there are ultra lightweight proppant two kinds of classification methods

A wide variety of synthetic resin paint, there are ultra lightweight proppant two kinds of classification methods:
(1) according to the main film forming material classification
Due to the resin is different and each has its characteristics (table 1). Alkyd resin coating production of the largest, fastest growing acrylic resin coatings, amino resin coating, epoxy resin coating, polyurethane coating production is bigger also, this is constitute the five varieties of synthetic resin coating.
(2) the classification according to the oil well fracking with the dispersion medium
Can be divided into three categories of solvent, water type, no solvent (table 2). Solvent-based coating production of the largest, widely used, but because of the need to use a large number of organic solvents, environmental pollution, are being high solid coatings, water type coatings, powder coatings and radiation curing coating gradually replaced. Sometimes call this a few kinds paint coating of saving energy and low pollution, save resources, is the coating product of new variety.
