Fasteners with adhesive coating

Reactive system (adhesive systems)

• Microencapsulation - DIN 267, part 27
  Complete coating of microencapsulated adhesive, which is activated by the screwing-in process and counteracts self-unscrewing after hardening.

Examples of use

• Precote 30-3
• Precote 80
• Scotch-Grip

Coating method

• Manual or mechanical
• Flowing, dripping
• Wave soldering

Viscosity control

• DIN cup

Product features (finished product, hardened adhesive)

• Reaction time when installed:
  24-72 hours at RT
  15-30 mins at 70°C

• Lock against self-loosening
• Vibration-proof
• High breakaway torque MLB/MA > 0.9
• Resistant to oils, grease, fuels
• Fail-safe from -30°C to 150°C
• Low coefficients of friction (product-specific)

Lubricated surfaces

• In the case of surfaces with integrated and/or additionally applied lubrication, the specified requirements must be met at room temperature.

• At higher temperatures, these values do not have to be met. The additional locking effect of the adhesive must be verified in a comparative test. The values of the MK-coated screws must be greater than the values of uncoated screws.
