EP Casting Resin WATER-CLEAR + Hardener W300, 1350g working pack

• Highly transparent, almost water-clear components
• Good UV resistance
• Largely bubble-free
• Polishable, hard surface
• Very good impact strength
• Low shrinkage
• Can be coloured with R&G universal colour pastes or transparent colours and dry pigments of all kinds
• Can be modified with all dry fillers (metal powder, effect pigments, sand, etc.)
• Also suitable for coatings and as a laminating resin system with a very long pot life

Mixing ratio:
100 : 35 parts by weight resin : hardener
100 : 42 parts by volume resin : hardener

Processing time (135 g / 20 °C): approx. 300 minutes
Curing time: approx. 24–72 hours (depending on volume, layer thickness and temperature)

Areas of application:
Aquaristics, terraristics, handicrafts, wood finishing, furniture construction (river table), dioramas, model making (aircraft, ships, cars and railways).

Processing:
For optimal results, resin and hardener should be dosed by weight.
(The mixing ratio by weight is not identical to the mixing ratio by volume, due to the different specific gravities of resin and hardener).

After mixing the resin and hardener, the casting resin must be poured as quickly as possible to avoid an exothermic reaction in the mixing vessel. This applies in particular when large quantities are processed.

The heat of reaction (exotherm) generated during curing limits the maximum quantity to be poured in one operation and the layer thickness.
The higher the temperature and/or the layer thickness and/or the volume, the shorter the processing/gelation time.
If a certain limit is exceeded, the resin system heats up exponentially until unwanted reactions occur: the casting discolours completely or partially, from light yellow to dark brown, cracks appear and increased shrinkage occurs. Furthermore, an uneven, wavy surface forms. In extreme cases, the casting can "boil" completely or partially. Temperatures of over 100 °C can then occur.

Layer thicknesses of up to 5 cm for small volumes up to approx. 500 ml, and layers of 1-2 cm for large volumes up to approx. 30 litres can be cast.

At temperatures above 25 °C, we strongly advise against pouring thicker layers and/or larger volumes in one operation.
