- Applications
- RECKLI Epoxy WST is used in model- and mold-making, especially when high reactivity and dimensional stability under heat are required.
- For the manufacture of stable backfillings, RECKLI Epoxy WST is mixed with ovendry fillers, such as quartz sand, chalk powder, slag or RECKLI Filler L, yielding an earth-moist ramming mass. To achieve hard, fast-curing compounds, add fine grains or powders of quartz, limestone, slate or wollastonite. The use in the construction-industry is only possible to a limited extent.
- Combined with glass or carbon fibers, RECKLI Epoxy WST yields high-quality laminates or composites for various applications.
- Processing
Add the hardener (B) to the base component (A) and mix them homogenously. Transfer the mixture into a second receptacle and stir it up again. Thereby the incorporation of larger amounts of air should be avoided. Fillers should be preferably added to the mixture rather than to the base component before mixing. Once mixed, the processing of the material must be completed within the pot life (15 _x0013_– _x001e_20 minutes). Mixing larger quantities decreases the processing time.
