Spray forming offers certain advantages over both conventional ingot metallurgy and more specialized techniques such as powder metallurgy.Firstly, it is a flexible process and can be used to manufacture a wide range of materials, some of which are difficult to produce by other methods, e.g. Al-5wt% Li alloys or Al-SiC, Al-Al 2 O 3 metal matrix composites (MMCs).
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 ...
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.
An alkyd is a polyester resin modified by the addition of fatty acids and other components. [1] Alkyds are derived from polyols and organic acids including dicarboxylic acids or carboxylic acid anhydride and triglyceride oils.

PJ1 TrackBite (formerly known as VHT TrackBite or simply VHT) is a custom formulated synthetic resin, typically black in color, used in drag racing to either increase the traction of a car's tires or as a sealer for newly ground and/or resurfaced race tracks. [1] It stays sticky for weeks, has fire-retardant properties, and is hydrophobic. It ...
Resin binders are natural or synthetic high melting point gums. The two common types used are urea formaldehyde (UF) and phenol formaldehyde (PF) resins. PF resins have a higher heat resistance than UF resins and cost less. There are also cold-set resins, which use a catalyst instead of a heat to cure the binder. Resin binders are quite popular ...
This allows for the ultraviolet light to penetrate into the resin, then after the layer has hardened, the build plate can move away pulling the hardened resin away from the FEP film. The plastic is useful as a sample holder material in microscopy applications as its refractive index is close to that of water at visible wavelengths, [ 9 ] [ 10 ...
