DOW Chemical B-48N is a high-adhesion solid thermoplastic acrylic resin in the PARALOID™ series, designed for unprimed metal and glass coatings. It is bead-like particles with 100% solid content, being the model with excellent balance of adhesion and flexibility in the PARALOID™ series. It has strong adhesion to hard - to - bond substrates such as untreated metals and glass.
Super Substrate Adhesion - Unique adhesion to hard - to - bond substrates such as untreated metals and glass, enabling stable film formation without primersDow Inc.
Balance of Flexibility and Toughness - Excellent film toughness and flexibility, impact - resistant and not easy to crack, suitable for substrate deformation scenarios
Boiling Water and Aging Resistance - Good boiling water resistance and strong outdoor durability, the coating is not easy to blister and fall off after long - term use
High - Gloss Film - Forming Property - High film gloss and stable color, improving the decorative effect and texture of the coating
General Metal Primers - Used for primers on untreated metal substrates, providing stable adhesion and basic protectionDow Inc.
Automotive Refinish Paints - Suitable for automotive refinish coatings, with strong adhesion and good film toughness, matching the performance of original car coatings
Glass Ink Binder - Serves as a binder resin for glass inks, with high film gloss and excellent adhesion to glass
Hard - to - Bond Substrate Protection - Used for the protection of hard - to - bond substrates such as plastics and ceramics, solving the problem of poor adhesion
