2. 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 ...

3. Epoxy - Wikipedia

   en.wikipedia.org/wiki/Epoxy

   Epoxy resin formulations are important in the electronics industry, and are employed in motors, generators, transformers, switchgear, bushings, insulators, printed wiring boards (PWB), and semiconductor encapsulants. Epoxy resins are excellent electrical insulators and protect electrical components from short circuiting, dust and moisture.

4. Potting (electronics) - Wikipedia

   en.wikipedia.org/wiki/Potting_(electronics)

   When epoxy resins are used, low chloride grades are usually specified. [1] Many sites recommend using a potting product to protect sensitive electronic components from impact, vibration, and loose wires. [2] In the potting process, an electronic assembly is placed inside a mold (the "pot" [3]) which is then filled with an insulating liquid ...

5. Sheet moulding compound - Wikipedia

   en.wikipedia.org/wiki/Sheet_moulding_compound

   Alternatively the resin and related materials may be mixed on site when a producer wants greater control over the chemistry and filler. SMC is both a process and reinforced composite material. This is manufactured by dispersing long strands (usually >1”) of chopped fiber, commonly glass fibers or carbon fibers on a bath of thermoset resin ...

6. Bulk moulding compound - Wikipedia

   en.wikipedia.org/wiki/Bulk_moulding_compound

   The mixing is done at room temperature and stored at low temperatures to slow down curing prior to molding. The concentration of the mixture can vary depending on application, but is typically 30% glass fibers, 25% filler, and 45% resin, styrene, and initiator. [2] The material is provided in bulk or in logs approximately 4" in diameter.

7. Vacuum assisted resin transfer molding - Wikipedia

   en.wikipedia.org/wiki/Vacuum_assisted_resin...

   Vacuum Assisted Resin Transfer Molding (VARTM) or Vacuum Injected Molding (VIM) is a closed mold, out of autoclave (OOA) [1] composite manufacturing process. VARTM is a variation of Resin Transfer Molding (RTM) with its distinguishing characteristic being the replacement of the top portion of a mold tool with a vacuum bag and the use of a vacuum to assist in resin flow.
