Master Bond’s high Tg, low-viscosity epoxy meets NASA specifications

By Michelle Froese | September 25, 2019

Master Bond Supreme 112 is a new two part epoxy for bonding, sealing, potting, and impregnation applications. It is a heat-curable system with a very low viscosity of 50 to 200 cps and a long open time of two to three days at room temperature for a 100 gram batch.

Supreme 112 features a high, glass-transition temperature of 190 to 195°C and is serviceable up to 288° C (550° F). This compound bonds well to a variety of substrates including metals, composites, glass, and ceramics. As a toughened glass system, it withstands thermal cycling and mechanical stresses.

“Supreme 112 can be applied successfully not only in bonding applications, but it can also be used in porosity sealing. Additionally, it offers a high tensile strength of 11,000 to 12,000 psi”, says Rohit Ramnath, senior product engineer. “This non-solvent based compound also meets NASA low outgassing requirements.”

Supreme 112 retains its electrical insulation properties even at elevated temperatures. While this system has a relatively easy to use mix ratio, 100:70 by weight, it requires a three step oven curing process of one to two hours at 200° F, followed by three to four hours at 250° F, and then four to six hours at 300° F.

Despite the long cure schedule, Supreme 112 offers a unique combination of performance properties advantageous in many applications in aerospace, electronic, and automotive industries.
