Siwin-M330A is a top-tier silane-terminated polyether, endcapped with a trimethoxysilyl group. Its main chain is composed of high-quality PPO (polypropylene oxide). This marvel is perfect for formulating moisture-curing elastic sealants, structural sealants, and sealing coatings. Sealants crafted from M330A boast superior
adhesion properties and can bond with a broad array of substrates. Remarkably, this formulation is free from solvents and isocyanates, ensuring no bubbles or odors during curing. It is an ideal choice for applications in the construction, transportation, and general industrial sectors.
1. Siwin-M330A reacts with water or moisture in the air, making it crucial to isolate it from moisture during storage and production.
2. The flexible dosage of Siwin-M330A allows for versatile formulation designs. It can be blended seamlessly with most fillers, including nano calcium carbonate, heavy calcium carbonate, fumed silica, quartz powder, diatomaceous earth, aluminum hydroxide, etc.
3. To prevent pre-curing, it is essential to remove moisture from the filler.
Siwin-V31 is commonly employed as an efficient water scavenger.
4. Widely-used plasticizers include phthalates (PPG, DOP, DINP, DIDP, etc.), low molecular weight polyethers, among others.
5. For enhanced performance, consider mixing additional additives like
tackifiers, antioxidants, mildew inhibitors, and light stabilizers.

Ideal as a reactive binder for sealants, adhesives, potting compounds, and coatings. Curing transpires at ambient temperature, facilitated by moisture and catalysts.
Depending on its formulation, it can be prepared as either one-part or two-part systems, demonstrating excellent adhesion to diverse substrates, even without pretreatment.
Its low glass transition temperature ensures stable mechanical properties across a wide temperature range.

Packaging: Available in 20KG iron drums, 200KG iron drums, and 1000KG ton barrels.
Storage: Typically packed in clean, dry, sealed, and leak-free iron drums. Keep away from sunlight, rain, fire, and air. Avoid open flames and extended heating in the air. Do not allow it to enter groundwater or surface water as it is not easily biodegradable. In case of overflow, use absorbent materials like sawdust, yellow sand, or cloth to cover and then shovel into waste.
