Siwin-M330A is an advanced silane-terminated polyether, uniquely endcapped by trimethoxysilyl groups with a robust PPO (polypropylene oxide) main chain. It is meticulously engineered for moisture-curing elastic sealants, elastic structural sealants, and sealing coatings. Sealants formulated with M330A exhibit unparalleled excellence in
adhesion across a diverse range of substrates. This innovative formulation is free from solvents and isocyanates, with no bubbles or odors emitted during curing. It is the optimal choice for applications in the construction, transportation, and general industrial sectors.
1. Siwin-M330A reacts with water or by absorbing moisture from the air, thus it is crucial to maintain its isolation from moisture during storage and production.
2. The dosage of Siwin-M330A offers flexible modification in formulation design, easily blending with various fillers such as nano calcium carbonate, heavy calcium carbonate, fumed silica, quartz powder, diatomaceous earth, aluminum hydroxide, etc.
3. To prevent premature curing of the product, it is essential to ensure the filler is devoid of water.
Siwin-V31 is commonly utilized as an efficient water scavenger.
4. Popular plasticizers include phthalates (PPG, DOP, DINP, DIDP, etc.), and low molecular weight polyethers.
5. For enhanced performance, other additives can be combined, such as
tackifiers, antioxidants, mildew inhibitors, and light stabilizers.

Siwin-M330A serves as a reactive binder for sealants and adhesives, potting compounds, and coatings. Curing occurs at ambient temperature in the presence of moisture and a catalyst.
Depending on the formulation, it can be prepared as either one-part or two-part systems, demonstrating exceptional adhesion to a vast array of substrates, even without pretreatment.
The product's low glass transition temperature ensures stable mechanical properties across a broad temperature spectrum.

Packaging: Available in 20KG iron drums, 200KG iron drums, and 1000KG ton barrels.
Storage: Typically packed in clean, dry, sealed, leak-free iron drums. Store away from sun, rain, fire, and air. Avoid open flames and extended heating in the air. Prevent contamination of groundwater or surface water as it is not easily biodegradable. For spills, cover with absorbent materials like sawdust, yellow sand, or cloth, then shovel the waste for disposal.
