Description

Butyl Resin CAS NO 67351-93-3 is a synthetic polymer known for its excellent moisture barrier properties and strong adhesion to various substrates. This material is crucial for creating durable, flexible, and impermeable seals in demanding industrial environments. It is primarily needed by manufacturers in the adhesives, sealants, and protective coatings industries seeking reliable performance and long-term stability.

Application

• Adhesive Formulations: A key component in high-performance pressure-sensitive and hot-melt adhesives.
• Sealant Production: Used in construction and automotive sealants for its excellent water resistance and flexibility.
• Protective Coatings: Serves as a film-forming agent in coatings for metal, concrete, and fabric to provide corrosion and moisture protection.
• Caulks and Putties: Imparts durability and adhesion in industrial and marine-grade caulking compounds.
• Polymer Modification: Acts as a tackifier or modifier to enhance the properties of other elastomers and resins.
• Packaging Materials: Employed in laminates and coatings for flexible packaging to improve barrier performance.
