MS Polymer/

Dimethoxy(methyl)silylmethylcarbamate-terminated polyether



Description

Siwin-M310  is a silane terminated polyether, which is endcapped by methyldimethoxysilyl group, the main chain is PPO (polypropylene oxide). It hydrolyzes in the presence of moisture with catalyst (such as: amine catalysis, or Tin and other heavy metal) by releasing methanol and finally form a stable siloxane network. It is a clear liquid polymer with the high reactivity, which is made into the sealant and adhesive.

Then products have excellent adhesion, weather resistance, better environmental protection etc.

Applications

Used as a reactive binder for sealants and adhesives, potting compounds and

coatings. Curing takes places at ambient temperature in the presence of both moisture and catalyst.


Depending on the formulation, either prepared as onepart or two-part systems, shows good adhesion to a

wide variety of substrates even without pretreatment.

The low glass transition temperature allows stable mechanical properties over a wide temperature range.


Processing

Siwin-M310 can react with water or by absorbing moisture from the air, so it is important to isolate moisture during storage and production.

The dosage of Siwin-M310 can be flexibly changed in the formulation design, and it can be mixed with most fillers such as nano calcium carbonate, heavy calcium carbonate, fumed silica, quartz powder, diatomaceous earth, aluminum hydroxide, etc..

In order to avoid pre-curing of the product, it is necessary to remove water from the filler. Siwin-V31 is generally used as a water scavenger.

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

In order to get better performance, you can mix other additives together, for example, tackifiers, antioxidants, mildew inhibitors, light stabilizers, etc.


Packaging

In 200L PVF steel drum.

                                                                          

Safety and Storage

Keep in a cool and dry place and avoid storage in direct sunlight. It is non-hazardous substance.
