M330B MS Polymer / Silyl-Terminated-Polyether

M330B is a polymer of alkoxysilane-terminated polyether, and its main chain is a polyoxypropylene structure. Due to the hydrolysis and cross-linking of alkoxy groups in a humid environment, it can be used to make moisture-curing elastic sealants, elastic structural adhesives, and sealing coatings. M330B not only has excellent environmental performance, but also has excellent adhesion to different substrates. Compared with traditional sealants and adhesives such as silicone and polyurethane, it has many excellent characteristics such as no solvent, low VOC, no free isocyanate, surface paintable, and no bubbles during the curing process. It is particularly suitable for various fields such as construction, industry, transportation, and new energy.

Application

M330B is the main resin raw material for producing adhesives, sealants, potting glue and coatings. Under room temperature, it solidifies by absorbing moisture in the air under the action of catalysts (such as amines, tin, etc.). According to needs, we can design it into a one-component or two-component system formula product, which can widely bond different substrates. High-viscosity resin can reduce the amount of gas silicon added during the glue making process, reduce costs and improve the performance of the glue. With the same base material, the resin content can be increased to improve the performance of the glue.

1. Since alkoxy groups hydrolyze and crosslink in a humid environment, it is very important to isolate moisture during storage and production.

2. The amount of M330B added can be flexibly changed in the formulation design, and it can be mixed with most fillers, such as nano calcium carbonate, heavy calcium carbonate, white carbon black, silica powder, diatomaceous earth, aluminum hydroxide, etc.

3. In order to avoid premature curing of the product, the filler needs to be dehydrated, and Siwin-V31 is generally used as a dehydrator.

4. Commonly used plasticizers include phthalates (PPG, DOP, DINP, DIDP, etc.), low molecular weight polyethers, etc.

5. In order to obtain better performance, it can be mixed with other additives, such as tackifiers, antioxidants, mildew inhibitors, light stabilizers, etc.

Store in a cool, dry place and avoid direct sunlight. Product shelf life is 12 months.

Transport as a general non-hazardous chemical.
