Crestafix 630PA is pre-accelerated vinylester based high performance bonding paste. It is a non-sagging, filled compound with high strength, specifically designed for the assembly and bonding of GRP mouldings. Such applications include panels, inserts, internal frames, ribs, internal core materials and composite constructions. Crestafix 630PA provides high shear-strength bonded joints without the need for mechanical fixings.
Features and Benefits
- Highly thixotropic: No sagging on vertical surfaces
- High strength: Replaces mechanical fasteners
- Vinyl ester based: Excellent adhesion and good elongation at break
- Geltime/ Working time for Crestafix 630PA with 2% by weight of catalyst Butanox LPT or Luperox K12G at 25ºC: 38-48 min
- Gap Filling: 1-25 mm (0.04-1.0 inch)
- Colour Change: None
Crestafix 630PA is suitable for use on GRP laminates, but also can be used on timber and plasterboard. However it is recommended that trials are carried out to ensure adequate bond strengths are obtained. Please contact Scott Bader Technical Services for information on other substrates and advice.
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. Please contact Scott Bader Technical Services for information on other substrates and advice.
Crestafix 630PA is supplied pre-accelerated, requiring only the addition of catalyst to start the curing reaction. The recommended catalyst is Butanox LPT-IN (or other equivalent catalyst), which should be added at 2% v/w 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. The bonding paste, moulding and workshop should all be at, or above, 15°C (59°F) before curing is carried out. Recommended temperature range for application is between 18°C and 25°C (64°F and 77°F). Each surface should be coated with the catalysed bonding paste and held together until the adhesive has hardened.
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. Recommendations contained herein are based on information we believe to be reliable. The properties and strength values have been obtained under controlled conditions at the Scott Bader laboratory.
As a rough guide, 3.3Kg (7.2lbs) of bonding paste will cover one square metre (10.76 ft2) to a depth of approximately 3mm (0.1 inch).
