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
150°C (302°F). 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.
