MY 2841 single-ended single-hydroxyl silicone oil
Product Description
It is a single-ended single-hydroxyl functional organosilicon oligomer with a low molecular weight. It can react with -NCO, -NH2, COOH and epoxy groups, and is mainly used in organosilicon-modified PU, PUD, TPU, modified polyester resin, acrylic resin, 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% of TPU polymer systems can achieve demolding and anti-sticking effects. If the addition amount is increased to 3-10%, it can provide excellent hydrophobicity, stain resistance, and silicone-like touch. It can react synchronously with polyols. For esterification reactions, it can replace part of the polyols, and it is recommended to use a stepwise reaction approach. |
