MY 2812F4 double-ended monohydroxy silicone oil
Product Description
It is a two-ended single-hydroxyl functional group organosilicon prepolymer that can react with -NCO, -NH2, COOH and epoxy groups, and is mainly used for organosilicon-modified PU, PUD, TPU, modified polyester resins, etc.
Product features
1. Enhance the wear resistance and smooth hand feel of resins or coatings;
2. It can provide certain anti-sticking, anti-stain and anti-graffiti properties;
3. It can react with -NCO, -NH2, -COOH and epoxy groups;
4. Low surface tension promotes leveling and flow.

Application Fields and Usage Methods:
|
Synthesis of Organosilicon-Modified Polyurethane Resins and Dispersions |
It can be added simultaneously with polyol monomers or added in the latter stage of synthesis; it generally copolymerizes with isocyanate monomers at 85°C, and when reacting with IPDI, it is recommended to increase the reaction temperature. |
|
Used for silicone-modified TPU and polyester resin synthesis |
Generally, adding 0.2-0.5% to the TPU polymer system can achieve demolding and anti-sticking effects. If the addition amount reaches 3-10%, it can provide excellent hydrophobicity, anti-fouling and silicone hand feel, and react synchronously with polyols. It is used in esterification reactions and can replace some polyols. It is recommended or reacted in steps for better results. |
Storage and Transportation
The product has a shelf life of 12 months when stored unopened at room temperature.
Non-hazardous goods are transported as regular chemicals.
Note: Low-temperature storage may cause the product to become cloudy or solidify and other appearance differences. It needs to be heated to dissolve before use, which will not affect the product performance.
