Abstract: Transparent substrates are rendered resistant to fogging by the application of a hardcoat composition comprising finely divided silica, a multi-functional olefin containing two or more olefinic moieties and one or more divalent oxyalkylene radicals having the formula:--((CX.sub.2).sub.n O).sub.x ((CX.sub.2).sub.m O).sub.y --where the sum of the x stoichiometric subscripts for each divalent oxyalkylene radical and the sum of the y stoichiometric subscripts for each divalent oxyalkylene radical when said sums are added together is ten or greater and the stoichiometric subscripts n and m are different and have values independently ranging from one to ten, where each X is independently selected from the group consisting of hydrogen, one to forty carbon atom monovalent hydrocarbon radicals and six to forty carbon atom monovalent aromatic hydrocarbon and an olefinically functionalized trialkoxysilane followed by curing.
Abstract: The present invention relates to a method for making nitrosamine-free silicone articles by treating the mixture of vinyl containing organopolysiloxane and filler with hindered phenols, a nitrosamine-free composition and a nitrosamine-free article made therefrom. A preferred nitrosamine-free molded article is a baby bottle nipple.
Abstract: One component room temperature vulcanizable silicone sealant compositions comprising both a specific cross linker, ethyltriacetoxysilane, and a specific extending filler, stearic acid treated calcium carbonate, exhibit an extended work life or tooling time.
