Product Description
LOCTITE PC 7210 is a two-component toughened epoxy repair paste for pipe, tank, and structural repair, including composite repair systems used with LOCTITE PC 5085 fabric. Resin and hardener mix at 100:55 by volume or 100:40 by weight and cure at room temperature after mixing. Typical data at 25 deg C include resin viscosity of 14,000 mPa s, hardener viscosity of 11,500 mPa s, and mixed specific gravity of 1.2. Typical working life is 30 minutes at 25 deg C and 20 minutes at 40 deg C. After seven days at 22 deg C, typical cured LOCTITE PC 7210 data include Shore D 77 hardness, a 100 deg C glass transition temperature, and 35 N/mm^2 lap shear strength on grit-blasted mild steel by ISO 4587.
Key features
- 100:55 Volume Mixing: The resin-to-hardener ratio is 100:55 by volume and 100:40 by weight.
- Temperature-Dependent Working Life: Typical working life is 30 minutes at 25 deg C and 20 minutes at 40 deg C.
- 35 N/mm^2 Steel Lap Shear: After seven days at 22 deg C, typical lap shear strength is 35 N/mm^2 on grit-blasted mild steel by ISO 4587.
Applications
Pipe, tank, and structural repair, including composite repair systems used with LOCTITE PC 5085 fabric.
