Epoxy Potting Compound

The 3M™ Scotch-Weld™ DP270 epoxy encapsulating compound is of low viscosity to facilitate dispensing and encapsulating. It is not corrosive to copper, has minimal exothermic properties, and very low shrinkage, making it suitable for encapsulating and bonding electronic and electrical components.

If you need to use a Duo-Pak (DP) adhesive, trust the 3M dispensing equipment for convenient and precise dosing, mixing, and dispersion.

Epoxy compound with a 70-minute working life
Our 3M™ Scotch-Weld™ DP270 encapsulating epoxy compound is a two-part rigid epoxy system with a 1:1 mixing ratio and a 70-minute working life. It provides initial strength in approximately 3 hours with a 2,500 PSI at 22°C (72°F). Additionally, our 3M™ Scotch-Weld™ DP270 encapsulating epoxy compound is of low viscosity for easy dispensing and encapsulating, and it is non-corrosive to copper. It offers good resistance to medical sterilization and is available in opaque black amber and clear colors.

What are epoxy adhesives?
Epoxy adhesives are part of the class of adhesives called “structural adhesives,” which include polyurethane, acrylic, cyanoacrylate, and others. These adhesives are formulated as reactive liquid polymers that undergo a chemical reaction when mixed and then cure to form a solid plastic material. Once the two parts are mixed in their specified ratio, the curing process begins. They offer a limited working time during which the adhesive can be applied, and the two surfaces can be positioned as needed. This working life can range from a few minutes to several hours. These structural adhesives provide high shear and peel strengths, depending on the formula, and better resistance to heat and chemicals than other common adhesives. In general, epoxy adhesives have the highest overall strength and offer the best performance and resistance to high temperatures, solvents, and weather conditions.

Epoxy adhesive (often referred to as epoxy glue) is widely used in building and housing construction, aircraft and automobile manufacturing, assembly of bicycles, boats, golf clubs, skis, and snowboards, as well as in a variety of household and other applications. It is used practically anywhere high-strength joints are needed, along with resistance to weather conditions. These adhesives are popular for their ease of use, mechanical strength, and chemical resistance. Formulations can be created to make this type of adhesive for flexible plastic or rigid metal, clear or opaque epoxy resin, and fast or slow curing. The versatility in which these adhesives can be formulated helps meet almost any requirement for bonding wood, metal, glass, stone, and various plastics.
