  • Patent number: 5321062
    Abstract: A substituted alkoxy benzene having the formula ##STR1## wherein R, R.sub.1, R.sub.2 and R.sub.3 are each a hydrocarbon radical having from 1 to 8 carbon atoms and x is 0 or 1 is provided. The substituted alkoxy benzene is very useful as a wetting aid for enhancing the ability of hardenable polyepoxide resin compositions to coat and bond to material (e.g., particulate material) in high temperature applications. The substituted alkoxy benzene does not significantly accelerate the curing rate of the resins. A polyepoxide resin composition for coating and bonding to a material, a composition useful for forming a hard permeable mass in a remote location and a method of continuously forming and suspending consolidatible resin composition coated particulate material in a gelled aqueous carrier liquid and transporting the coated particulate material to a remote location where the material is consolidated are also provided.
