Improved method for gluing one or more strands of glass-resin composite, grc

A process for sizing one or more strands of glass-reinforced plastic comprising the following steps:

• (a) pre-bonding one or more strands of glass-reinforced plastic by dipping the one or more strands in a first aqueous bath comprising a composition based on:
• an epoxy compound;
• and
• a blocked diisocyanate compound;
• and
• (b) depositing on the glass-reinforced plastic by dipping the one or more strands in a second bath comprising an aqueous adhesive composition based on:
• at least one compound A1, the compound A1 comprising at least one aldehyde function;
• at least one phenol A21;
• and
• at least one unsaturated elastomer latex comprising at least one elastomer selected from the group consisting of butadiene copolymers, styrene-butadiene copolymers, vinyl pyridine-styrene-butadiene terpolymers, natural rubber, with the exception of chlorinated natural rubber, and mixtures thereof,
• wherein a content of blocked diisocyanate compound in the aqueous adhesive composition of the second bath is at a weight content of less than 0.50%.
