Product Description
Siwin-M330A is a silane terminated polyether, which is endcapped by trimethoxysilyl group, the main chain is PPO (polypropylene oxide).It could be applied in moisture curing elastic sealant, elastic structure sealant and sealing coatings. Sealants based on M330A not only have excellent
adhesion properties, but also broad to a large range of substrates. 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.
1.Siwin-M330A can react with water or by absorbing moisture from the air, so it is important to isolate moisture during storage and production.
2. The dosage of Siwin-M330A can be flexibly changed in the formulation design, and it can be mixed with most fillers such as nano calcium carbonate, heavy calcium carbonate, fumed silica, quartz powder, diatomaceous earth, aluminum hydroxide, etc..
3. In order to avoid pre-curing of the product, it is necessary to remove water from the filler.
Siwin-V31 is generally used as a water scavenger.
4. Commonly used plasticizers are phthalates (PPG, DOP, DINP, DIDP, etc.), low molecular weight polyethers, etc.
5. In order to get better performance, you can mix other additives together, for example,
tackifiers, antioxidants, mildew inhibitors, light stabilizers, etc.

Product Application
Used as a reactive binder for sealants and adhesives, potting compounds and coatings. Curing takes places at ambient temperature in the presence of both moisture and catalyst.
Depending on the formulation, either prepared as one part or two-part systems, shows good adhesion to a wide variety of substrates even without pretreatment.
The low glass transition temperature allows stable mechanical properties over a wide temperature range.
High Activity , High-medium Modulus
