Introducing the Siwin-M330A, a cutting-edge silane-terminated polyether. Endcapped by trimethoxysilyl groups and featuring a PPO (polypropylene oxide) main chain, this advanced material is ideal for moisture-curing elastic sealants, structural sealants, and sealing coatings. M330A-based sealants not only boast superior adhesion properties, but they also offer versatility across a broad range of substrates. Designed without solvents or isocyanates, this formulation ensures no bubbles or odors are generated during curing, making it perfect for the construction, transportation, and general industrial sectors.
Embrace the exceptional adhesion properties of the Siwin-M330A, designed to adhere robustly to a wide array of substrates. This unique formulation is free from solvents and isocyanates, ensuring a bubble-free and odorless curing process. Ideal for construction, transportation, and general industrial applications, Siwin-M330A sets a new standard in high-performance industrial sealants.
1. Siwin-M330A reacts with water or moisture from the air, necessitating careful storage and production to prevent exposure to moisture.
2. The dosage of Siwin-M330A is highly adaptable in formulation design and can be seamlessly combined with most fillers, including nano calcium carbonate, heavy calcium carbonate, fumed silica, quartz powder, diatomaceous earth, and aluminum hydroxide.
3. To prevent premature curing, it is crucial to eliminate water from fillers. Siwin-V31 is commonly used as a water scavenger in such scenarios.
Siwin-V31 is the go-to choice for acting as a water scavenger to ensure the integrity of the formulation.
4. Commonly used plasticizers include phthalates (PPG, DOP, DINP, DIDP), and low molecular weight polyethers.
5. Enhance the performance of your formulation by blending in additional additives such as tackifiers, antioxidants, mildew inhibitors, and light stabilizers.
To achieve superior performance, consider integrating additives like tackifiers, antioxidants, mildew inhibitors, and light stabilizers.

Siwin-M330A serves as a reactive binder for sealants, adhesives, potting compounds, and coatings. It cures at ambient temperature in the presence of both moisture and a catalyst.
Depending on the formulation, Siwin-M330A can be prepared as either one-part or two-part systems. It exhibits excellent adhesion to a myriad of substrates without the need for pretreatment.
Its low glass transition temperature ensures stable mechanical properties across a broad temperature range.
