Accelerator NL-51PN is a solution of 6% cobalt in solvent mixture used for curing UP resins at ambient temperatures. Please check with Resin manufacturer if the Gelcoat/resin is pre-accelerated or not before adding the Accelerator. The cobalt bis(2-ethylhexanoate)/cobalt octoate accelerator is used to activate these organic peroxides (generally ketonperoxides) in the hardening of unsaturated polyester resins. Functions. Engineered Stone, Gelcoats, Buttons, Continuous Laminating, Resin Transfer Molding, Filament winding, Vinylesters, Cold curing polyester and vinylester resins: - Laminating resins - Gelcoats - Sealants - … Figure 1: Overview of available cobalt-free accelerators. The styrene serves two purposes: firstly it acts as a solvent for the resin and secondly it enables the resin to be cured from a liquid to a solid by cross-linking with the polyester chain, without the evolution of … Engineered Stone, Gelcoats, Buttons, Continuous Laminating, Resin Transfer Molding, Filament winding, https://www.resin-supplies-shop.com/Cobalt-accelerator-6-solution-250ml Adding extra Cobalt to pre accelerated systems can result in very quick gel cure times. Abstract. Accelerator Applications. Most Polyester Resins are now available pre-accelerated but some still require separate accelerator addition. Appliance. ... (MEKP) as catalyst, cobalt octoate (C oct) as an accelerator, calcium carbonate (CaCO 3) as filler and glass fibers as reinforcements are used as process variables. Curing of UP resin is a key for successful FRP processing. Functions. Proper selection of cobalt-free accelerator and organic peroxide can have a positive impact on the residual styrene level. Unsaturated polyester (UP) resin is a principle binder material used in FRP products. UNSATURATED POLYESTER RESINS The cure of unsaturated polyesters is achieved by the use of a metallic accelerator, typically cobalt, and a peroxide or hydroperoxide initiator to effect the oxidative cross linking of the unsaturation in the polyester resin. On organic peroxides the accelerator has the function of increasing the speed of formation of the radicals so as to allow the polymerization reaction. Cobalt, Cobalt Octoate with Resin, Cobalt Accelerator manufacturer / supplier in China, offering Metal Content 12% Cobalt Octoate Accelrator for Unsaturated Polyester Resin, 1200tex E-Glass Fiberglass Direct Roving for Making Rebar, 1200tex Fiberglass Direct Roving for Pultrusion and so on. CO 01-1 is used as an accelerator for cold curing polyester resins with hydro-peroxides (MEKP, AAP, CHP) to provide a medium to long potlife. Most unsaturated polyester resins consist of a solution of a polyester in styrene monomer. Polyester Resin Polyester resin cures by an exothermic (heat) reaction created by promoters (cobalt & amine) and activator Methyl Ethel Ketone Peroxide (MEKP). The reaction of polyester will occur at the thickest cross section sending out a wave of heat, which cures resin to a solid glass-like hardness. Cobalt Accelerator CO 01-1 has a metal content of 1 %. Accelerator Applications. Solution of 1% cobalt in solvent mixture used for curing UP resins at ambient temperatures.
