Siwin-M330A is a revolutionary silane-terminated polyether featuring a trimethoxysilyl end group and a robust PPO (polypropylene oxide) main chain. This advanced material is ideal for moisture-curing elastic sealants, elastic structural sealants, and sealing coatings. Sealants formulated with M330A not only deliver exceptional performance but also meet a broad spectrum of substrate requirements.
The formula boasts outstanding adhesion properties, accommodating a wide range of substrates. Free from solvents and isocyanates, it ensures no bubbles or odors during curing. Perfectly suited for the construction, transportation, and general industries, M330A stands out as a superior choice.
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 dosage of Siwin-M330A is highly adaptable in formulation design and can mix easily with most fillers, including nano calcium carbonate, heavy calcium carbonate, fumed silica, quartz powder, diatomaceous earth, aluminum hydroxide, and more.
3. To prevent pre-curing, it is essential to remove water from the filler. Siwin-V31 is typically used as an effective water scavenger.
Siwin-V31 is generally used as a water scavenger.
4. Common plasticizers include phthalates (PPG, DOP, DINP, DIDP) and low molecular weight polyethers.
5. For enhanced performance, mix in other additives like tackifiers, antioxidants, mildew inhibitors, light stabilizers, and more.

Fast Curing, Tin-Free Capabilities
Excellent Aging and Yellowing Resistance
Superior Elastic Recovery Rate
Solvent-Free, Odorless, and Eco-Friendly
Package: 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 sunlight, rain, fire, and air. Avoid open flames and prolonged heating in the air. Since it is not easily biodegradable, prevent it from entering groundwater or surface water. In case of spillage, cover with absorbent materials like sawdust, yellow sand, or cloth, then shovel into waste.
