Alcohol hydroxy double-terminated long chain alkyl silicone oil MY8807
MY8807 is a double hydroxyl groups silicone oligomer. Similar activity with polyester glycol and polyether glycol. It can copolymerize with –NCO, mainly for synthesize modified silicone PU resin and emulsion. Greatly enhance resin anti-abrasion. It gives excellent touch feel, anti-sticking, anti-fouling and anti-graffiti.

Method of Application:
For synthesis of PU resin and emulsion： 1, Add silicone intermediate with polyhydric alcohols monomer at the same time. 2, Copolymerize with MDI, TDI normally about in 85℃. 3, Copolymerize with IPDI, suggest about 110℃
For Di-component PU or amino baking paint: disperse and add to resin
