Polyvinyl Acetate Emulsions & Derivatives (PVAc) for Adhesives and Sealants

Vinavil® PW195 by Vinavil is a 50% modified polyvinyl acetate aqueous dispersion. It is used in combination with VINADUR 500 or VINADUR 100 for making two-component wood adhesives specifically designed for plywood panel manufacturing. It is suitable for light wood (poplar, okoume) and higher density wood (beech, birch, eucalyptus, sapelli) and is particularly well suited to high-frequency and/or pre-pressing gluing cycles.

• 2k adhesive based on Vinavil® PW195 does not require specific crosslinking temperature to accomplish the final panel bond strength.
• It is easy to handle and offers fast setting compared to UF and soy protein technologies.
• It reduces pressing and converting time, enhancing productivity.
• It provides long pot life stability (up to 5 days) and can be stored at temperatures between 5 and 40°C.
• It enables the production of panels class 1, according to EN717-1 and EN 314 (class 2 achievable under specific application conditions), and are compliant to CARB NAF certification.
• It has a shelf life of 6 months.
