2. Porosity sealing - Wikipedia

   en.wikipedia.org/wiki/Porosity_sealing

   Vacuum impregnation is a preferred OEM process that seals porosity and leak paths in metal castings, sintered metal parts and electrical castings that form during the casting or molding process. Vacuum impregnation stops casting porosity (a phenomenon that occurs in the die-cast manufacturing process and allows manufacturers to use parts that ...

3. Resin casting - Wikipedia

   en.wikipedia.org/wiki/Resin_casting

   Alternately, resin casting may be accomplished with a resin plus a nearly equal amount of a "hardener" liquid (as in many epoxy resin or polyester resin systems), which functionally contains a second polymer, for use in forming a final product plastic which is a copolymer. Copolymers contain two different alternating chemical entities in the ...

4. Resin dispensing - Wikipedia

   en.wikipedia.org/wiki/Resin_dispensing

   A resin dispensing system is a technical installation to process casting resin for the purpose of filling, sealing, covering or soaking technical parts, especially in the field of electricity and electronics like transformers, LCDs and other devices of various size.

5. J-B Weld - Wikipedia

   en.wikipedia.org/wiki/J-B_Weld

   The mixture sets in 4-6 hours and fully cures in up to 15 hours. It can be used as an adhesive, laminate, plug, filler, sealant, or electrical insulator and can be drilled, ground, tapped, machined, sanded, and painted when cured. J-B Kwik is a faster-curing two-part epoxy with medium-temperature resistance up to 300 °F (149 °C).

6. RTV silicone - Wikipedia

   en.wikipedia.org/wiki/RTV_silicone

   RTV silicone rubber can be used to cast materials including wax, gypsum, low-melt alloys/metals, and urethane, epoxy, or polyester resins (without using a release agent). A more recent innovation is the ability to 3D print RTV silicones.

7. Epoxy - Wikipedia

   en.wikipedia.org/wiki/Epoxy

   This process is commonly referred to as curing or gelation process. [27] Curing of epoxy resins is an exothermic reaction and in some cases produces sufficient heat to cause thermal degradation if not controlled. [28] Curing does induce residual stress in epoxy systems which have been studied. [29]
