Intrinsically modified self-extinguishing fire-retardant epoxy resin using boron-polyol complex

Flame Retardant Luffa Fiber Reinforced Composites with Epoxy Resin Matrices

In current years composites have concerned considerable importance as a potential operational material. Low cost, light weights, high specific modulus, renewability, and biodegradability are the most basic & common attractive features of composites that make them useful for industrial applications. Luffacylindrical locally called as “sponge-gourd” is one such natural resource whose potential as...

Polyol from castor oil and epoxy resin for PU Coatings

Novel reactive polyols were synthesized via modification of castor oil, a renewable agricultural raw material with epoxy resin and triethylamine as a catalyst. This polyol was used for synthesis of polyurethane coating. Coating formulations were developed by reacting polyol with aromatic adduct, aliphatic adduct and castor oil based adduct in different NCO/OH ratio. All coating composition syst...

Mechanical and Thermal Properties of Chemically Modified Epoxy Resin

Diglycidyl ether of bisphenol-A (DGEBA), having number average molecular weight (Mn) 375, was modified by incorporating the hydroxyl terminated polybutadiene (HTPB) based prepolymer using isophorone diisocyanate as a coupling agent. To increase the compatibility between the epoxy resin and HTPB part, polar groups were introduced in the later to achieve physical and chemical interactions between...

Experimental data on the properties of polymer-modified cement grouts using epoxy and acrylic resin emulsions

The use of additives to improve the quality of cement grouts is crucial for civil engineering, especially in foundation construction. This article presents experimental data concerning the compressive strength, elastic modulus, bleeding and injectability of microfine cement grouts modified with epoxy and acrylic resin emulsions. Strength properties were obtained at different curing ages. For fu...
