Description

2-Propenoic Acid, 2-Methyl-, Polymer With Butyl 2-Propenoate, Ethyl 2-Propenoate And Methyl 2-Methyl-2-Propenoate, Ammonium Salt is a high-performance, water-based acrylic copolymer dispersion designed for superior film formation and adhesion. This versatile polymer is valued for its excellent binding properties, water resistance, and stability across a wide pH range. It is an essential raw material for formulators in the coatings, adhesives, and construction industries seeking durable and environmentally compliant solutions.

Application

• Architectural Coatings: As a primary binder in interior and exterior paints, providing scrub resistance, durability, and low VOC formulation capability.
• Industrial Coatings: Used in protective and decorative coatings for metal, wood, and plastic substrates, offering good corrosion resistance and weatherability.
• Adhesives & Sealants: Serves as a key component in pressure-sensitive adhesives (PSAs), construction adhesives, and caulks, delivering strong tack and cohesive strength.
• Textile & Nonwovens: Functions as a binder and finishing agent for fabrics, imparting stiffness, hand feel, and wash-fastness.
• Paper & Paperboard Coating: Enhances surface strength, printability, and water resistance in coated paper and packaging materials.
• Leather Finishing: Used in topcoat formulations to provide a flexible, protective, and glossy finish.
• Construction Chemicals: Incorporated into cementitious modifiers, tile adhesives, and waterproofing membranes to improve flexibility and bond strength.
