How to Use 3M Scotchcast Electrical Insulating Resin 4

Scotchcast Electrical Insulating Resin 4 is a two-part epoxy insulating and encapsulating resin. Its compatibility with solid and synthetic cable insulations jackets makes Resin 4 an excellent insulator and sealer for cable splicing. We will discuss how to make a watertight submersible splice that is well insulated and provides superior resistance to the environment. A little background on why we offer this type of splice: we needed a solution to situations where traditional splices were not holding up due to water permeation, corrosion, and or condensation. This solutions provides the highest level of impermeable encapsulation of the wire connection to offer a high degree of protection. If you find yourself in a situation where you need a to make a watertight splice and have no splice box or need to make the splice outside of the splice box, this is a splice that will allow for those situations. What we have for this video is: Rubber Gloves Safety Glasses Scotchcast Insulating Resin /UL Listed Panduit Wire Joints (2 sizes) / UL Listed PVC Resin Vile (2 sizes) Wire Strippers Razor Knife Crimping Pliers Before I begin, I want to mention that this method is most commonly applied to repairs as opposed to new installations where the option to use proper splice boxes and conduit seal off is possible. Without getting into the details of legality and so forth on permitted jobs, check with your local inspector before using this method to ensure approval. So let’s look at our resin for just a moment before we get started (open package). Here is what this resin looks like, it's a 2 part resin that begins to cure once the two mixtures are combined. We offer these in two sizes, A & B. A is the smaller size and B is the larger size. We will talk about what these different sizes mean a little later in the video. Now the fun part: We will be splicing UF Cable to our float switch cable. This will simulate replacing a float switch in a septic tank. The first step is to get your wires prepared. Using the resin vile determine how much of the cable jacket to remove. The jacket needs to be included in the resin for an optimal seal. Strip and trim your wires to have a ½” offset leaving the wire joints staggered. This is so that they have ample room inside the vial. Before preparing the resin, dry fit your wires to ensure the jacket will be covered with the resin and that the connections fit. An additional options step is to fill the vial with water and place the wire and joints into the vial to determine the proper fill depth of the resin. Be sure if you do this to completely dry the wire and vial afterwards. Using your crimping tool, crimp the wire joints securely in place. Now it’s time for your safety glasses and gloves, Mix and pour the resin into the vial to the appropriate fill level. Slowly insert the wires and just as the wire joint is submerged bob slightly up and down to work the air out since this resin is so viscous that air bubbles will not escape easily otherwise. One the joints are filled push the wire the rest of the way down keeping it centered to avoid scraping against the walls of the tube as you initially insert the wire. Since this resin takes hours to completely cure you will want to use some method to secure the vial in the vertical position. Two possible methods would be using the riser pipe or to secure the vial to the extra loops of wire inside the basin or tank. We will quickly show both. Now after this resin has completely cured this splice solution will generally provide the most resistance to corrosion and condensation compared to other products on the market. So quickly we will jump back to the A & B sizes and the sizing of these resin vials. The A being the smaller of the two will generally fill two ¾” vials or one 1” vial. The B size is used for up to 4 smaller vials or two larger vials. It's better to have a little extra than not enough. The vials are intended for single splices thought the large vials can be used for multiple if needed. Have a question?
