Abstract
An aq. sizing compsn. for glass fibre strands contains, together with water, >0-90 wt.% of total solids of a polyvinyl acetate film former, 4-7 wt.% of fatty acid amide lubricant, 3-6% of gamma-ethylene diamine propyl trialkoxy silane and 2-6% of methacrylic acid chromic halide coupling agent, the composition containing 7-7.5 wt% solids and having been adjusted to a pH of 6.2-6.4. Used for forming into fibre glass roving for use in the spray-up process fibre glass reinforcement field. The noval forming size for the glass fibres is readily compatible with polyester resins, providing a superior gun roving prod.
