  2. J-B Weld - Wikipedia

    en.wikipedia.org/wiki/J-B_Weld

    J-B Weld is a two-part epoxy adhesive (or filler) that can withstand high-temperature environments. J-B Weld can be used to bond surfaces made from metal, porcelain, ceramic, glass, marble, PVC, ABS, concrete, fiberglass, wood, fabric, or paper. [7] [8] Alcohol should be avoided when cleaning surfaces, as it can degrade the bond. [9]

  3. Fusion bonded epoxy coating - Wikipedia

    en.wikipedia.org/wiki/Fusion_bonded_epoxy_coating

    The resin and hardener part together is known as the "Binder". As the name indicates, in Fusion bonded epoxy coatings the resin part is an "epoxy" type resin. “Epoxy” or “Oxirane” structure contains a three membered cyclic ring — one oxygen atom connected to two carbon atoms – in the resin molecule. This part is the most reactive ...

  4. Fiberglass - Wikipedia

    en.wikipedia.org/wiki/Fiberglass

    Resin—typically a 2-part thermoset polyester, vinyl, or epoxy—is mixed with its hardener and applied to the surface. Sheets of fiberglass matting are laid into the mold, then more resin mixture is added using a brush or roller. The material must conform to the mold, and air must not be trapped between the fiberglass and the mold.

  5. Fiberglass spray lay-up process - Wikipedia

    en.wikipedia.org/wiki/Fiberglass_spray_lay-up...

    The difference comes from the application of the fibre and resin material to the mould. Spray-up is an open-moulding composites fabrication process where resin and reinforcements are sprayed onto a reusable mould. The resin and glass may be applied separately or simultaneously "chopped" in a combined stream from a chopper gun.

  6. FR-4 - Wikipedia

    en.wikipedia.org/wiki/FR-4

    FR-4 is a composite material composed of woven fiberglass cloth with an epoxy resin binder that is flame resistant (self-extinguishing). "FR" stands for "flame retardant", and does not denote that the material complies with the standard UL94V-0 unless testing is performed to UL 94, Vertical Flame testing in Section 8 at a compliant lab.

  7. Polymer matrix composite - Wikipedia

    en.wikipedia.org/wiki/Polymer_matrix_composite

    Thermoset resins require addition of a curing agent or hardener and impregnation onto a reinforcing material, followed by a curing step to produce a cured or finished part. Once cured, the part cannot be changed or reformed, except for finishing.

  8. 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 ...

  9. Epoxy - Wikipedia

    en.wikipedia.org/wiki/Epoxy

    When using latent hardeners, the epoxy resin and hardener may be mixed and stored for some time prior to use, which is advantageous for many industrial processes. Very latent hardeners enable one-component (1K) products to be produced, whereby the resin and hardener are supplied pre-mixed to the end user and only require heat to initiate curing.
