Which adversely affect their overall durabihty by imposing severe constraints on the processing cuid design parameters to limit their end-use apphcations. [Pg.28]

With all these ideas in mind, an attempt was made to obtain high performance epoxy resins with superior impact strength, thermal stability, flame retardancy and corrosion and fouling resistance by simultaneous incorporation of silicone and phosphorus moieties into the epoxy skeleton. The present work discusses the development of novel phosphorus-containing siliconized epoxy resins, the improved characteristic properties of the cmed resin systems md their nanocomposites as well. The developed phosphorus-containing siliconized epoxy resins offer multi-faceted properties ideally suitable for high performsmce apphcations. [Pg.28]

The LOI behavior of phosphorus-containing siliconized epoxy followed the same trend as that of siliconized epoxy system. Epoxy and siliconized epoxy materials cured with the phosphorus diamine curative exhibited the maximum LOI value of 42, which maybe due to the consequence of the char enrichment of phosphorus and the char protecting effect of silicone to exhibit the synergistic effect of both silicone and phosphorus on LOI enhancement [50-54]. Thus simultaneously incorporating silicone and phosphorus into epoxy resin would render these epoxies as flame-retardant polymers and can be rated as the best flame retardant material. [Pg.33]

In a study of dental silicate cements, Kent, Fletcher Wilson (1970) used electron probe analysis to study the fully set material. Their method of sample preparation varied slightly from the general one described above, in that they embedded their set cement in epoxy resin, polished the surface to flatness, and then coated it with a 2-nm carbon layer to provide electrical conductivity. They analysed the various areas of the cement for calcium, silicon, aluminium and phosphorus, and found that the cement comprised a matrix containing phosphorus, aluminium and calcium, but not silicon. The aluminosilicate glass was assumed to develop into a gel which was relatively depleted in calcium. [Pg.369]

Simultaneous incorporation of silicone- and phosphorus-modifiers in di- and tetrafunctional epoxy resins improved their thermal, flame, environmental, corrosion and fouling resistant properties compared to commercially available epoxy resins that are currently used in the field, where high corrosion, fouling and flame resistance are of primary concern. This invention cilso involved the synthesis of novel sulphone, sihcone and phosphorus skeletcil modified tetrafunctional epoxy resins, which served as matrices for the fabrication of nanocomposites containing POSS nano-reinforcement which exhibited high performance characteristics ideally suited for the fabrication of advanced...
