Synthomer H302

• Rapidly dissolves in most organic solvents including styrene
• High thickening efficiency
• Excellent solution stability
• No shrinkage
• High gloss

H302 is manufactured on a dedicated polymerisation plant and is produced in the form of colourless beads.

• Dissolving - H302 is soluble in many organic solvents such as esters, ketones and lower alcohols. H302 is however designed for dissolution in styrene. H302 should be added carefully to the solvent system under sufficient agitation to ensure dispersion of the polymer beads. Styrene solutions of H302 should be stored in appropriate air tight containers, and should incorporate an inhibitor to extend storage stability.
• Compatibility - H302 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 Synthomer M grades, H302 can be plasticised with many types of plasticiser to modify film properties.
• All types of SMC, BMC & Pultrusion

• 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 24 months from date of manufacture. Product which has been stored for longer than 24 months should be tested before use.
