HV-3 Polyvinyl Acetate

Description

NiTCHEN HV-3 is a solid, thermoplastic homopolymer. It’s designed for use in solvent based coatings, inks and adhesives or melt extrusion systems such as automotive sound damping foils. It has the features of: rapidly dissolves in most organic solvents; can be melt processed; easily plasticised; can be combined with other grades; excellent adhesion to a wide range of substrates; very high light and thermal stability.

Application Advice

Dissolving – Nitchen pvac resin HV-3 is soluble in many organic solvents such as esters, ketones, aromatic hydrocarbons and lower alcohols. A more detailed list is available on the datasheet Solvent Solubility and Plasticiser Compatibility.  HV-3 should be added carefully to the solvent system under sufficient agitation to ensure dispersion and suspension of the polymer beads.

Melting – Pvac HV-3 is thermoplastic and will gradually soften and flow with increasing temperature. HV-3 can be used either alone or mixed with other HV-series polyvinyl acetate, in the formulation of automotive sound damping foils by compounding with appropriate pigments and plasticisers. Heat activated coatings and adhesives can also be easily formulated.

Compatibility – HV-3 is compatible with other FV-series polymers, and can be mixed in any proportion to modify either solution or dry film properties. HV-3 can be plasticised with many types of plasticiser to modify film properties. Further details are available on request.
