Rehabilitation

It was therefore necessary to eschew traditional materials and import synthetic resins which make light, robust prostheses. The problem with these resins is that they do not keep well in tropical conditions and a regular supply must be kept up to ensure continuity in production.
Other Applications of Glycerine
Published in Eric Jungermann, Norman O.V. Sonntag, Glycerine, 2018
Aliphatic solvents may be used when the alkyd ratio is reduced to about 40. Resins of this type may be applied by roller coating or spraying. Applications are in air-drying pigmented enamels, metal coating, auto and truck refinishing, general maintenance paints, and outdoor sign painting. Where the alkyl ratio is about 30, the viscosity is still lower and enamels made with these resins can be brushed. The main uses are architectural finishes, such as trim and trellis paints and where coatings of high flexibility are needed. A good example is in tubes used for holding flexible materials. During World War II, many marine finishes were formulated with this type of resin. Glyceryl phthalate resins frequently are formulated with other types of synthetic resins and film-forming materials. Alkyds are also used to improve the flexibility, adhesion, toughness, and other properties of urea-formaldyhyde resins and melamine formaldehyde resins. Color, mar resistance, hardness, and baking cycles are among the characteristics improved by such combinations. Paint technologists agree that no other film-forming materials complement the qualities of amino resins as do the alkyds.

Thermosetting materials are curable plastics consisting of phenols (cresol or resorcinol), formaldehydes, urea, and melamines. Synthetic resins are materials used in the production of plastics (in an unshaped state as powders or liquids) and their precursors. During fabrication, chemical reactions take place under the influence of initiators (curing agents) or by application of heat, and these reactions produce huge spatially cross-linked molecules through interlinking (Figure 5.6).

Each cadaveric specimen was subjected to bilateral channeling of the proximal segments of the vertebral arteries; through these vessels, it was performed a lavage and pre-setting of the brain with formaldehyde 3%. Thereafter, the vertebral arteries were injected with 100cc of semi-synthetic resin (a mixture of Palatal E210® BASF 80 cc and Styrene 20 cc) dyed with mineral red. After 30 minutes, once obtained the resin polymerization, the exeresis of the encephalon was performed. Then, the anatomical pieces were subjected to a formaldehyde 10% fixation for 15 days.

According to the previous report (Aboud & Griffin, 2014), silver staining was performed as follows: after being deparaffinized and hydrated, paraffin sections were treated with 20% silver nitrate in 60 °C for 15 min. With the double washing with distilled water, sections were subsequently incubated with ammoniacal silver solution (15 min) and sodium thiosulfate solution (2 min). The sections then were dehydrated and mounted with synthetic resin. The structure of NFTs in brain section was observed under a confocal microscope.

Styrene monomer (SM) is a basic chemical used as a raw material for polystyrene and unsaturated polyester resins as well as in the production of synthetic resins, synthetic rubbers, paints, and adhesives [3]. Polystyrene resins are found in plastic products in household appliances (e.g. color televisions), office equipment (e.g. personal computers and printers), and other goods (e.g. toys). Unsaturated polyester resins are used for resin tanks, bathtubs, and floor linings.
