- Crestomer Advantage 30 is supplied ready to use in pre-packed 380ml co-axial cartridges with no hand mixing required. Crestomer Advantage 30 is supplied pre-accelerated and contains advantage catalyst within the cartridge. The mixer indicator system imparts a neutral, opaque white color and this blends well in cosmetically sensitive applications.
- For industrial/ commercial use only. The user must determine the suitability of a selected adhesive for a given substrate and application.

Technical Details & Test Data
- Comparisons with Competitive Materials
Crestomer® adhesives are one of a wide variety of materials that can be used in bonded assemblies. Compared to other adhesives, Crestomers offer the following benefits:
- Monomer type identical to polyester resins
- Cured with conventional peroxides
- Low exotherm during cure
- Available in a range of working and fixture times
- Ease of application
- Cost effective
High exotherm in an adhesive can cause the substrate to distort and give poor esthetic characteristics to the parts being bonded. The chemistry of Crestomer® adhesives ensures
that high exotherm temperatures, a characteristic of some other adhesives do not occur. The graph shows the exotherm temperatures of Crestomer® adhesives over a range of test temperatures.FRP to FRP bond strength
Exotherm of Crestomer® adhesives
High exotherm in an adhesive can cause the substrate to distort and give poor aesthetic characteristics to the parts being bonded.

The graph shows the exotherm temperatures of Crestomer® adhesives over a range of test temperatures.
- Surface Preparation
Crestomer Advantage 30 has excellent adhesion to FRP material provided that the surface has been maintained free of dust and grease. This can be guaranteed by the use of propietary stripable cloths such as peel ply (without lubricant contaminates). If the laminate surface is more than three days old it is recommended that they are lightly abraded and wiped with acetone or styrene on a lint-free, clean cloth prior to bonding.
