  2. Conservation and restoration of panel paintings - Wikipedia

    en.wikipedia.org/wiki/Conservation_and...

    Panel paintings consist of a wood support, a ground (linen or parchment sized with glues, resin, and gesso), and an image layer (encaustic, tempera, oil). [1] They are typically constructed of two or more panels joined together by crossbeam braces which can separate due to age and material instability caused by fluctuations in relative humidity ...

    en.wikipedia.org/wiki/Resin_casting

    The molds are commonly half-divided (like the hollowed chocolate Easter eggs with candy inside) and a release agent may be used to make removal of the hardened/set resin from the mold easier. The hardened resin casting is removed from the flexible mold and allowed to cool. A Baldwin 6-axle locomotive kit cast in resin in HO Scale

  4. Acrylic resin - Wikipedia

    en.wikipedia.org/wiki/Acrylic_resin

    An acrylic resin is a thermoplastic or thermosetting plastic substance typically derived from acrylic acid, methacrylic acid and acrylate monomers such as butyl acrylate and methacrylate monomers such as methyl methacrylate. Thermoplastic acrylics designate a group of acrylic resins typically containing both a high molecular weight and a high ...

  5. Plastisol - Wikipedia

    While the vinyl part is still warm in the mold, it is very flexible and can be removed from the mold with pliers. When the parts cool, they become rigid and are ready for assembly. The metal molds can produce an unlimited number of castings. Unlike the flexible molds used for resin casting, metal molds are not adversely affected by heat.

    en.wikipedia.org/wiki/Conservation_and...

    Epoxy resin is typically used post-1930s and is an indication of modern conservation work. Generally, epoxy is very hard, but unlike shellac it is not brittle. The color of epoxy resin can range from yellow/green to a dark yellow/brown. Yellowing of the resin is an indication of aging.

  7. Primer (paint) - Wikipedia

    en.wikipedia.org/wiki/Primer_(paint)

    A water-based primer, used primarily on wood. A primer (/ ˈ p r aɪ m ər /) or undercoat is a preparatory coating put on materials before painting.Priming ensures better adhesion of paint to the surface, increases paint durability, and provides additional protection for the material being painted.

  8. Impregnation resin - Wikipedia

    en.wikipedia.org/wiki/Impregnation_resin

    Although wood does have advantages over other building materials, it also has major disadvantages. Wood swells in high humidity and shrinks when the air is dry. [4] It can also decay if allowed to stay moist for extended periods, and has variable properties from board to board. Resin impregnation can improve all these properties.

  9. Resin transfer moulding - Wikipedia

    en.wikipedia.org/wiki/Resin_transfer_moulding

    Usually, the mould is formed from aluminum or steel, but sometimes composite molds are used. The two sides fit together to make a mould cavity. The distinctive feature of resin transfer moulding is that the reinforcement materials are placed into this cavity, and before the introduction of the matrix material, the mould set is closed.
