(processing with Hardener W 300)
100 : 35 parts by weight of resin to hardener
Pot life (135 g / 20 °C (68 °F)): approx. 300 minutes
Curing time: approx. 24–72 h (depending on volume, layer thickness and temperature)
Aquaristics, terraristics, arts and crafts, wood finishing, furniture construction (Rivertable), slides, aircraft, ship, car, and railway model construction.
For optimum results, resin and hardener should be dosed by weight.
(Mixing ratio by weight is not equal to mixing ratio by volume due to different specific weights of resin and hardener.)
After mixing the resin and hardener, the casting resin must be poured into the mould as quickly as possible to avoid an
exothermic reaction in the mixing vessel. This is especially true when larger quantities are processed.
The reaction heat (exothermic) generated during hardening limits the maximum quantity to be poured in one operation and the
The higher the temperature and/or layer thickness and/or volume, the shorter the processing/gelling time.
If a certain limit is exceeded, the resin system heats up exponentially until undesired reactions finally occur:
The casting discolours completely or in places, from light yellow to dark brown, cracks appear and increased shrinkage occurs.
Furthermore, a restless, wavy surface is formed. In extreme cases, the casting can "boil" completely or partially. Temperatures
above 100 °C then occur.
Layer thicknesses up to 5 cm for small volumes up to approx. 500 ml and layers from 1-2 cm for large volumes up to
approx. 30 liters can be cast.
Large moulded parts ("river tables" etc.) with layer thicknesses of more than 20 mm should be cast in two or more work steps/
layers one after the other at intervals of about 12 hours.
At temperatures above 25 °C (77 °F), we strongly advise against casting larger layer thicknesses and/or larger volumes
in one operation.
Please order Hardener W 300 separately.
