Anti-ozonant
Advantages
– Sunprax is less soluble than paraffin waxes under normal temperature which allows immediate and continuous pro – tection for the rubber surface
– Coating will not break or crack at moderate elongation due to the flexible and closely – packed bloomed layer
– As a non-staining and non-coloring agent, Sunprax can be freely used for white and lightly colored compounds
Storage
– Keep the product at a well-ventilated area
– Store away from heat and moisture
– Keep away from sparks and flames
Shelf life
– 12 months
