ABSTRACT:
An improvement in the method of preparing a glass-reinforced elastomeric product whereby cord blows may be eliminated. The method includes treating the glass fabric with a dip which improves adhesion to the rubber, and calendering the glass fabric and the rubber compound. The improvement comprises the step, prior to the calendering, of applying to the glass fabric an overdip composition including an effective amount of a material which is a cure accelerator for the rubber, whereby the amount of time required for full cure, and compaction of the rubber compound is reduced.
