A typical resorcinol/formaldehyde/latex (RFL) adhesive and two modified versions were used to bond a tire body stock (NR/SBR/BR blend) to polyethylene terephthalate (PET) cord. Modifications contained a commercial chlorophenol/resorcinol condensate or a lab‐prepared chlororesorcinol/resorcinol condensate (CRA). Standard H‐test specimens were prepared by embedding adhesive‐coated, heat‐treated cords into the rubber and then vulcanizing. The effect of heat treatment time and overcure on pull‐out adhesion was studied. Overcure conditions were used to simulate long service. Pull‐out forces increased with longer heat treatment and decreased with overcure. The CRA‐modified adhesive gave the highest pull‐out forces after overcure. © 2003 Wiley Periodicals, Inc.
