ADS H301

ADS H301 is a medium / low molecular weight, solid polyvinyl acetate, developed for use as a thermoplastic low profile additive in unsaturated polyester composites. ADS H301 is a carboxylated polymer which achieves low solution viscosity, efficient compound thickening, very low shrinkage and excellent mould release.

 

FEATURES

Rapidly dissolves in most organic solvents including styrene

High thickening efficiency

Excellent solution stability and compatibility

No shrinkage

High gloss

 

ADS H301 is manufactured on a dedicated polymerisation plant and is produced in the form of colourless beads.

Application Advice/Typical Applications

Dissolving - ADS H301 is soluble in many organic solvents such as esters, ketones and lower alcohols. ADS H301 is however designed for dissolution in styrene. ADS H301 should be added carefully to the solvent system under sufficient agitation to ensure dispersion of the polymer beads. Styrene solutions of ADS H301 should be stored in appropriate air tight containers, and should incorporate an inhibitor to extend storage stability.
Compatibility - ADS H301 is compatible with other M Grade polymers, and can be mixed in any proportion to modify either solution or dry properties. In common with other M grades, ADS H301 can be plasticised with many types of plasticiser to modify film properties. Further details are available on request.


Very effective Low Profile Additive. All types of SMC, BMC, Pultrusion & RTM.

Shipping and Storage

ADS H301 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 H301 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.
