Siwin-M330A is a state-of-the-art silane-terminated polyether, capped with trimethoxysilyl groups, and boasts a polypropylene oxide (PPO) backbone. This advanced material is perfect for moisture-curing elastic sealants, structural sealants, and sealing coatings. Sealants formulated with M330A not only exhibit superb
adhesion properties to a broad range of substrates but also ensure a solvent-free, isocyanate-free, bubble-free, and odorless curing process. Ideally suited for the construction, transportation, and general industries, it sets new standards in performance and safety.
1. Siwin-M330A reacts with water or absorbs moisture from the air, thus it is crucial to keep it isolated from moisture during storage and production.
2. The dosage of Siwin-M330A can be adjusted flexibly in formulation design and can blend seamlessly with various fillers such as nano calcium carbonate, heavy calcium carbonate, fumed silica, quartz powder, diatomaceous earth, and aluminum hydroxide.
3. To prevent pre-curing of the product, ensure that fillers are dry before use.
Siwin-V31 is commonly used as a water scavenger.
4. Common plasticizers include phthalates (PPG, DOP, DINP, DIDP, etc.) and low molecular weight polyethers.
5. For enhanced performance, you can incorporate additional additives such as
tackifiers, antioxidants, mildew inhibitors, and light stabilizers.

Siwin-M330A excels as a reactive binder in sealants, adhesives, potting compounds, and coatings. It cures 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 excellent adhesion to a wide variety of substrates even without pretreatment.
Its low glass transition temperature ensures stable mechanical properties across a broad temperature range.
High activity, high to medium modulus
High transparency
Excellent adhesion strength and tensile elasticity
Fast curing, tin-free options available
Superior aging and yellowing resistance
Outstanding elastic recovery rate
Solvent-free, odorless, and eco-friendly
Package: Available in 20KG and 200KG iron drums, or 1000KG ton barrels.
Storage: Store in clean, dry, sealed, leak-free iron drums. Keep away from sunlight, rain, fire, and air. Avoid open flames and prolonged heating. Prevent contamination of groundwater or surface water; in case of overflow, cover with absorbent materials like sawdust, sand, or cloth and then shovel into waste.
