Methyl ethyl ketone peroxide (MEKP) is an organic peroxide with the formula [(CH 3)(C 2 H 5)C(O 2 H)] 2 O 2. MEKP is a colorless oily liquid. It is widely used in vulcanization (crosslinking) of polymers. [3] It is derived from the reaction of methyl ethyl ketone and hydrogen peroxide under acidic conditions.
Renewable precursors to vinyl ester resins have been developed. [2] Vinyl resins are often used in repair materials and laminating because they are waterproof and reliable. Bisphenol A is a precursor in production of major classes of resins, including the vinyl ester resins along with epoxy resins and polycarbonate. This application usually ...
Since vinyl ester resins must be pre-accelerated with amine accelerator or cobalt, their processing time at room temperature is shorter than with epoxy-based prepregs. Catalysts (also called hardeners) include peroxides such as methyl ethyl ketone peroxide (MEKP), acetyl acetone peroxide (AAP) or cyclohexanone peroxide (CHP).
Thus, organic peroxides are useful as initiators for some types of polymerization, such as the acrylic, unsaturated polyester, and vinyl ester resins used in glass-reinforced plastics. MEKP and benzoyl peroxide are commonly used for this purpose. However, the same property also means that organic peroxides can explosively combust.
Vinyl ester resin is an example of a synthetic resin. [1] Synthetic resins are industrially produced resins, typically viscous substances that convert into rigid polymers by the process of curing. In order to undergo curing, resins typically contain reactive end groups, [2] such as acrylates or epoxides. Some synthetic resins have properties ...
In addition to applications as ceramic matrix composite precursors, silicone resins in the form of polysiloxane polymers made from silicone resins with pendant acrylate, vinyl ether or epoxy functionality find application as UV, electron beam and thermoset polymer matrix composites where they are characterised by their resistance to oxidation ...
Polyvinyl butyral (or PVB) is a resin mostly used for applications that require strong binding, optical clarity, adhesion to many surfaces, toughness and flexibility. It is prepared from polyvinyl alcohol by reaction with butyraldehyde. The major application is laminated safety glass for automobile windshields. [1]
