Mold Max™ 25, member of Smooth-On’s popular Mold Max™ line of high performance tin-cure silicone rubbers. Mold Max™ 25 is mixed 100A:5B by weight and cures overnight to a Shore 25A.
What's Different About Mold Max™ 25?
Compared to the other Mold Max™ products, Mold Max™ 25 has a lower viscosity Part A, making the rubber easier to mix and easier to vacuum de-gas.
The working time for the Mold Max™ 25 is an extra-long 60 minutes for large mold pours or for pouring several molds from a single batch of rubber.
Because it is a Mold Max™ silicone, molds made with the new 25A have high tear strength and a long library life. They are suitable for production casting of urethane, epoxy or polyester resins, wax, gypsum and other materials.
