for Use

● Cleaning:The substrate surface must be solid, dry and be clean.Such as no dust, grease, asphalt, tar, paint, wax, rust, water repellent, curing agent, isolating agent and film. Surface cleaning can be dealt with by removing, cutting, grinding, cleaning, blowing, and so on.

● Operation:Put the sealant into the operating tool,then injecting it into the gap.

● Reservation gap:The construction joint will expand as the temperature change,so the surface of the sealant should be lower than 2mm of the pavement after construction.

● About maintenance time: At the standard state, the maintenance time is about 5 hours. It depends on the actual construction conditions. The standard state is that the temperature is 23±2℃,and the humidity is 55 ± 5%RH.

● Operation Methods: Because the packing is different, the construction methods and tools are slightly different. The specific construction method.
●Used in automobiles, buses, elevators, ships, containers, tunnels, rail transit, waterproof dams, nuclear power plants, airport runways, houses, elevated, anti-smashing walls, etc., suitable for high-strength structural bonding and sealing. Suitable substrates include aluminum-plastic panels, marble, wood, concrete, PVC injection molded parts, glass, fiberglass, steel, stainless steel, and aluminum alloys (including painted).
