About the product

SR CA85 + SD 8703 (Casting / Industrial up to 12cm) by Sicomin is an ultra deep epoxy resin for deep pour work, with a maximum working layer of 12 cm. The database records a 100:17.5 mix ratio, working time around 2 h (120 min), transparency described as filled / opaque casting resin, UV resistance: low to medium and viscosity: very high / filled casting system (~6220 mPas @20C, 2050 mPas @30C). Full cure is listed as 7 days (168 h), so mechanical work should be planned with a safety margin rather than only around demolding time.

Working with it

For SR CA85 + SD 8703 (Casting / Industrial up to 12cm), the key is calm setup and process control. Work at a stable temperature around 15-25C; in colder conditions this resin may cure more slowly, turn cloudy or remain soft on the surface. Keep the 100:17.5 ratio and mix slowly but thoroughly; with this resin class, poor mixing causes problems more often than the product itself. Nie jest primerem do drewna; raczej system do zalewania technicznego i calage. The 12 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 CA85 + SD 8703 (Casting / Industrial up to 12cm) is best treated as a product for projects where the layer limit, patient degassing and full cure time of 7 days (168 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.
