- Formulation Guidelines
- Crestapol 1260 should be allowed to attain workshop temperature before use. For curing at room temperature Crestapol 1260 requires the addition of a catalyst and an accelerator.
- N.B. Catalysts and accelerators should not be mixed directly together, since they react with explosive violence.
- The recommended catalyst for curing at room temperature is Trigonox 239, which should be added at 2% into the resin and thoroughly dispersed. The recommended accelerator is 1% solution of cobalt in styrene, which should be added at 2% into the resin and thoroughly dispersed.

Technical Details & Test Data
- UV Weathering Data
Panel Description
Laminate lay up as follows:
- 9” x 9” square
- 2 x glass tissue on tool side
- 2 x 450gsm powder pound CSM
- Peel ply and infusion flow media on bag side only
- Post Curing
Satisfactory laminates for many applications can be made using Crestapol 1260 by curing at workshop temperature. However, in common with all thermosetting polymers, optimum performance can only be achieved with a high temperature post cure.
- Abrasion Data
- Accelerated wear testing was performed by doing a Taber Abrasion test to ASTMD4060. After 4000 abrasion cycles, Crestapol 1260 lost 190mg.
- Impact Resistance Data
ASTM D 4226 Standard Test Method for Impact Resistance of rigid Poly Vinyl Chloride building products was conducted by Professional Engineering Inc. to determine what affect impact at extreme temperatures would have on the composite material. Tests to be conducted at -54°C/-65°F, ambient, and 71°C/160°F, on thirty samples at each temperature. All samples were conditioned for at least 24 hours then immediately tested to maintain the temperature of the test specimen. An 8.4lb weight was dropped from various heights to determine if the fibers broke in the composite material. For purposes of customer testing, the failure criteria would be no permanent deformation or breakage of the skin material. There was no permanent deformation or breakage observed.
