    00:00:04 masterbond ep41 s-5 is a two-part epoxy system featuring outstanding resistance to many chemicals most noteworthy is its resistance to methylene chloride solvent widely used as a stripping agent for epoxies this system can be utilized for bonding sealing coating and as you'll see in this application encapsulating applying EP 41s -5 with a syringe we are encapsula ating a circuit board using a

    00:00:32 mold to demonstrate tamper proofing the epoxy has a moderate viscosity with good flow we will cure the sample overnight at room temperature followed by a postcure with heat upon cure the epoxy has low shrinkage and features excellent physical strength properties and electrical insulation values it has good adhesion to many types of substrates and is serviceable over a wide temperature

    00:00:56 range of -60° f to plus 3 ° F we tested the chemical resistance of ep41 s-5 by preparing cured castings and immersing them in methylene chloride for 3 months the results show that after 100 days the weight change was less than 5% this demonstrates that the chemical had no effect on the cured epoxy we repeated this test with many other chemicals as well the results confirm

    00:01:26 that this product has excellent resistance to many of the chemicals listed here some with well below a 1% weight change complete test results are provided upon request this system is available in standard packaging as well as a gun dispenser to learn more about ep41 s-5 and how it can be used in your application give us a call
