Two component epoxy system featuring excellent chemical resistance especially to solvents, acids, bases, alcohols and fuels
- Convenient handling
- Good flow properties
- Withstands methylene chloride and other aggressive chemicals
- Superior electrical insulation properties
Master Bond EP41S-5 is a two part epoxy system for bonding, sealing and coating with a forgiving 100 to 25 mix ratio by weight. EP41S-5 will cure at room temperature or more rapidly at elevated temperatures. The optimum curing schedule is overnight at 75°F followed by 3-4 hours at 150-200°F. It has exemplary resistance to a wide array of chemicals, especially acids, bases, alcohols, fuels including gasohol, and solvents. Most noteworthy is its resistance to methylene chloride, phenol (10%), nitric acid (30%) as well as ethanol and acetone. Upon mixing, EP41S-5 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-5 is serviceable over a wide temperature range of -80°F to +450°F. The standard color of EP41S-5 is black, additional colors are also available. If required, a non-drip version of this formulation called EP41S-5ND is offered as well. This epoxy system can be used in aerospace, electronic, chemical processing, specialty OEM and in other applications where robust chemical resistance is required (please refer to the chart below).
