The Preparation and Characterization of a Novolac Cured Epoxy-Clay Nanocomposites

, 2006
Intercalated or exfoliated nanocomposites were composed by the novolac cured epoxy and one of three different kinds of layered silicates, such as montmorillonite (PK-802), saponite (Semecton-SA) and nontronite (PK-805).

Characterization of a novolac resin substituting phenol by ammonium lignosulfonate as filler or extender

BioResources, 2007
In this work two types of lignin-novolac resins have been formulated, partially substituting phenol by softwood ammonium lignosulfonate as filler or extender (methylolated) to study the viability of that substitution when resins will be employed as ...
