Discover the brilliance of Siwin-M330A, a silane-terminated polyether with a trimethoxysilyl endcap and a robust PPO (polypropylene oxide) main chain. This exceptional polymer is ideal for moisture-curing elastic sealants, structural sealants, and sealing coatings. Sealants formulated with M330A not only offer superior adhesion but also boast a wide compatibility with various substrates. The solvent-free and isocyanate-free formulation ensures a bubble-free and odorless curing process, making it perfect for applications in the construction, transportation, and general industries.
Siwin-M330A is renowned for its outstanding adhesion properties across a myriad of substrates. The solvent-free formulation is devoid of isocyanates, ensuring no bubbles or unpleasant odors during curing. This makes it an excellent choice for the construction, transportation, and general industries, providing reliability and versatility in every use.
1. Siwin-M330A reacts with water or moisture from the air. Therefore, it's crucial to keep it isolated from moisture during storage and production to prevent premature curing.
2. The dosage of Siwin-M330A can be adjusted flexibly in formulation design, seamlessly blending with fillers like nano calcium carbonate, heavy calcium carbonate, fumed silica, quartz powder, diatomaceous earth, and aluminum hydroxide.
3. To prevent pre-curing, ensure the removal of water from fillers. Siwin-V31 is commonly used as an effective water scavenger in these formulations.
Siwin-V31 is the go-to choice for water scavenging in formulations, ensuring optimal performance of Siwin-M330A.
4. Common plasticizers compatible with Siwin-M330A include phthalates (PPG, DOP, DINP, DIDP), low molecular weight polyethers, and more, providing flexibility in formulation design.
5. Enhance performance by incorporating other additives like tackifiers, antioxidants, mildew inhibitors, light stabilizers, and more to achieve the desired properties.
Incorporate a variety of additives such as tackifiers, antioxidants, mildew inhibitors, and light stabilizers to enhance the performance of your formulation.
