FOR IMMEDIATE RELEASE

Toughened Epoxy Polysulfide Hybrid Offers Advanced Chemical Resistance

Master Bond EP21TP-2NV is a two part epoxy polysulfide formulated for use as an adhesive, sealant and potting system. It withstands prolonged exposure to many harsh chemicals including fuels, oils, hydrocarbons and hydraulic fluids. It is also fully RoHS compliant, meeting RoHS3 Directive (EU) 2015/863.

EP21TP-2NV offers an elongation between 40-80% at room temperature and superior toughness with a tensile strength of 3,000-4,000 psi. It resists aggressive thermal cycling over the service temperature range of -80°F to +250°F [-62°C to +121°C]. With a dielectric constant of 3.7 at 60 Hz, the system provides excellent electrical insulation properties.

Master Bond EP21TP-2NV cures at room temperature in 48-72 hours to form a rigid material with a Shore D hardness measuring 60-65. 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 2-3 hours its hardness decreases to 15-20 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.
