• Resumen

  • Unsaturated polyester resins in styrene as comonomer solvent gels to a thermoset stageby network formation due to free radicals produced by the redox reaction between cobalt octoate (promoter) and methyl ethyl ketone peroxide (MEKP) as initiator. Gel times can be reduced or enhanced by the use of N,N-Dimethyl aniline (DMA) or pyridine respectively. The technique of hand lay-up for producing glass reinforced fiber (GRF) is described.
