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. J-B Weld - Wikipedia

   en.wikipedia.org/wiki/J-B_Weld

   The J-B Weld Company is an international company that produces epoxy products. The home office is based in Sulphur Springs, Texas . [ 1 ] J-B Weld (stylized as J-B WELD ) is the name of their flagship product: a specialized, high-temperature epoxy adhesive for use in bonding materials together.

4. 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 ...

5. 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.

6. Epoxy - Wikipedia

   en.wikipedia.org/wiki/Epoxy

   Epoxy is the family of basic components or cured end products of epoxy resins. Epoxy resins, also known as polyepoxides, are a class of reactive prepolymers and polymers which contain epoxide groups. The epoxide functional group is also collectively called epoxy. [1] The IUPAC name for an epoxide group is an oxirane.

7. Bulk moulding compound - Wikipedia

   en.wikipedia.org/wiki/Bulk_moulding_compound

   BMC is manufactured by mixing strands (Greater than 1/8” and less than 2" [2] [3]) of chopped glass fibers, styrene, an initiator, and filler in a mixer with an unsaturated thermoset resin (commonly polyester resin, vinyl ester resin or epoxy resin). The mixing is done at room temperature and stored at low temperatures to slow down curing ...

8. Expanding monomer - Wikipedia

   en.wikipedia.org/wiki/Expanding_monomer

   Expanding monomers are interesting for application as in matrix resins in radically polymerized dental fillings, [5] [6] high-strength composites (e. g. in epoxy resins [7]), adhesives, coatings, precision castings, and sealant materials to counteract shrinking during polymerization. [8]

9. Silicone rubber - Wikipedia

   en.wikipedia.org/wiki/Silicone_rubber

   Once fully cured, condensation systems are effective as sealants and caulks in plumbing and building construction and as molds for casting polyurethane, epoxy and polyester resins, waxes, gypsum, and low-melting-temperature metals such as lead. They are typically very flexible and have a high tear strength.
