Product Description
Mold Max™ 60
Mold Max™ 60 is a Shore 60A tin catalyzed silicone mold rubber formulated for applications requiring high heat resistance (up to 560°F/294°C). It features a low mixed viscosity and cured rubber exhibits very low linear shrinkage. Parts A & B are mixed 100A & 3B by weight. Pot life is 40 minutes and cure time is 24 hours. Applications include making foundry patterns, flat pattern reproductions and casting low-melt metal alloys such as tin and pewter.
MT-13™
Smooth-On MT-13™ is a premium performance epoxy for applications requiring maximum holding power and water resistance. MT-13™ is a two component epoxy adhesive cement which is mixed in equal parts by volume (100A/123B by weight) Pot Life is 35 minutes and handling strength develops in 16 hours at 73° F / 23° C. MT-13™ adheres extremely well to both porous and non-porous surfaces. MT-13™ is widely used by the boating industry for assembly and general repair. MT-13™ also maintains holding power under extreme cold conditions.
