Polysiloxane Modified Polyisocyanates for Use in Coatings |
摘要 |
The invention relates to an isocyanate-terminated polysiloxane material that can preferably be used as a curing agent, hardener or co-reactant in coatings. The invention further relates to a method of manufacturing the isocyanate-terminated polysiloxane material by partially hydrolyzing a methoxy-functional polysiloxane such as a methyl phenyl polysiloxane, and reacting it with a polyisocyanate to yield the isocyanate-terminated polysiloxane hardener. The hardener can preferably be used with any isocyanate-reactive functional group of another component to form coating systems, including acrylics, polyesters, epoxies and urethanes. |

1. An isocyanate-terminated polysiloxane material comprising the following structure wherein n≧1, R1, R2, and R3 individually corresponds to a methyl, phenyl or alkyl group; wherein R4 is selected from the group consisting of cycloaliphatic groups, aromatic groups, and adducts based on hexamethylene diisocyanate (HDI), isophorone diisocyanate (IPDI), diphenylmethane diisocyanate (MDI) and toluene diisocyanate (TDI). |
