The EP41S-F from Master Bond (Hackensack, NJ) is a two part epoxy for bonding, sealing, coating and encapsulation applications. It combines fast ambient temperature cure speed with chemical resistance and superior electrical insulation properties. This versatile system is easy to handle and has a forgiving 100 to 25 mix ratio by weight. After mixing, EP41S-F polymerizes quickly and can usually be removed from a fixture within 20-30 minutes. Full cures are achieved in 24 hours at 75°F or in 45-60 minutes at 200°F. Other benefits include:
- High strength values with a tensile lap shear strength of over 2,500 psi and a tensile strength of 8,000-9,000 psi.
- The ability to bond well to a wide variety of substrates including metals, composites, ceramics, glass and many plastics, with minimal shrinkage upon curing.
- Easy application, by brushing, dipping or gun dispenser.
- A Shore D hardness exceeding 75. It is 100% reactive and does not contain any solvents or diluents.
EP41S-F is serviceable over the temperature range of -60°F to +250°F. Though it is available in a variety of colors, its standard colors are clear for Part A and amber for Part B. This epoxy can be used in aerospace, electronic or chemical processing applications. It can be recommended for lining of tanks and other chemical equipment.
