LOCTITE 435 is a rubber-toughened cyanoacrylate adhesive engineered for high-performance industrial bonding. This advanced formulation delivers exceptional flexibility and peel strength. Furthermore, it provides enhanced resistance to shock and impact, ensuring durable assemblies across various substrates. Its rapid curing properties streamline production processes.
General Information of LOCTITE 435
LOCTITE 435 utilizes an ethyl cyanoacrylate chemical base, functioning as a one-part system that requires no mixing. Atmospheric moisture initiates its curing process, leading to rapid fixture times. Consequently, this adhesive achieves full functional strength quickly, though complete chemical and solvent resistance develops over 24 hours. This ensures long-term durability in challenging environments.
This low-viscosity, colorless to straw-colored liquid is specifically designed for bonding metals, plastics, and rubbers. It also effectively adheres to porous and absorbent materials such as wood, paper, leather, and fabric. Its unique rubber-toughened formulation provides superior flexibility and peel strength. Furthermore, it significantly enhances resistance to shock and impact, making it ideal for dynamic applications. The product’s low viscosity allows for precise application in thin bond gaps, optimizing cure speed and bond integrity. LOCTITE 435 has undergone testing based on ISO 10993 biocompatibility standards, supporting its selection for medical device manufacturing.
