Description

Poly(Isobutylene-Alt-Maleic Anhydride) is a high-performance alternating copolymer known for its excellent film-forming and adhesive properties. This versatile polymer is crucial for creating durable, water-resistant coatings and enhancing the performance of various industrial formulations. It is primarily sought after by manufacturers in the adhesives, coatings, and oilfield chemical industries for its ability to modify rheology and improve product stability.

Application

• Adhesive & Sealant Formulations: Acts as a key tackifier and rheology modifier in pressure-sensitive adhesives and construction sealants.
• Industrial & Protective Coatings: Used in water-based and solvent-based coatings to enhance corrosion resistance, adhesion, and film integrity.
• Oilfield Chemicals: Serves as a scale inhibitor and dispersant in drilling fluids and production chemicals.
• Paper Sizing & Treatment: Improves water repellency and strength in paper and paperboard products.
• Textile Finishing: Employed as a binder and finishing agent to impart durable-press and water-repellent properties to fabrics.
• Detergent & Dispersant Additive: Functions as a dispersing agent and anti-redeposition aid in industrial and institutional cleaning formulations.
