Urefil 15 /0.32kg

URE-FIL® 15
Micro‑balloons that can be added to Smooth‑On urethane plastics and epoxies to create very light weight castings. Castings which float on water can be created by using proper proportions of URE‑FIL® 15. A casting resin filled with a large proportion of URE‑FIL® 15 can be described as a ‘syntactic foam’, non‑expanding foams which are stiffer, stronger and more water resistant than water‑blown expanding urethane foams of the same density.
