MY 2822F4 single-ended dihydroxy silicone oil
Product Description
It is a well-compatible single-ended dihydroxy functional organosilicon prepolymer that can react with -NCO, -NH2, COOH, etc., and is mainly used for organosilicon modification
PU, PUD, TPU, modified polyester resin, acrylic resin, etc.
Product features
1. It can partially replace diols during resin synthesis and has high activity.
2. It can provide certain anti-sticking, anti-stain and anti-graffiti properties;
3. Good compatibility, relatively stable foam, and can be used in foaming systems;
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. |
|
Two-component PU paint and amino resin baking paint |
Carboxylic hydroxyl groups have good activity. Under high-temperature conditions, they can participate in reactions with -NCO groups and amines, and provide slipperiness and stain resistance by means of free silicone segments on the polymer surface. |
Storage and Transportation
