Technical Data Sheet
Crestapol
1260
Crestapol
1260 is a low viscosity urethane acrylate type resin which is suitable for infusion, Resin Transfer
Moulding (RTM) and similar processes at room temperature, and can be infused at vacuum levels down to
-1.0 Bar. Crestapol 1260 produces laminates with high strength and toughness with exceptional water and
hydrolysis resistance.
Excellent mechanical performance and durability
using only moderate temperature post-curing cycles
High temperature performance – HDT 109 C/ 228

Compatible with carbon fibre reinforcement
materials and general purpose sizing agents
Ability to vary cycle time eliminates the need
to stock different resin grades
Standard 30 minute gel time but also available
in 60 and 90 minute gel times
KEY FEATURES OF CRESTAPOL
1260
INTRODUCTION
FORMULATION
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.
POST CURING
Satisfactory laminates for many applications can be made using Crestapol 1260 by curing at workshop tem-
perature. However, in common with all thermosetting polymers, optimum performance can only be achieved
with a high temperature post cure. The typical cure time can be found inside our Crestapol Information Guide.

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
o
C/ -65 F, ambient, and 71
o
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 fibres 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.
