Best Practices for Bostik Simson ISR 70-04
-
Surface Preparation
For good adhesion, a clean, dry and grease free surface is necessary. Cleaning of the ceramic coated layer can be done with Simson Prep M (a one step pretreatment) or Simson Cleaner I. The pretreatment with Prep M is also adequate for many closed surfaces like e.g. aluminum, coated steel, polyester (GRP). For more details concerning Prep M consult the specific technical information data sheet.
-
Application
ISR 70-04 can easily be extruded with a hand or air pressure gun at temperatures between +5°C and +35°C.
Within a few minutes after applying Prep M the screen can be bonded. The screen has to be bonded within 15 minutes after applying ISR 70-04. The drying time of Prep M can be reduced to seconds if a hot air blower is used. When no ceramic coating is available or the ceramic coating doesn’t supply sufficient UV-protection, Simson Prep G is needed after the screen has been cleaned with Simson Liquid 1 or Isopropyl alcohol, unless a cover shields the glass-adhesive interface from UV-radiation.
-
Clean-Up
Cleaning tools or removing uncured residue of ISR 70-04 can be done with a clean colourless cloth, wetted with Liquid 1 or Cleaner I. It is recommended to make a trial first to check possible attack of the substrate by these cleaners.
