Designed with patented methyl methacrylate technology, Bostik’s SAF structural adhesive product line offers unmatched chemical, environmental, mechanical and fatigue resistance for many industrial applications. Able to bond a wide range of dissimilar substrates, including composites, metals and plastics, the SAF product line features high elongation from 30-250%, smart viscosity formulation, minimal surface preparation and a wide range of open and curing times.
FEATURES
Long open and fixture times, cure time of approximately 120 minutes
Non-sag application on vertical surfaces
Excellent environmental resistance
APPLICATIONS
The optimum quality is obtained at room temperature, ideally between 64 – 82°F (18 – 28°C) without post-curing.
Follow the instructions on the product operating guide or contact your Bostik representative for any information concerning product use or dispensing equipment.
