Description

Dianal Br-73 is a specialized acrylic-based resin designed for high-performance applications. This product is valued for its excellent film-forming properties, adhesion, and chemical resistance, making it a critical component in advanced coating formulations. It is primarily utilized by manufacturers in the paints and coatings, industrial adhesives, and specialty plastics industries seeking durable and reliable polymeric materials.

Application

• Industrial Paints and Coatings: Used as a key binder in high-durability metal coatings, automotive finishes, and protective industrial paints.
• Adhesives and Sealants: Serves as a primary resin in formulating structural adhesives, pressure-sensitive adhesives (PSAs), and construction sealants.
• Plastics Modification: Employed as an impact modifier or processing aid to enhance the toughness and weatherability of engineering plastics.
• Printing Inks: Acts as a vehicle resin in specialty printing inks, including overprint varnishes and packaging inks, for improved gloss and rub resistance.
• Textile and Leather Finishes: Provides a flexible, protective coating for synthetic leather, fabrics, and non-woven materials.
• Wood Coatings: Formulated into clear coats and pigmented finishes for furniture and flooring to offer scratch and stain resistance.
