Abstract
Aqueous sizing compositions for glass fibers having emulsified epoxy resin as film-former, emulsified mineral oil as lubricant, glycidoxyalkyl and/or haloalkylsilanes as coupling agents, amide anti-static agent and polyvinylpyrrolidone give superior properties, especially where the sized glass fibers are used as reinforcement in epoxy resin articles, when reduced proportions of predominantly anionic surfactants are used to co-emulsify the epoxy resin film-former and the mineral oil.
