Alumilite Clear SLOW Casting Resin

Alumilite Clear Slow Casting Resin is the go-to urethane resin for woodturners and casters who need extended working time, exceptional clarity, and reliable results in larger or more complex castings. With a 12-minute open time and reduced heat buildup, Clear Slow allows for controlled pours, improved bubble release, and superior results in pen blanks and turning stock.

This high-impact, optically clear resin can be easily dyed or pigmented and turns, sands, and polishes to a mirror-like gloss. Pressure casting is strongly recommended to achieve 100% bubble-free castings. Compared to faster-setting clear resins, Clear Slow offers improved clarity retention and greater forgiveness during mixing and pouring.
