ABSTRACT 38
Based on the proposed chemical mechanism of precipitated silica enhancement of
brass-coated wire-to-natural rubber adhesion, statistically designed compounding
. U4 Z( N$ h% z9 ^6 L* texperiments were developed in order to optimize composite performance of a wire coat
compound containing an organocobalt adhesion promoter. Compound cure, and cured
compound physical and adhesive properties are examined. Energy of adhesion (a)
values for original and heat-, humid- and salt-aged specimens were determined from
- s, Q1 K) d; r  A/ d0 l, xtire cord adhesion test (TCAT) measurements. Improvements in original and aged
adhesive energy and rubber coverage values are obtained in the optimized system. A
wire coat compound containing silica (Hi-Sil®233), organocobalt and a
% |# W2 X6 z% j3 b: t( H0 m/ @resorcinol/formaldehyde donor resin system is also studied. Results are compared to
those based on wire coat formulations of tire manufacturers using specialized
