RESOLTECH 1800 Hardeners 1805 & 1808 Structural Epoxy system for infusion & injection Adjustable pot life from 1h to 2h Very low viscosity and high wetting power TG: 85º to 130º depending on hardener used Excellent cross linking properties even at low post-curing temperatures RESOLTECH 1800 is an advanced infusion and injection epoxy resin system with an extremely low viscosity for fast and safe wetout by infusion and injection. It features high mechanical properties, a TG of up to 130°C and up to 5H30 of infusion or injection time. A great property of the system is its constant low viscosity right until gel time. It therefore offers reliable impregnation and air release throughout the infusion or injection process. Suitable for very large composite parts. This system has excellent cross linking properties and enables to obtain a high TG of 130ºC even at low post curing temperatures (15h @ 60°C). It is suitable for both tooling and parts manufacturing. Typical applications include large marine structures, wind turbine blades, moulds for pre-preg production. Monolitic carbon fibre infusions may be performed with fibre ratios of over 68% with 0,4% porosity. RESOLTECH RESOLVING YOUR ENGINERING CHALLENGES

MIXING RATIO The mixing ratio must be respected neither excess nor default. The mixture should be homogeneous and intimate with the use. APPLICATION The mixing ratio must be accurately measured. It is not possible to change the ratio, it would result in lower mechanical properties. The mixture should be thoroughly stirred to ensure full homogeneity. Thermosetting products generate heat when curing. The amount of heat generated varies with the hardener used, the temperature and the quantity of resin mixed. It is therefore necessary to only mix the necessary amount usable within the given pot...

CURING & POST CURING The 1800 system, specially when used with the 1805 hardener should not be released from the mould without curing at intermediate temperatures of minimum 12h @ 40º or 6h @ 60º as it remains brittle without this initial cure. It will then require a minimal post curing of 15h to 60°C in order to reach its thermo mechanical properties While a postcure is not mandatory, in order to obtain a material at the maximum of its mechanical properties it is necessary to respect the following recommended cycles: GLASS TRANSITION TEMPERATURES The 60°C temperature cure means that the...
