Best Practices for Bostik Simson ISR 70-08 w/ 70-08A
-
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 "wash" Primer M (a one-step pretreatment) or Isopropyl alcohol. The pretreatment with Simson Primer M is also adequate for many closed surfaces like e.g. aluminum, coated steel, polyester (GRP). For more details concerning Simson Primer M, consult the specific technical data sheet.
-
Application
Bostik® 70-08A / Simson ISR 70-08 can easily be extruded with a hand or air pressure gun at temperatures between 41°F to 95°F (5°C to 35°C). The speed of application can be improved by heating up to 158°F (70°C) maximum.
Within a few minutes after applying Simson Primer M, the screen can be bonded. The screen has to be bonded within 15 minutes after applying Bostik® 70-08A / Simson ISR 70-08. The drying time of the ‘wash primer’ 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 Primer G is needed after the screen has been cleaned with Isopropyl alcohol, unless a cover shields the glass-adhesive interface from UV radiation.
-
Clean-Up
Cleaning tools or removing uncured residue of Bostik® 70-08A / Simson ISR 70-08 can be done with a clean colourless cloth, wetted with Isopropyl alcohol. It is recommended to make a trial first to check possible attack of the substrate by Isopropyl alcohol.
