Adhesive has exceptional chemical resistance

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.
