Catalytic Epoxy system with 10:3 weight ratio, dedicated to vacuum formed construction to realize prototypes and competitive products where sturdiness and lightness are determining for all work where long pot life (working times) and very high mechanical performances are required
It has a pot-life up to 6 hours (with ambient temperatures of about 20°C) and can be applied wet on wet for up to 24 hours. The first drying occurs in 48 hours and afterwards it needs to be baked at least at 60°C to achieve perfect cross-linking. In order to obtain this value it is necessary to put the product in the kiln and to increase the temperature by 10°C over each hour until the desired temperature is reached, and then to leave it for at least 2 hours at the maximum temperature. Cool it down slowly taking it back to ambient temperature.
For particularly complex and heavy or mass constructions the warming-up times can be adjusted, extending them according to the needs and in order to get the perfect “baking” temperature all through, and it distributed in a uniform manner without causing surface temperature differences.
C-Systems’ 10 3 with the seal U.V. and SL. present out-standing mechanical properties also when hardening in ambient temperatures between 20 and 25° C.
C-Systems’ 10 3 U.V. and 10 3 SL. show a noticeable cross-linking capability also at low temperatures. These types of catalysts are suitable for manual repairs, works and impregnation of light composite products using fibreglass, kevlar and carbon fibre .
10 3 U.V. The 10 3 resin with hardener U.V. proves to be an epoxy mixture with medium reactivity with a thin film open time of 2 to 3 hours, indicated for products which have to withstand U.V. rays and yellowing.
Nevertheless, it is advisable to finish the product with a paint with added anti U.V. and yellowing filters.
10 3 SL. The 10 3 resin with SL hardener has a thin film open time of 3 to 4 hours with the best thermal performances and average usage time. It is indicated for vacuum bag impregnations of medium sized products (30-50 square metres). At temperatures from 20 to 25° C C-Systems’ 10 3 with U.V. or SL seal can noticeably improve its thermal resistance with post-hardening cycles at moderate temperature (e.g. after 7 days at 25° C a thermal resistance of 58° C is achieved while by applying heat afterwards for 15 hours at 60° C a thermal resistance of 90° C is achieved). This allows the realization of large surface composites with a limited deformation risk even without positioning on the mask during post-hardening, as the products’ thermal resistance is always higher than the applied temperature.
-A potential thermal resistance up to 130°C allows the realization of post-hardened products at moderate temperatures which are though going to improve their thermal resistance without collapsing in critical situations (like super light aircrafts or black products with surface temperature of even 80°C).
