What is BOSTIK ISR 70-08 AP BLACK and why choose it?
BOSTIK ISR 70-08 AP BLACK is a high-quality, silane-modified polymer (SMP) elastic adhesive designed for direct glazing, automotive windscreen replacement and general bonding and sealing in mobility applications. It offers very fast strength build-up, excellent initial grab and outstanding UV, weather and temperature resistance. Thanks to its primerless adhesion on glass and many industrial substrates and its compliance with FMVSS 212 (safe drive-away time of 45 minutes when correctly used), it is ideal for professional vehicle glazing and window bonding operations.

Adhesion and substrate preparation
- Adheres well without primer to most clean, dry, dust- and grease-free substrates.
- On glass with ceramic coating/frit: clean thoroughly with Bostik Cleaner I before applying the adhesive.
- On glass without ceramic coating, or where the coating does not provide sufficient UV protection: Bostik Prep G plus is mandatory to protect the adhesive bond line from UV exposure.
- No adhesion is obtained on untreated polyethylene, polypropylene and PTFE (Teflon).
- For high thermal or mechanical loads, especially in wet conditions, use Bostik Prep CS or Prep M (TF) to degrease and prepare the surface in one step.
- On plain, untreated wood and other porous substrates, pre-treat with Bostik Prep P.
Application guidelines
- Apply BOSTIK ISR 70-08 AP BLACK using a manual or pneumatic gun between +5°C and +35°C.
- In bonding applications, assemble substrates within 15 minutes of adhesive application at 23°C / 50% RH.
- Recommended minimum adhesive thickness: 2 mm.
- Tool or profile the bead within 15 minutes (23°C / 50% RH) with a spatula or putty knife lightly moistened with an aqueous soap solution.
- Avoid soap solutions containing limonene, as they can cause sealant discoloration.
- Prevent soap solution from penetrating between joint sides and adhesive to avoid adhesion loss.
- Clean tools and uncured excess adhesive with a clean, colourless cloth moistened with Bostik Liquid 1.

FAQ – BOSTIK ISR 70-08 AP BLACK
-
Is BOSTIK ISR 70-08 AP BLACK classified as hazardous?
No. According to Regulation (EC) 1272/2008 [CLP], this mixture is classified as not hazardous. However, it contains Trimethoxyvinylsilane, which may cause an allergic skin reaction (EUH208), and small amounts of methanol are released during curing.
-
Do I need a primer on glass?
For glass with ceramic coating/frit, thorough cleaning with Bostik Cleaner I is required, but no primer is needed. For glass without ceramic coating or with insufficient UV protection, Bostik Prep G plus is mandatory to protect the adhesive bond line from UV radiation.
