DOW PARALOID B-48 Solid Thermoplastic Acrylic Resin

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.

Features Of DOW PARALOID B-48 Solid Thermoplastic Acrylic Resin

  1. Super Substrate Adhesion - Unique adhesion to hard - to - bond substrates such as untreated metals and glass, enabling stable film formation without primersDow Inc.

  2. Balance of Flexibility and Toughness - Excellent film toughness and flexibility, impact - resistant and not easy to crack, suitable for substrate deformation scenarios

  3. 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

  4. High - Gloss Film - Forming Property - High film gloss and stable color, improving the decorative effect and texture of the coating

Typical Applications Of DOW PARALOID B-48 Solid Thermoplastic Acrylic Resin

  1. General Metal Primers - Used for primers on untreated metal substrates, providing stable adhesion and basic protectionDow Inc.

  2. Automotive Refinish Paints - Suitable for automotive refinish coatings, with strong adhesion and good film toughness, matching the performance of original car coatings

  3. Glass Ink Binder - Serves as a binder resin for glass inks, with high film gloss and excellent adhesion to glass

  4. 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
