Estimating the term…
A sulfur-crosslinkable adhesive composition of the non-aqueous type, that is to say not requiring the presence of water, usable for direct bonding of a pregelled polyester or vinyl ester composite to rubber in the uncured state. The composition comprises polyvinylpyridine-styrene-butadiene elastomer (“p-VSBR”) in combination with a polyester or vinyl ester resin. Preferably, the resin used is a novolak and/or bisphenol based resin of the epoxy vinyl ester type. This composition, unlike conventional RFL adhesives, does not require any activation treatment, such as intermediate drying, at the time of use. A process for preparing such an adhesive composition, use of said composition for the manufacture of laminated composite parts.
A sulfur-crosslinkable non-aqueous liquid adhesive composition comprising at least a polyvinylpyridine-styrene-butadiene elastomer (abbreviated to “p-VSBR”), a polyester or vinyl ester resin, less than 2% water, and between 5% and 35% of a resin solvent, based on the weight of the adhesive composition.
A laminated part comprising at least one layer of polyester or vinyl ester composite connected to a layer of diene elastomer, the connection between the two layers being provided by a non-aqueous liquid adhesive composition based on p-VSBR elastomer and polyester or vinyl ester resin.
A sulfur-crosslinkable non-aqueous liquid adhesive composition comprising at least a polyvinylpyridine-styrene-butadiene elastomer and a polyester or vinyl ester resin.
