Formulated for bonding, sealing, coating and encapsulation applications, Master Bond EP41S-5 is a room temperature curing epoxy that combines a high strength profile, superior electrical insulation values and exceptional chemical resistance. This system can be used in the aerospace, electronic, power, chemical processing, specialty OEM and other industries.
Well suited for coating pumps, tanks, storage vessels and piping, EP41S-5 is able to deliver long-term protection against a wide array of chemicals including acids, bases, alcohols, fuels and many solvents. Most noteworthy is its resistance to methylene chloride, a common stripping agent. This makes EP41S-5 ideal for tamper proofing applications in the electronic industry.
EP41S-5 offers convenient handling with a 100 to 25 mix ratio by weight. The mixed epoxy has good flow properties with a moderate viscosity of 25,000-30,000 cps. It bonds well to a wide variety of substrates including metals, composites, glass, ceramics, as well as many rubbers and plastics. EP41S-5 will cure at room temperature or more rapidly at elevated temperatures. Upon curing, this system is rigid, with a hardness of 85-95 Shore D. It has a tensile strength of 10,000-12,000 psi at room temperature. Additionally, EP41S-5 features reliable electrical insulation characteristics with a dielectric constant of 3.5 at 60 Hz and a volume resistivity greater than 1014 ohm-cm.
EP41S-5 is serviceable over the wide temperature range of -80°F to +300°F [-62°C to +149°C]. Its natural color is black, but can be formulated in additional colors. This solvent free system is available for use in ½ pint, pint, quart, gallon and 5 gallon container kits as well as double barrel cartridges that can be dispensed in gun applicators.
