Siwin-M330A is a premium silane terminated polyether, expertly endcapped by trimethoxysilyl groups, with a robust polypropylene oxide (PPO) main chain. This versatile polymer is ideal for moisture-curing elastic sealants, elastic structural sealants, and sealing coatings. Sealants crafted from M330A exhibit unparalleled adhesion properties and cater to a wide range of substrates. Notably, this formulation is solvent-free and devoid of isocyanates, ensuring no bubbles or unpleasant odors during curing, making it particularly well-suited for the construction, transportation, and general industries.
This formulation offers exceptional adhesive qualities across a broad spectrum of substrates. It's free from solvents and isocyanates and generates no bubbles or odors during curing. Perfect for construction, transportation, and general industry applications.
1. Siwin-M330A reacts with water or ambient moisture, necessitating the isolation of moisture during storage and production.
2. The dosage of Siwin-M330A is adaptable in formulation design, compatible with most fillers like 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 water from the filler.
Siwin-V31 is typically employed as a water scavenger.
4. Common plasticizers include phthalates (PPG, DOP, DINP, DIDP), and low molecular weight polyethers.
5. For enhanced performance, blend with other additives like tackifiers, antioxidants, mildew inhibitors, and light stabilizers.

Ideal as a reactive binder for sealants, adhesives, potting compounds, and coatings. 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, demonstrating 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-medium Modulus
Highly transparent
Outstanding adhesion strength and tensile elasticity
Rapid curing, can be tin-free
Excellent resistance to aging and yellowing
Superior elastic recovery rate
Solvent-free, odorless, eco-friendly
Package: 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 prolonged heating. Prevent it from entering groundwater or surface water as it is not easily biodegradable. In case of overflow, cover with absorbent materials like sawdust, sand, or cloth, and then shovel to waste.
