Unsaturated polyester which was mixed with the methyl ethyl ketone peroxide (MEKP) as catalyst 100: 2 were stirred until its changes its physical colour from light pink to pale yellow.
Different parameters were varied: the MEKP concentration, reinforcement layer thickness, acrylic material was heated or not, reinforcement layer was with or without the glass fibres, etc.
NetDimensions said mEKP is the end-user version of its Enterprise Knowledge Platform (EKP) learning and performance management system.
Polyurethane (Helmsman spar urethane), purchased from Lowe's, and wax (Mainstays candle), purchased from Wal-Mart, and UPE resin (formulation: 100 parts of UPE, 15 parts of styrene, 0.5 part of CoNa, and 1.0 part of MEKP) were used as edge-sealing agents.
The catalyst and accelerator used here was Methyl Ethyl Ketone Peroxide (MEKP) and Benzyl Peroxide respectively.
Ken-React CP-03 for MEKP unsaturated polyester bubble-free gel coats.
The selected resin shows clear color with a solid content of 63.5%, because the curing process of methyl ethyl ketone peroxide (MEKP) was employed.
Other literature available from the company describes the use of Ken-React NZ 66A (mercapto zirconate) in sulfur-cured elastomers; injection molding; a new coupling agent for MEKP cast polyester; permanent antistats; PVC; foamed polymers; fiber reinforced thermosets; and a new Kenflex A aromatic plasticizer.
Demand for organic peroxides such as benzoyl peroxide, methyl ethyl ketone peroxide (MEKP) and a number of others will benefit from expected growth in plastics production and the development of improved products, moderated by competition from other polymerization initiators.
In casting, the moulds were first sprayed with silicone release agent and then catalysed (MEKP catalyst) and coloured polyester gelcoat resin was painted onto the mould.
* dilution - unstable methyl ethyl ketone peroxide (MEKP) is widely employed as a hardener in fibreglass resins when diluted in a compatible solvent.
