MAINTENANCE
The resin and hardener should be bonded at a temperature of at least +20°C. Gelling time is about 1,5 hours, and the time of full curing is 24 hours.
Forbids to mix a large amount of resin with a hardener immediately, without using special mixing machines to avoid an effervescence.
When fiberglass-made products manufacturing, it is recommended to make a test sample for each batch of resin and hardener.
Heating considerably accelerates the curing process. As self-curing occurs with the calorification, when preparing large dose of resin with a hardener, self-heating of the mixture is possible, accompanied by foaming and rapid solidification.
TRAITS
Epoxy resins are thermoplastic, but under the influence of various hardeners they are converted into non-meltable polymers. The resins curing process can occur at normal room temperature +20°C.
There are two ways to the resin temporarily viscosity decreasing: one is the heating of the mixture, and the second is the addition of a solvent.The resin with low viscosity is easier to apply with a brush or roller, it quickly impregnates fiberglass and penetrates deeper into porous surfaces like rot damaged wood.
The hardener is added at a rate of 10% by weight of the resin.
The non-cured diane epoxy resin ED-20 can be converted into a non-meltable and insoluble condition by the action of various type curing agents – aliphatic and aromatic di- and polyamines, low-molecular polyamides, di- and polycarboxylic acids and their anhydrides, phenol-formaldehyde resins and other compounds.Depending on the hardener used, the properties of the cured epoxy resin ED-20 can vary within the widest range.The most commonly used hardener is PEPA (polyethylenepolyamine).
SAFETY INFORMATION
People who working with epoxy resin ED-20 must be provided with workwear and individual security measures. All activities while working with epoxy resins must be realized in the premises, equipped with flowing-exhaust ventilation.
GUARANTEED SHELF LIFE 18 months
Epoxy-diane resin ED-20 is stored in tightly closed tare in closed warehouses at temperature nothigher than +40⁰С.
