DOW Chemical B - 67 is a highly hydrophobic solid thermoplastic acrylic resin in the PARALOID series, designed for alkyd modification and water - resistant coating. It is bead - like particles with 100% solid content, being the model with outstanding water resistance in the PARALOID™ series. It has excellent pigment dispersibility and is compatible with medium and long - oil alkyds, drying oils, oleoresinous varnishes, etc
Super Hydrophobic and Water - Resistant - Outstanding water resistance in the PARALOID™ series, the coating is not easy to blister and fall off, suitable for humid environments
Efficient Pigment Dispersion - Excellent dispersibility, ensuring uniform distribution of pigments and improving the color stability and gloss of the coating
Alkyd System Compatibility - Compatible with medium and long - oil alkyds, drying oils, oleoresinous varnishes, etc., helping to improve coating hardness and drying speed
Stable and Durable Film Formation - The formed film is yellowing - resistant, with good color and gloss retention, not easy to lose luster and change color after long - term use, extending the service life of the coating
Alkyd Resin Modification - Used for medium and long - oil alkyd modification to improve coating drying speed, hardness and yellowing resistance
General Industrial Finishing - Suitable for substrates such as metals, plastics and wood, providing both decorative and protective effects
Vacuum Metallizing Topcoat - Used for surface finishing of vacuum metallized parts to improve surface gloss and weather resistance
Wood Water - Resistant Coating - Used for outdoor wood products to enhance water - resistant and moisture - proof performance and extend service life
