(Osaka, Japan) merged their unsaturated polyester resin
The [T.sub.[beta]] of amine-crosslinked epoxy is lower than room temperature (-80[degrees]C to -30[degrees]C), while that of our unsaturated polyester resin
is higher than room temperature (~90[degrees]C).
Salla and Ramix (1995) established that the isothermal kinetic analysis through isoconventional adjustment is the best method that offers the most accurate results for unsaturated polyester resin
The average molecular weight of the unsaturated polyester resin
is 2750 g/mol and the equivalent molecular weight / (mol C = C) is 468 g/mol.

Nyacol APE1540 is a dispersion in unsaturated polyester resin
used in polyester and vinylester resins.
Used in the automotive industry for structural components and body panels, sheet molding compound (SMC) is a composite material consisting of chopped fiberglass dispersed randomly in a thermoset polymer matrix, most commonly a styrene crosslinked unsaturated polyester resin
. Automotive designers use SMC to take advantage of its superior strength-to-weight ratio compared to steel, the ability to consolidate multiple parts into one piece, lower tooling costs and use of lower-tonnage presses, and resistance to denting and corrosion.
Figure 1 shows the typical chemical structure obtained with these unsaturated polyester resins
. The reaction of styrene and unsaturated polyester resin
is a free radical chain growth crosslinking copolymerization.
Irving, TX, July 05, 2014 --(PR.com)-- During the last five years, composite applications in the global unsaturated polyester resin
(UPR) market saw good growth, driven by growth in construction, transportation, wind energy, and pipe and tank markets in emerging economies including China and India.
Safas Corporation has been granted a patent for a fluid coating composition comprised of a crosslinkable liquid resin matrix, wherein the resin is an unsaturated polyester resin
containing therein uniformly distributed a crosslinked particulate resin granule containing an inorganic filler and visually differentiable from the matrix resin alumina trihydrate from 0.5%-5% by weight of the composition of an acrylate phosphate obtained by the reaction of a phosphorus penta oxide with hydroxy acrylates and a crosslinking accelerator containing 0.1 to 2.5% by weight of the composition of sodium carboxylate wherein the carboxylate moiety has from 6-22 carbon atoms and 0.1 % -2.5% of dimethyl or diethyl acetoacetamide.
