HARDLOC is a two-part acrylic adhesive developed by DENKA and classified as a second-generation acrylic adhesive (SGA). Because of its excellent adhesive qualities and long durability, HARDLOC has been successfully applied in various fields, including loudspeakers, transformers, motors, and other electrical components, elevators, automobiles, metal cabinets, construction metals, etc.
HARDLOC SGA G-53-05 with excellent heat resistance and high elastic modulus is usually used in porous surface bonding applications in loudspeakers.
FEATURES:
- Rapid curing at room temperature
- Excellent shear peeling and impact resistance
- Allow bonding of oily surfaces
- Allow bonding of different materials
- Allow bonding with a rough 2K materials
- Solventless adhesives
RECOMMENDED APPLICATIONS:
- Porous Substrate
- Loud-speaker assembly
