Siwin-M330A is an innovative silane-terminated polyether, featuring a trimethoxysilyl end-capped group and a robust PPO (polypropylene oxide) main chain. It excels in moisture-curing applications such as high-performance elastic sealants, structural sealants, and sealing coatings. Sealants formulated with M330A boast exceptional
adhesion to a broad spectrum of substrates. This advanced formulation is solvent-free, isocyanate-free, and generates no bubbles or odors during curing, making it ideal for construction, transportation, and general industrial applications.
1. Siwin-M330A reacts with water or moisture from the air; therefore, it is crucial to isolate moisture during storage and production.
2. The dosage of Siwin-M330A is highly adaptable in formulation design and can be combined with most fillers such as nano calcium carbonate, heavy calcium carbonate, fumed silica, quartz powder, diatomaceous earth, and aluminum hydroxide.
3. To prevent pre-curing, it is essential to remove water from the filler.
Siwin-V31 is typically employed as a water scavenger.
4. Commonly utilized plasticizers include phthalates (PPG, DOP, DINP, DIDP), and low molecular weight polyethers.
5. For enhanced performance, a variety of additives can be blended in, including
tackifiers, antioxidants, mildew inhibitors, and light stabilizers.

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, providing superior adhesion to numerous substrates without the need for pretreatment.
Its low glass transition temperature ensures stable mechanical properties across a wide temperature range.
High activity, medium-high modulus
Highly transparent
Excellent adhesion strength and tensile elasticity
Fast curing, can be formulated to be tin-free
Outstanding resistance to aging and yellowing
Exceptional elastic recovery rate
Solvent-free, odorless, and eco-friendly
Package: Available in 20KG, 200KG iron drums, or 1000KG ton barrels.
Storage: Generally packed in clean, dry, sealed, leak-free iron drums. Store away from sunlight, rain, fire, and open air. Avoid open flames and prolonged heating. Prevent from entering groundwater or surface water as it is non-biodegradable. In case of overflow, cover with sawdust, yellow sand, cloth, or other absorbent materials, then shovel into waste.
