Polyurethane composites and methods of preparing polyurethane composites are described herein. The polyurethane composite can comprise (a) a polyurethane formed by the reaction of (i) one or more isocyanates selected from the group consisting of diisocyanates, polyisocyanates, and mixtures thereof, and (ii) one or more polyols; (b) fly ash comprising 50% or greater by weight, fly ash particles having a particle size of from 0.2 micron to 100 microns; and (c) a coarse filler material comprising 80% or greater by weight, filler particles having a particle size of from greater than 250 microns to 10 mm. The coarse filler material can be present in the composite in an amount of from 1% to 40% by weight, based on the total weight of the composite. The weight ratio of the fly ash to the coarse filler material can be from 9:1 to 200:1.

Provided herein are novel and improved weight coating systems suitable for use with pipes, particularly pipes that are submerged in liquid, such as water, in environments including oceans, seas, marshes, lakes and rivers. The novel coating systems provided herein comprise an aggregate and a polyurethane binder, wherein the polyurethane binder is a two -component composition comprising an isocyanate component and an iso-cyanate-reactive component. The coating systems provided have increased durability, as well as flexibility allowing for efficiencies related to transportation, storage, use and resistance to corrosive effects. Furthermore, the coating systems are cost effective and have minimal or zero impact on the environments in which they are utilized.

This document relates to methods for improving the tensile and elastic properties of cement of an oil well using cement compositions that contain sliding-ring polymer additives. The cement compositions containing the sliding-ring polymer additives exhibit increased stiffness while having a minimum impact on compressive strength, as compared to the same cement without the sliding-ring polymer additive.
