Casting Resin


Epoxies, Etc. introduces the 20-2180, a Polyurethane Potting and Encapsulating Resin that has fitting properties for cable and harness assemblies.  The 20-2180 can be poured into a metal or silicone mold to create an assembly with a firm seal around jacketed wires.  Its rubber-like texture makes it ideal for outdoor applications.  It is resilient and won’t crack allowing moisture to creep in.  Use of the 20-2180 resin in small to medium molding applications is more cost effective than the use of injection molds.  The 20-2180 is stable, pours easily, and resists moisture and chemicals.  It self-levels around components and cures quickly with a small amount of heat.  The 20-2180 is also great for other electronic applications, having a low viscosity, low shrinkage, and creating low stress on components.  It has a convenient 2:1 mix ratio, and its base is a natural oil polyol, which is a renewable resource and low in toxicity.  Go green! For even greater ease of use, try the 20-2180 in the TriggerBondâ dual barrel cartridge system – no mixing or measuring required.
