About the product

SR 8500 + SZ 8525 (Fast & clear hot-process epoxy) by Sicomin is a casting epoxy resin for river table work, with a maximum working layer of 0.5 cm. The database records a 100:25 mix ratio, working time around 1.4 h (85 min), transparency described as clear to light yellow after mix; clear after cure, UV resistance: medium and viscosity: no viscosity data. Full cure is listed as 5 days (120 h), so mechanical work should be planned with a safety margin rather than only around demolding time.

Working with it

For SR 8500 + SZ 8525 (Fast & clear hot-process epoxy), the key is calm setup and process control. Work at a stable temperature around 23-30C; in colder conditions this resin may cure more slowly, turn cloudy or remain soft on the surface. Keep the 100:25 ratio and mix slowly but thoroughly; with this resin class, poor mixing causes problems more often than the product itself. For wood and porous substrates, apply a seal coat before the main pour. The 0.5 cm layer limit should not be treated as extra safety margin when the mass is high, the mold is closed or the workshop is warm. Use the two-cup method: after the first mix, transfer into a second cup and mix again to reduce streaks and soft spots from the cup walls.

Summary

SR 8500 + SZ 8525 (Fast & clear hot-process epoxy) is best treated as a product for projects where the layer limit, patient degassing and full cure time of 5 days (120 h) matter. Choose a finish according to exposure, abrasion and expected sheen. Before the final pour, make a small sample using the target wood, pigment and workshop temperature.

Product FAQ

What is the maximum layer for Sicomin SR 8500 + SZ 8525 (Fast & clear hot-process epoxy)?

The NeuroResin database lists the maximum working layer as 0.5 cm. For larger masses, warmer workshops or closed molds, keep a safety margin.

What is the working time of Sicomin SR 8500 + SZ 8525 (Fast & clear hot-process epoxy)?

The listed working time is about 1.4 h (85 min). It depends on temperature, mixed mass and pour geometry.

When does Sicomin SR 8500 + SZ 8525 (Fast & clear hot-process epoxy) reach full cure?

Full cure is listed as 5 days (120 h). Demolding may be possible earlier, around 1 day (24 h), but machining is best planned after full cure.
