3M Scotch-Weld Epoxy Potting Compound DP270 Clear, 48.5mL

Description

From the Manufacturer 3M™ Scotch-Weld™ Epoxy Potting Compound DP270 Clear is a
two-part, low viscosity, self leveling epoxy resin system designed primarily
for potting, sealing, and encapsulation of many electronic components. It is
non-corrosive to copper, non-exothermic and its low viscosity provides high
flow rate, ideal for precise control when dispensing small amounts. It dries
to a clear, amber color with very little shrinkage and its clarity allows
visibility of the component. DP270 also protects the component from moisture
and contaminants and is suitable for outdoor use. This adhesive provides
structural strength and also bonds a wide variety of substrates including
metals, ceramics, wood, and many plastics. This clear drying adhesive and
potting compound begins with low viscosity for easy, controlled dispensing.
The mix ratio is 1:1 and provides a 60 minute work life, which allows plenty
of time to position and to adjust fit prior to setting. The adhesive reaches
handling strength in approximately 3 hours and is fully cured in 48 hours (at
720F/220C). DP270 meets the requirements of UL 94 HB (Horizontal Burn). Both
mixing nozzle and applicator are required for dispensing from the Duo-Pak
cartridge and are sold separately. For best results, always use 3M™ Scotch-
Weld™ EPX™ Plus II Applicator and Mixing Nozzles.Product Information Key

Adhesives? Epoxies are polymeric materials that start out as liquids and
undergo a chemical reaction to form a solid. These compounds are a major part
of the class of adhesives called “structural adhesives,” which includes
polyurethane, acrylic, cyanoacrylate, and others. Epoxies include two
compounds: resins and hardeners. When the two are mixed in their specified
ratio they react chemically; and once the reaction has finished, they form a
strong and rigid plastic material. Once the two parts are mixed, there is a
limited working time in which the epoxy can be applied, ranging from a few
minutes to an hour or longer. These adhesives provide better heat and chemical
resistance than other common adhesives and those that require heat to cure
will be more heat and chemical resistant than those that cure at room
temperature. An epoxy based polymer is mechanically strong, chemically
resistant to degradation, and very tacky during its working time. Epoxy
adhesives are used in the manufacture of buildings, homes, aircraft,
automobiles, bicycles, boats, golf clubs, skis, and snowboards, as well as
many other applications where high-strength bonds are needed along with
resistance to environmental conditions. Epoxy adhesives can be formulated to
meet almost any requirement for bonding wood, metal, glass, stone, and various
plastics. Using different formulations, epoxies can be made flexible or rigid,
transparent or opaque, quick setting or slow setting. Industrial uses for
epoxies range widely and include coatings, adhesives, and composite materials
like carbon fiber and glass-reinforced plastic. They are the preferred choice
for their ability to flow and conform to the work area, strong adhesion,
chemical and heat resistance, and exceptional mechanical and electrical
insulating properties. About 3M Industrial Adhesives and Tapes For more than a
