Key Features
- Convenient handling
- Good flow properties
- Black color
- High temperature resistant
Master Bond EP41S-6 is a two part epoxy system that meets UL 1203 for Explosion-Proof and Dust-Ignition-Proof Electrical Equipment for Use in Hazardous (Classified) Locations. The rationale for this test is to prevent explosions and dust ignitions in industrial settings. The 1203 UL designation is specifically for a sealing compound for use in hazardous locations conforming with Class I, Groups A, B, C and D; Class II, Groups E, F, and G Hazardous Locations.
EP41S-6 has a forgiving 100 to 25 mix ratio by weight. The recommended cure schedule is overnight at 75°F followed by 6-8 hours at 150-250°F. Since applications vary, additional post-curing at 250°F for another 5-10 hours is beneficial.
Upon mixing, EP41S-6 is a moderate viscosity liquid with good flow properties. It contains no solvents or diluents and is 100% reactive. It has low shrinkage upon curing. This epoxy combines formidable physical strength properties and electrical insulation values. It bonds well to a wide variety of substrates including metals, composites, glass, ceramics, as well as many rubbers and plastics. EP41S-6 is serviceable over a wide temperature range of -80°F to +500°F.
