What is an SMP adhesive?
Silyl modified polymers (SMPs) are moisture curing, 1K and 2K elastic solutions that can function as both sealants and adhesives. Combining the advantages of silicone and polyurethane chemistries, SMPs are free of isocyanate, solvents and PVC and are extremely flexible.
What is MS polymer adhesive?
MS Polymer Adhesive & Sealant is a highly elastic, high strength sealant and adhesive. Modified silicone polymers (MS Polymers) offer the best all round sealant and adhesive on the market, it excels where elastic construction joints are required. It is odourless, neutral and free of isocyanates.
What is silane adhesive?
Silanes are used widely in sealants and adhesives to improve the adhesiveness of te product. Silanes can form durable bonds in metal, glass, ceramic and other surfaces. Hence these type of sealants are used in a range of industries including aerospace, automotive and construction.
What is silane polyether?
Silane terminated polyether polymers offer a low viscosity in the range of 8,000-12,000 cps despite their high molecular weight. The silane groups provide a non-isocyanate curing mechanism, good adhesion to various substrates, and good storage stability.
Is polymer the same as silicone?
In addition to this, silicone is an inorganic compound not as strong or durable as polymer based products. Tests show that it can remain flexible up to 350% at the break point, compared to about 280% with silicone.
What is silane terminated polymer?
Silyl-modified polymers (SMP; also silane-modified polymers, modified-silane polymers, MS polymers, silane-terminated polymers, etc.) are polymers terminating with a silyl group. SMPs are the main components in solvent-free and isocyanate-free sealant and adhesive products.
How do you use silane primer?
Place SILANE PRIMER on the etched surface with the use of microbrush and leave it for 60 seconds. Dry the surface with a spray of air. Place Cement for fixation in accordance with instruction for use. Don’t allow contamination of the surface.
What is silyl terminated polymer?
Silyl terminated polymers provide environmental resistance, superior adhesion properties, and fast cures, combining many of the benefits of polyurethane and silicone sealants into one material. They are generally flexible, durable, tear resistant, and hold up well in low-temperature environments.
What is the difference between polymer and silicone?
In addition to this, silicone is an inorganic compound not as strong or durable as polymer based products. These, in contrast offer long lasting protection. Polymer has a much greater cohesion strength. Tests show that it can remain flexible up to 350% at the break point, compared to about 280% with silicone.
Why are SMP adhesive and Sealant Systems widely used?
It is no wonder SMP adhesive and sealant systems are widely used, since they come with a great spectrum of advantages. Elastic bonds and seams: SMP adhesive and sealant systems remain flexible also after complete cure. The elasticity of the seams and bonds is not affected even by harsh environments.
When was Silyl modified polymer adhesive and sealant introduced?
First introduced in Japan at the end of the 80´s, silyl modified polymer adhesive and sealant solutions are becoming more and more desired in industrial applications that require elastic bonding or sealing.
What are the two types of silyl modified polymers?
The silane groups can be independent or supported by urethane groups. This gives us two main types of SMP adhesive and sealant systems: silyl modified polyethers (MS polymers) and silyl modified polyurethanes (SPUR polymers). The former are often preferred as sealants as they are more elastic and slightly less resistant than SPUR polymers.
What does SMP stand for in Science category?
SMP, nucleophilic attack of silicon and depolymerization phenomena in sealants and adhesives. These phenomena have caused controversy, civil and criminal cases like windscreens that are detached while the car is traveling.
