利用烷基三氯硅烷封端双羟基PDMS,再将其与羟基丙烯酸树脂反应,将PDMS化学键合至丙烯酸树脂链段上,然后与异氰酸酯固化剂固化得到排液自洁涂层。
Using alkyl trichlorosilane to block the double hydroxy PDMS, it is then reacted with hydroxy acrylic resin to chemically bond the PDMS onto the acrylic resin segment, and then cured with isocyanate curing agent to obtain a self-cleaning coating for drainage.
