CAS NO: 156327-07-0

EINECS NO.: 605-054-4

 

Chemical Structural Formula

n=30, m=3, average molecular weight 3550, hydroxyl value 25.0 (KOHmg/g) and -NCO, -COOH have high reactivity.

 

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.

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
