The present disclosure provides to a novel flame retardant resin, wherein the resin is a reaction product of an epoxy material, a curing agent, and a partially esterified tannic acid of formula I,

Flame retardant resin

Methods and systems for treating emissions during a cured-in-place pipe (CIPP) closed molding process in which a resin-impregnated fibrous material is placed within an existing fluid conduit and cured in situ to seal an opening in the conduit. Such a method includes capturing multi-phase emissions released by a resin-impregnated fibrous material during curing thereof in a CIPP process, accumulating the multi-phase emissions, condensing at least a water portion of the multi-phase emissions, and treating vapor constituents of the multi-phase emissions.

Methods and systems for treating emissions released during closed molding processes

The present application generally relates to epoxy/tannin reaction product compositions, and methods of making and using the epoxy tannin reaction product compositions. The epoxy/tannin reaction product compositions are hardened thermosetting polymeric materials, are substantially homogeneous and substantially free of visible clumps, and have a glass transition temperature of at least 140&#xb0; C.

Epoxy tannin reaction product compositions

Disclosed herein are flame retardant materials, and in particular materials and processes for phosphorylating materials for flame retardant applications.
