  • Best Practices for Bostik 8104

    *See Terms of Use Below

    1. Application

      Apply by roller coater, hand brush, or spray at the rate of 100-140 grams per square meter.

    2. Curing

      Dry approximately 4-5 minutes at 63-85°C (145-185°F). Heat activate under pressure (vacuum) at a bond line temperature of 43-85°C (109-185°F) within 60 minutes after drying. Maximum hot bond strength develops after 72 hours.

    3. Clean-Up

      Water while wet, MEK for dry adhesive
