Responding to global environmental regulations such as REACH! For bonding in automobiles and electronic devices with restrictions on the use of heavy metals! *Product catalog giveaway.

Sharp Chemical Industries' new product, Metal-Free Bond, is an elastic adhesive that does not use heavy metal catalysts such as tin or titanium. It is a fast-curing type, allowing for quick transition to the next process. It excels in acid and alkali resistance compared to our conventional products, making it suitable for areas that require repeated cleaning. It complies with global environmental regulations such as REACH (European Chemicals Regulation), making it ideal for industrial fields like automotive, electronic materials, and construction, where the use of heavy metal compounds is restricted. 【Features】 ■ Can seal and bond materials with different thermal expansion rates! ■ Suitable for filling and bonding uneven substrates and surface materials! ■ Good adhesion to engineering plastics like PC and PA, which are difficult to bond with metals like aluminum and stainless steel! ■ Paintable unlike silicone! 【Applications】 ■ Bonding and sealing of speakers and measuring instruments where vibration control is necessary ■ Waterproof sealing for automobiles, train vehicles, containers, forklifts, etc. ■ Waterproof sealing for electrical devices that dislike silicone components

Applications/Examples of results

- Adhesives required for environmental compatibility in industrial fields with heavy metal catalysts - Sealant adhesion for materials with different thermal expansion rates - Filling adhesion for substrates and surface materials with irregularities - Sealant adhesion for areas with significant temperature fluctuations

Detailed information

Usage Example 1 Metal-free bond has excellent alkali resistance and can be used in areas subjected to repeated washing. Since it does not contain metal catalysts, reversible reactions are suppressed, and its chemical resistance to alkalis and other substances is improved compared to conventional products. It can also withstand slightly stronger commercial cleaning agents. Suitable for waterproof seals in automobiles, train vehicles, containers, forklifts, etc.
Application Example 2 An elastic adhesive ideal for areas where vibration suppression is necessary, such as speakers. Viscosity design tailored to the device is also possible. It can be used for sealing and bonding materials with different thermal expansion rates, as well as for sealing and bonding in areas with significant temperature changes.
