Bostik 70-08A AP is a high quality product based on Silyl Modified Polymer (SMP), especially developed for bonding windscreens. 70-08A AP provides a rapid and efficient way to fasten many different materials for OEM, coach works, mobile units, etc., especially where immediately or shortly after installation objects have to be moved during the manufacturing process. 70-08A AP conforms to FMVSS 212. 70-08A AP used with the Dual SMP® technology guarantees an increased and controlled cure speed and reliability in the production process and extends the application possibilities.
FEATURES
- High green strength
- Primerless adhesion
- Passes FMVSS 212 requirements for glass glazing
APPLICATIONS
- Adheres well without primer on glass and no UV blocking primer is needed when the glass-adhesive interface is UV-protected by a ceramic coating
- Solvent-, isocyanate- and PVC free
- Very good UV-resistance and aging properties
- Generally good adhesion on several substrates without the use of a primer
- Permanent elastic within temperatures from -40°F to 248°F (-40°C to 120°C).
- Neutral and odorless curing
- Low volume shrinkage
- Low electrical conductivity
