Sunprax

Application Sunprax will effectively protect the surface cracking of rubber products from the sunshine, ozone and the frosting(or solidity) from the moisture in the air. Characteristics Being less soluble than general paraffin waxes at the normal temperatures, Sunprax will immediately and continuously provide the protective layer on the rubber surface during exposed to sunshine and ozone. As this bloomed layer being flexible and closed packed, it cannot be broken and cracked at moderate elongation. As non-staining and non-coloring agents, Sunprax can be used freely to white or light coloured compounds.
