Abstract:
Fluid silico-acrylic composition, which can be polymerised by heat and radiation, by a radical-type mechanism, with very low water (less than 1%) and volatile solvent content, containing silica, a silane and a multifunctional acrylic monomer, characterised by the fact that the silica is in the form of individualised particles, with a mean diameter of between 40 and 100 nm, not linked to each other by siloxane bonds, by the fact that the silane is a vinylsilane of formula (I)H2C&boxH;CHâ€”Si(OR)3â€ƒâ€ƒ(I) in which R represents a methyl or ethyl radical, and in that the multifunctional acrylic monomer is 1,6-hexanediol diacrylate, and by the fact that they are transparent, colourless and stable over time.
