Abstract
Improved hardenable resin compositions useful in forming hard permeable masses in remote locations or zones are provided. The compositions include hardening agents which are non-hazardous to personnel and which are compatible with other components of the compositions. Methods of continuously forming and suspending particulate material coated with the improved resin compositions in gelled aqueous carrier liquid are also provided.
Claims20
In an improved hardenable resin composition comprising a hardenable polyepoxide rein, one or more substantially water immiscible diluents present in said resin composition in amount sufficient to lower the viscosity thereof to a desired level, and a hardening agent:
- wherein the improvement comprises said hardening agent consisting of the adduct formed by reacting an aliphatic amine with a condensation reaction product of epichlorohydrin and Bisphenol A wherein the molar quantity of amine is at least about 2 times the molar quantity of the condensation reaction product.
The composition of claim which is further characterized to include an aqueous liquid in which said hardenable resin composition is dispersed.
In an improved composition useful in forming a hard permeable mass in a remote location comprising:
- an aqueous liquid;
- a gelling agent comprising at least one hydratable polysaccharide;
- a resin composition which will subsequently harden comprising a hardenable polyepoxide resin, substantially water immiscible reactive and non-reactive diluents present in said resin composition in amounts sufficient to lower the viscosity thereof to a desired level and a hardening agent;
- particulate material;
- and
- one or more surface active agents for promoting the coating of said particulate material with said resin composition:
- wherein the improvement comprises said hardening agent consisting of an adduct formed by reacting an eliphatic amine with a condensation reaction product of epichlorohydrin and bisphenol A wherein the molar quantity of the amine is at least about 2 times the molar quantity of the condensation reaction product.
In an improved method of continuously forming and suspending consolidatible resin composition coated particulate material in a gelled aqueous carrier liquid comprising admixing continuous streams of said gelled aqueous carrier liquid, uncrated particulate material, a resin composition which will subsequently harden and one or more surface active agents whereby said particulate material in continuously coated with said resin composition and suspended in said gelled aqueous carrier liquid, said resin composition being comprised of a hardenable polyepoxide resin, one or more substantially water immiscible diluents present in said resin composition in amounts sufficient to lower the viscosity thereof to a desired level and a hardening agent:
- wherein the improvement comprises said hardening agent consisting of the adduct formed by reacting an aliphatic amine with a condensation reaction product of epichlorohydrin and bisphenol A wherein the molar quantity of the amine is at least about 2 times the molar quantity of the condensation reaction product.
