Applications
Uses: Nochek® 4729A wax, when used as the sole protectant, finds wide usage in nonstaining rubber parts which must have good exterior durability. These include mechanical goods, automotive parts, footwear, heels, soles and tire white sidewalls. Nochek® 4729A wax is used extensively with chemical antiozonants in applications requiring a maximum degree of mixed static-dynamic ozone exposure protection. Typical uses include conveyor belts, industrial hose, jacketing and insulation for electrical wire and cable, treads and black sidewalls for a variety of
tire types.

Protection: Blended microcrystalline/paraffin wax with a melt point of 66-69°C (151-156°F).
Provides static ozone protection through formation of a thin continuous wax layer (bloom) on the surface of the rubber. Microcrystalline structure provides more controlled rate of bloom than straight paraffin structure. Nochek® 4729A has the broadest range of protection any blended
wax, providing protection in both low and high temperature applications.

Synergism: Synergistic with p-phenylene diamine (PPD) antidegradants for maximum static and dynamic ozone protection.

Staining: Non-staining. Can be used in white
compounds.

Cure Effect: No effect
