All Crestafix 621CC products provide a high shear strength bonded joints without the need for mechanical fixings.

 

Features and Benefits

  • Highly thixotropic: No drainage on vertical surfaces
  • Colour change system:Visual check for effective catalyst mix
  • Low shirnk system: No print through, excellent surface aspect
  • Urethane acyrlate base: Excellent adhesion and good elogation at break

 

 Application Properties

  • Geltime/ Working time for Crestafix 621 CC 45 at 25ºC for 100 g of bonding paste catalised with 3% by weight of  Luperx K1S or X-8 Catalyst: 22-28 min

  • Gap Filling: 1-25 mm

  • Colour Change: Blue/green to grey

 

Surface Preparation

The surfaces to be bonded should be clean, dry and free from any contamination. It may be necessary to mechanically abrade the surfaces to be bonded in order to obtain the bond strength required. Each surface should be coated with the catalysed bonding paste and held together until the adhesive has hardened.

 

Application

Crestafix 621CC are supplied pre-accelerated, requiring only the addition of catalyst to start the curing reaction. The recommended catalyst is Catalyst M (or Butanox M50 or other equivalent MEKP catalyst like Luperox K1S or X-8 Catalyst), which should be added at 1% to 2% w/v into the bonding paste. The catalyst should be thoroughly incorporated into the material with a low shear mechanical stirrer where possible, taking care to keep air entrapment to a minimum. Alternatively the bonding paste can be applied with a dispensing unit. The bonding paste, moulding and workshop should all be at, or above, 15°C before curing is carried out. Recommended temperature range for application is between 18°C and 25°C. The use of additional pigments or fillers is not recommended as they can affect the performance of the adhesive.For industrial/commercial use only. The user must determine the suitability of a selected adhesive for a given substrate and application. Contact your local Scott Bader representative for questions or assistance with the selection of adhesives for your use. This product is intended for use by skilled individuals at their own risk.
