Table 1: Properties of polyester resin Characteristics Polyester Resin Flexural Strength Good Tensile Strength Good Elongation % Good Water Absorption Good Hardness Good Pot Life 4-7 Minutes Working Time 20-30 Minutes Above Waterline Yes Below Waterline Yes Major Construction Yes General Repairs Yes Shelf Life 18-24 Months Catalyst MEKP Cure Time 6-8 Hours Table 1.
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.
The catalyst, MEKP, was then added to the resin at a concentration (by weight) of 1% and mixed for 3 min.
We also ignored the polyester and MEKP used in this work, because the amounts used were insignificant compared to the amounts of rubber tire dust and rice husks that were used.
The free radicals would be generated when the mixture of hemp fibers and the UPE resin containing styrene and MEKP was heated, resulting in the crosslinking and polymerization among NMA-treated fibers, styrene, and the UPE backbones.
Abcure S-40-25 sprayable 40% emulsion of BPO in water recommended as an alternative to MEKP in applications that can tolerate introduction of water with the catalyst.
46:1 36 MEKP Co naphtenate 150 ppm Cu octoate oPA:MA:1,2PG = 0.
It is most appropriate for resin systems that employ MEKP or acetyl acetone peroxide (AAP) cures.
Even though there are several controversial interpretations about the origin of these exothermic peaks [10-15], the first peak can be attributed to the polymerization initiated by a redox decomposition of methylethylketone peroxide (MEKP), and the second one to the polymerization initiated by the thermal decomposition of MEKP at high temperatures.
