Description

2-Propenoic Acid, Polymer With Butyl 2-Propenoate, Diethenylbenzene And Ethenylbenzene is a crosslinked acrylic copolymer engineered for high-performance binding, film formation, and structural integrity in demanding industrial formulations. This specialty polymer delivers exceptional mechanical stability, thermal resistance, and chemical resilience—making it ideal for applications requiring durable, solvent-resistant matrices. It is widely utilized by manufacturers of advanced coatings, pressure-sensitive adhesives, encapsulation resins, and functional composites across automotive, electronics, and industrial manufacturing sectors.

Application

• High-solids, low-VOC industrial coatings for metal and plastic substrates
• Pressure-sensitive adhesive (PSA) formulations requiring elevated shear strength and aging stability
• Encapsulation matrices for electronic components and sensors exposed to thermal cycling
• Binders in abrasive grinding wheels and ceramic green-body processing
• Reinforcing agents in thermoset composite systems (e.g., phenolic or epoxy hybrids)
• Stabilizing carriers for controlled-release agrochemical formulations
• Matrix material in radiation-curable inks and overprint varnishes
• Functional additives in high-performance sealants and gasketing compounds

Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards. Certificates of Analysis (COA) are available upon request. All batches conform to ISO 9001-certified manufacturing protocols and meet REACH registration requirements. Testing includes FTIR identity verification, gel content determination, Tg measurement (DSC), residual monomer analysis (GC), and viscosity profiling (Brookfield).

Storage

Preserve in a tightly closed container, protected from light. Store at room temperature (15–25°C) in a dry, well-ventilated area. Avoid exposure to moisture, strong oxidizing agents, and direct heat sources. Keep away from incompatible materials including strong alkalis and fluorides.
