CAS No. 216597-12-5
CAS No.611222-18-5
Description:
MS Polymer is alkoxy silane terminated polyether polymer. It could be applied in moisture curing elastic sealant, elastic structure sealant and sealing coatings. Sealants based on it not only have excellent adhesion properties, but also have adhesion to broad range of substrates. Different from polyurethane and silicone system, this formulation has no solvent and isocyanate, as well as no bubbles and odour generated from curing. It is especially suitable for construction industry, transportation industry and general industry application.

Application:
It is used as base polymer in elastic sealants, elastic structure sealants, encapsulate adhesives and coatings. The curing mode of the polymer is moisture curing, it can be made into a single component or two- components system.
Storage:
Because this product is moisture sensitive, If unopened and stored at 4 ℃ -30℃ dry environment, the shelf life is 12 months. Use it as soon as possible if opened, the remain products should be resealed and stored at 4 ℃-30℃ dry environment. But if shelf life expired, you can still use it only after your positive confirmation of production performance.
