ADS H302 is a medium / high molecular weight, solid polyvinyl acetate, developed for use in unsaturated polyester composites. ADS H302 is a carboxylated polymer which achieves efficient compound thickening, very low shrinkage and excellent mould release.
Rapidly dissolves in most organic solvents including styrene
High thickening efficiency
Excellent solution stability
ADS H302 is manufactured on a dedicated polymerisation plant and is produced in the form of colourless beads.
ADS H302 is a thermoplastic solid. To prevent sticking of the polymer beads the product should be stored in dry conditions, below +20 °C (+68 °F) out of direct sunlight. Pallets should not be stacked. Under these conditions the product has a storage life of at least 12 months from date of delivery. Product which has been stored for longer than 12 months should be tested before use. ADS H302 is supplied in 25kg paper sacks each marked with the grade reference and batch number. The minimum order quantity is 1000kg on a stretch wrapped pallet.
