M3310 MS Polymer / Silyl-Terminated-Polyether

M3310 is alkoxy silane terminated polyether polymer. It could be applied in moisture curing elastic sealant, elastic structure sealant and sealing coatings. Sealants based on M3310 not only have excellent adhesion properties, but also have adhesion to broad range of substrates. Different from polyurethane and silicone system, this formulation have 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.

M3310 is the main resin raw material for producing adhesives, sealants, potting glue and coatings. Under room temperature, it solidifies by absorbing moisture in the air under the action of catalysts (such as amines, tin, etc.). According to needs, we can design it into a one-component or two-component system formula product, which can widely bond different substrates.

Process characteristics

1. Since alkoxy groups hydrolyze and crosslink in a humid environment, it is very important to isolate moisture during storage and production.

2. The amount of M3310 added can be flexibly changed in the formulation design, and it can be mixed with most fillers, such as nano calcium carbonate, heavy calcium carbonate, white carbon black, silica powder, diatomaceous earth, aluminum hydroxide, etc.

3. In order to avoid premature curing of the product, the filler needs to be dehydrated, and Siwin-V31 is generally used as a dehydrator.

4. Commonly used plasticizers include phthalates (PPG, DOP, DINP, DIDP, etc.), low molecular weight polyethers, etc.

5. In order to obtain better performance, it can be mixed with other additives, such as tackifiers, antioxidants, mildew inhibitors, light stabilizers, etc.
