Bostik 7500 series epoxy systems are 2-part, room temperature curing structural adhesives designed to provide exceptional flexibility for many applications. These unique formulae have been engineered with a range of properties to deliver the performance to match your unique and demanding requirements for construction, repair, MRO or product assembly applications.
c Unlike conventional 5-minute epoxies, Bostik 7575 is designed for structural bonding applications requiring a fast-setting epoxy with low shrinkage, good shock resistance and excellent mechanical and electrical properties. It provides superior resistance to vapors, gases, water, galvanic action, petroleum fuels and salt solution. Unique formula also allows for exposure to moist or damp surfaces while bonding. 7575-Clear is an excellent choice for a variety of applications including potting, encapsulation, sealing electrical components and for many quick repairs.
