CYCOM 823 RTM Epoxy System

CYCOM 823 RTM is a liquid epoxy resin system. It is primarily available as a 1 part system, with one working week out-life at room temperature so as to remove the requirement for customers to carry out resin mixing and its associated quality control processes.

Its frozen storage shelf-life is 6 months at 0ºF/-18ºC. If extended ambient storage is required then the resin could be supplied as a two-part system.

CYCOM 823 RTM’s viscosity is low enough at room temperature to allow injection without having to heat either the resin or the transfer pipework. When the resin is heated to the cure temperature its viscosity is further reduced, helping to ensure full wet-out of the reinforcing fibres.

CYCOM 823 RTM is fully cured after 1 hour at 255ºF/125ºC giving a continuous dry service performance of 230ºF/110ºC, and a continuous hot/wet service performance of 195ºF/90ºC.

For reinforcement preforming operations a fully compatible binder system, CYCOM 790 RTM, has been developed for use with CYCOM 823 RTM. The binder is available pre-coated onto fabrics of the customers choice.
