ADS H155

ADS H155 is a medium molecular weight, solid polyvinyl acetate. It is designed for use in solvent based coatings, inks and adhesives or melt extrusion systems. ADS H155 can also be used as a low profile additive in unsaturated polyester composites, typically pultrusion and BMC processes.



Rapidly dissolves in most organic solvents including styrene

Can be melt processed

Easily plasticised

Can be combined with other M Grades

Excellent low profile performance in BMC & pultrusion processes


ADS H155 is manufactured on a dedicated polymerisation plant and is produced in the form of colourless beads.

Technical Informations

Application Advice/Typical Applications

Dissolving - ADS H155 is soluble in many organic solvents such as esters, ketones, aromatic hydrocarbons including styrene and lower alcohols. A more detailed list is available on the datasheet Solvent Solubility and Plasticiser Compatibility. ADS H155 should be added carefully to the solvent system under sufficient agitation to ensure dispersion of the polymer beads.
Melt - ADS H155 is thermoplastic and will gradually soften and flow with increasing temperature. Heat activated coatings and adhesives can also be easily formulated.
Compatibility - ADS H155 is compatible with other M Grade polymers, and can be mixed in any proportion to modify either solution or dry film properties. ADS H155 can be plasticised with many types of plasticiser to modify film properties. Further details are available on request.
