Crestapol® 1080 Urethane Acrylate Resin

Crestapol® 1080 Urethane Acrylate Resin

Crestapol 1080 is an exceptionally tough, flexible, unsaturated urethane acrylate in styrene monomer with a very high elongation. It is used to blend with other polyester and vinylester resins to create a much tougher resin formulation. Addition levels with other resin systems are typically in the region of 5-20%. Crestapol 1080 has been used in military applications, marine, tooling and many building projects requiring exceptional toughness.

Identification & Functionality


Features & Benefits


Crestapol 1080 has a high tolerance for fillers such as carbonates, talc, mica and barytes. It can be pigmented with an addition of up to 5% of Crystic Pigment Pastes.

Applications & Uses

Formulation Guideline

Crestapol 1080 has been formulated to give an adequate working time when cured with Catalyst M (Butanox M50) and Accelerator E. Curing should not be carried out at temperatures below 15°C. The resin and workshop should both be at, or above, this temperature.

Recommended Applications

Crestapol 1080 is extremely versatile, and will cure to a highly adherent, impact absorbing polymer. It can be formulated into adhesives and sealants for FRP (fibre reinforced polyesters), metal and ceramic substrates. It is particularly good where high impact resistance is required. Crestapol 1080 can be added to unsaturated polyester resins to improve flexibility, adhesion and impact resistance.

Packaging & Availability

Packaging Type
Crestapol® 1080 is supplied in 25Kg and 200Kg containers.

Storage & Handling

Shelf Life
6 Months
  • Crestapol® 1080 should be stored in the dark in suitable, closed containers. It is recommended that the storage temperature should be less than 20°C where practical, but should not exceed 30°C. Ideally, containers should be opened only immediately prior to use.
  • Extended storage at low temperatures may cause Crestapol® 1080 to crystallise out of solution. Warming for a short time above 35°C will bring it back into solution.
Pot Life

Crestapol 1080 has a typical pot life of 50 mins at 25°C with 2% Catalyst M (Butanox M50) and 4% Accelerator E.
