Crestapol® 1261 is a high performance low viscosity urethane acrylate type resin to work with Carbon Fibre, Glass or any other reinforcement types, suitable for infusion, RTM and similar processes at room temperature.

Crestapol® 1261 produces laminates with high strength and toughness with exceptional water and hydrolysis resistance.

Formulation

Crestapol 1261 should be allowed to attain workshop temperature before use. For curing at room temperature Crestapol
1261 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 Accelerator G1, which should be added at 2% into the resin
and thoroughly dispersed.


Post Curing

Satisfactory laminates for many applications can be made using Crestapol 1261 by curing at workshop temperature.
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.
Physical Data – Uncured
The following tables give typical properties of Crestapol 1261 when tested in accordance with BS2782.

The gel time fr this resin at room temperature of 20 ºC is 40-50 min at 25°C with 2% Accelerator G and 2% of catalyst Trigonox 239. Accelerator G is a 1% solution of cobalt in styrene.

Storage

Crestapol 1261 should be stored in the dark in the original container. It is recommended that the storage temperature
should be less than 20°C, but should not exceed 30°C. Containers should be stored out of direct sunlight and away from
other external sources of heat. Ideally, containers should be opened immediately prior to use.

ADR (DANGEROUS GOODS)

Some products will be considered dangerous goods (ADR) when their container exceed certain amounts. ADR products must be transported by special transport agencies, such as SCHENKER or TXT.

* The following products will be considered ADR (Dangerous Goods) when their container EXCEED the values shown in the table below. Products of equal or smaller size than those shown will not be considered ADR, so they may be transported also by SEUR and Envialia.

_____________________________________________________________

If you have selected a product whose container size is considered ADR and you choose SEUR or Correos EXPRESS as carrier, those ADR products will be transferred into smaller containers to not breach the European Agreement concerning the International Carriage of Dangerous Goods by Road. That is, if you order a 25 kg resin drum and you select SEUR or Correos Express as carrier because you need the products sooner, the resin will be supplied in 5 containers of 5 kg each and its catalyst will be supplied in 5 containers of 100 g.

In any case, drums bigger than 25 kg must be shipped by TXT or Schenker.

* Shippings to Portugal will be always carried by Torrestir
