PENACOLITE Resins are resorcinol-formaldehyde condensation products used as adhesion promotors in tires and mechanical rubber products. Reinforcing materials such as rayon, nylon, fiberglass, polyester, steel, and aramid cords have all been successfully bonded to rubber with resorcinol-based adhesive systems. Other rubber products such as conveyor belts, power transmission belts, V-belts, and various pneumatic and hydraulic hoses also depend on resorcinol or resorcinol-derived bonding agents.

Compounding Resins
These resorcinol-formaldehyde resins can be substituted for resorcinol to augment adhesion of rubber skim stocks for brass-plated steel tire cord and various synthetic tire fabrics. They are thermoplastic and require a methylene donor, e.g. hexamethoxymethylmelamine (HMMM) or hexamethylenetetramine (hexa) to complete the reaction and become thermoset. These resins were specifically formulated to have low vapor pressures which substantially reduce the fuming and weight loss that occur with resorcinol at processing temperatures above 150C (302F). The adhesive bonds formed with Penacolite Resins in dry bonding systems are thermally stable and resistant to hydrolysis. They are supplied in pastille form, become molten at processing temperatures, and contain no free formaldehyde.

Dipping Resins
The liquid PENACOLITE Resins are designed for use in resorcinol-formaldehyde-latex (RFL) dip formulations for the treating of organic fibers such as polyester, nylon, rayon, or aramid. They can be used in place of resorcinol in RFL dip formulations without the need to age the resin solution as is required when using resorcinol. They contain no free formaldehyde, are stable, and will not polymerize during storage. The lower solids resins have low viscosities, making them ideal for automatic metering equipment and bulk purchases.
