SOLVENT-FREE, SELF-POLISHING POLYURETHANE MATRIX FOR USE IN SOLVENT-FREE ANTIFOULINGS |
摘要 |
A polyol having the formula Si(O—R1—OH)m(O—R2)nR3. Each R1 is a divalent radical derived from diethylene glycol, triethylene glycol, dipropylene glycol, or tripropylene glycol, each R2 is an aliphatic group, and R3 is an alkyl group or aromatic group. The value m is 2 or 3 and n is 0 or 1. A process of making the above polyol by: providing a reactant having the formula Si(O—R2)3R3, and reacting the reactant with a diol having the formula HO—R1—OH. An antifouling coating comprising a thermoset formed by reacting a polyisocyanate with the above polyol. The coating is not a foam. |

1. A polyol having the formula Si(O—R1—OH)m(O—R2nR3;
wherein each R1 is an independently selected divalent radical derived from diethylene glycol, triethylene glycol, dipropylene glycol, or tripropylene glycol; wherein m is 2 or 3; wherein each R2 is an independently selected aliphatic group; wherein n is 0 or 1; and wherein R3 is an alkyl group or aromatic group. |
