Resin casting is a method of plastic casting where a mold is filled with a liquid synthetic resin, which then hardens. It is primarily used for small-scale production like industrial prototypes and dentistry. It can be done by amateur hobbyists with little initial investment, and is used in the production of collectible toys, models and figures ...
Bisphenol A diglycidyl ether (commonly abbreviated BADGE or DGEBA) is an organic compound and is a liquid epoxy resin. [1][2][3][4][5] The compound is a colorless viscous liquid (commercial samples can appear pale straw-coloured). [6][7] It is a key component of many epoxy resin formulations. Addition of further Bisphenol A and a catalyst and ...
Fusion bonded epoxy coating, also known as fusion-bond epoxy powder coating and commonly referred to as FBE coating, is an epoxy -based powder coating that is widely used to protect steel pipe used in pipeline construction from corrosion. It is also commonly used to protect reinforcing bars (though being phased out as of 2005 [1]) and on a wide ...
A black carbon fibre (used as a reinforcement component) compared to a human hair. Composites are formed by combining materials together to form an overall structure with properties that differ from that of the individual components. A composite material (also called a composition material or shortened to composite, which is the common name) is ...
Epoxy. A syringe of "5-minute" epoxy glue, containing separate compartments for the epoxy resin and the hardener. Structure of the epoxide group, a reactive functional group present in all epoxy resins. Epoxy is the family of basic components or cured end products of epoxy resins.
Synthetic casting "resin" for embedding display objects in Plexiglas/Lucite (PMMA) is simply methyl methacrylate liquid, into which a polymerization catalyst is added and mixed, causing it to "set" (polymerize). The polymerization creates a block of PMMA plastic ("acrylic glass") which holds the display object inside a transparent block.
Phenol formaldehyde resins (PF) (phenolic resins or phenoplasts [1]) are synthetic polymers obtained by the reaction of phenol or substituted phenol with formaldehyde. Used as the basis for Bakelite, PFs were the first commercial synthetic resins. They have been widely used for the production of molded products including billiard balls ...
The epoxy value is defined as the number of moles of epoxy group per 100g resin. So as an example using an epoxy resin with molar mass of 382 and that has 2 moles of epoxy groups per mole of resin, the EEW = 382/2 = 191, and the epoxy value is calculated as follows: 100/191 = 0.53 (i.e. the epoxy value of the resin is 0.53).
