Document Type and Number:
Japanese Patent JP4001690
Kind Code:
B2
Abstract:
Polymerizable liquid silico-acrylic compositions comprising silica, a vinylsilane and tripropyleneglycol diacrylate. A transparent, liquid, water-white silico-acrylic composition which is: (i) stable upon storage; (ii) is heat- or radiation-polymerizable by a free radical mechanism; (iii) has a very low moisture content of less than 1.5 %, and (iv) has a very low content of volatile solvents. It comprises: (A) silica in the form of individual particles with a mean diameter of 5-100 (10-50) nm and which are not bonded together by siloxane bonds, (B) a vinylsilane of formula (I): H2C=CH-Si(OR)3 (I), in which: R = Me or Et; in an amount of 0.01-0.1 millimole per m<2> of the silica (A), and (C) tripropyleneglycol diacrylate (TPGDA). Independent claims are included covering: (a) a procedure for preparing the compositions and (b) use of the composition for forming transparent protective abrasion resistant coatings on a substrate.
