Toughened epoxy polysulfide hybrid offers chemical resistance

EP21TP-2NV offers an elongation between 40 to 80% at room temperature and superior toughness with a tensile strength of 3,000 to 4,000 psi. It resists aggressive thermal cycling over the service temperature range of -62 to +121°C. With a dielectric constant of 3.7 at 60Hz, the system provides excellent electrical insulation properties.

Master Bond EP21TP-2NV cures at room temperature in 48 to 72 hours to form a rigid material with a Shore D hardness measuring 60 to 65. A unique feature of EP21TP-2NV is its ability to cure softer with the addition of heat. For example, when cured at 200°F for two to three hours its hardness decreases to 15 to 20 Shore D.

EP21TP-2NV bonds well to a variety of substrates such as metals, glass, ceramics and many rubber and plastic materials. This compound is available in standard size containers from ½ pint, pint, quart and gallon kits as well as specialty packaging including double barrel syringes and gun dispensers.

Master Bond EP21TP-2NV is a two part epoxy polysulfide featuring superior chemical and thermal cycling resistance while maintaining tough, flexible bonds.
