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.

BENTONE® EW by Elementis is a rheological additive for waterborne system. It is a highly beneficiated, easily dispersible smectite clay. Provides thermostable aqueous phase viscosity control and promotes fast water release. Imparts thixotropy and enhances texturing and stippling effects. Prevents hard settlement of pigments/ fillers and reduces syneresis. It offers excellent sag stability & slump control, outstanding workability and high amount of elasticity. It minimizes floating and flooding of pigments. BENTONE® EW is designed for adhesive applications. It is suitable for the formulation of acrylic sealants. Recommended dosage level is 0.1-1.0%. It has a shelf life of 4 years from the date of manufacture.

BENAQUA® 4000 by Elementis is a polymer modified clay-based rheological modifier. It is an easily dispersible powder designed for water-borne, ready mixed & powder adhesives, mastics and sealants.

• It provides excellent suspension and high viscosity in the low to medium-shear-rate region.
• Offers superior sag resistance at low package viscosity compared with conventional thickeners as well as improved shear-thinning rheology.
• It has good storage stability at elevated temperature, freeze/thaw stability and enzyme resistance.
• It gives very good suspension, efficient spray atomization, minimized mud cracking, enhanced textured and stippling effects.
• The recommended dosage level is 0.3-2.0% by weight.
• BENAQUA® 4000 has a shelf life of 2 years.

RHEOLATE® 175 by Elementis is hydrophobically modified alkali-swellable emulsion (HASE) rheological additive. It is an easy-to-use emulsion form designed to provide excellent mid- to high-shear viscosity build.
