LOCTITE® HY 4080 GY is a 2-part, grey, cyanoacrylate/acrylic hybrid structural adhesive providing toughness and excellent adhesion to metals, composites and plastics. It provides fast fixture at room temperature and high operational strength within the first hour. It has good resistance to peel and impact loads while maintaining high shear strength over a wide range of temperatures and larger gaps. Best application results are achieved with LOCTITE® 50 ml Adhesive Mixing Nozzle (IDH 1826921), LOCTITE® 400 ml Adhesive Mixing Nozzle (IDH 1573135), LOCTITE® 96001 (IDH 267452) or LOCTITE® 983439 (IDH 218311).
- High viscosity (thixotropic)
- Good resistance to peel and impact loads while maintaining high shear strength
