Abstract TACTIX 556 is a multifunctional epoxy novolac resin. Its dicyclopentadiene structure has extremely low average molecular polarity, a feature critical to low moisture absorbance. This datasheet provides information on composition, physical properties, and tensile properties. Filing Code: P-26. Producer or source: The Dow Chemical Company, Dow Plastics.

Low-density phenolic syntactic foams with different volume percentages of microballoons were processed and their mechanical performance has been evaluated in terms of tensile, flexural, compressive and the corresponding specific properties. Tensile and flexural strength increased with volume fraction of microballoon and optimized at 72–74 percentage by volume of microballoon. Both the properties decreased with further addition of microballoon. The corresponding specific properties also manifested a similar order. Compressive and specific compressive strength decreased with increase in microballoon volume percentage. The flexural and compressive modulus values followed the same trend as the strength values. The properties of phenolic syntactic foams were compared with syntactic foams based on an addition cure phenolic resin, Propargyl Ether Novolac resin (PN). The mechanical properties of the latter were inferior to those of phenolic syntactic foams. The morphology of the failed samples as examined by SEM showed that failure occurred by a combination of matrix and microballoon failure at low microballoon loading whereas it occurred by microballoon cracking and resin to microballoon debonding at high concentration of filler. The dynamic mechanical analysis of phenolic and PN resin syntactic foams showed a higher use temperature for PN system in comparison to phenolic.

The purpose of this study is to examine the effect of adding novolac resin by different volumetric percentages to concert as a light weight aggregate In addition to the economic feasibility of the use of these concrete in the field of build and construction .they investigated tht the compression strength, thermal conductivity, acoustic insulation and densities. The results showed ultimate compression strength and acoustic insulation by melting novolac and added to the cement and sand as a polymer concrete in the hot state (by melting novoac >90c).However added novolac resin as aggregate in the cold state to the concrete increase thermal conductivity and increasing compression strength and acoustic insulation .This results gained by chemical interaction of novolac and cement.
