Polyester resins are synthetic resins formed by the reaction of dibasic organic acids and polyhydric alcohols. Maleic anhydride is a commonly used raw material with diacid functionality in unsaturated polyester resins. [1] Unsaturated polyester resins are used in sheet moulding compound, bulk moulding compound and the toner of laser printers.
One example is in model building, where a grassy texture may be applied to a surface to make it look more realistic. Similarly, it is used by model car builders to get a scale carpet effect. Another use is on a Christmas tree , which may be flocked with a fluffy white spray to simulate snow .

Alkyd resins are usually classed as long oil, [11] medium oil and short oil. [12] These terms represent the oil length in the resin. [13] Alkyds are also modified with phenolic resin, styrene, vinyl toluene, acrylic monomers (to make them dry more quickly) and isocyanates to produce a polyurethane modified alkyd.
Most coatings have four basic components. These are the resin, solvent, pigment and additive systems [5] but the resin or binder is the key ingredient. Continuing environmental legislation in many countries along with geopolitics such as oil production are ensuring that chemists are increasingly turning to waterborne technology for paint/coatings and since resins or binders are the most ...
The term is used more generally to refer to the visual arts (such as painting, sculpture, ceramics, architecture, film and photography), rather than literature and music. [ 1 ] [ 2 ] Materials for use in the plastic arts, in the narrower definition, include those that can be carved or shaped, such as stone or wood , concrete , glass , or metal .

Polyester is favored for strip lining as it is thin, durable, and load-bearing. [2] When paired with a flexible adhesive such as BEVA 371, polyester strip linings cause less deformation of the painting plane. [2] Polyester sailcloth is favored specifically because it is stiff, resists degradation, and can withstand a greater tensile load than ...
