Product description:
It is a silicone oligomer with bishydroxy functional group, which has similar reactivity with polyol, copolymerization with -NCO and COOH, and is mainly used for synthesizing silicon modified polyurethane resin and emulsion, silicone modified polyester resin, etc. It can give the resin excellent hand feeling, improve wear resistance, prevent adhesion, antifouling and anti-graffiti.
Technical indicators:
Parameter value
Appearance : Colorless to slightly yellow transparent liquid
Hydroxyl content % : 0.8
Average molecular weight: 4000
Viscosity 25°C cst : 1500-2500
Solid content % : ≥98.00
Product Features:
Greatly improve the high wear resistance of the resin or coating
Excellent hand and slippery
Excellent anti-stick, anti-stain and anti-graffiti
Good resin compatibility
Highly reactive with -NCO, -COOH
Low surface tension for smoothing and flow
Applications:
Similar to polyester diol and polyether diol
Synthetic silicone modified polyurethane resin and emulsion
Two-component PU paint and amino paint
Instructions:
Polyurethane resin and emulsion synthesis: added simultaneously with the polyol monomer or added in the latter stage of the synthesis;
Copolymerization with MDI and TDI at 85 ° C
Copolymerization with IPDI is recommended at around 110 °C
Two-component PU or amino baking varnish: adding main resin and dispersing evenly
Storage and expiration date:
It is stored unopened at room temperature and has a shelf life of 24 months.
