Epoxy resins are also used for decorative flooring applications such as terrazzo flooring, chip flooring, and colored aggregate flooring. Epoxies have been modified in a variety of ways, including reacting with fatty acids derived from oils to yield epoxy esters, which were cured the same way as alkyds.
Epoxy moisture control systems are chemical barriers that are used to prevent moisture damage to flooring. Excessive moisture vapor emissions in concrete slabs can mean significant, expensive damage to a flooring installation. Hundreds of millions of dollars are spent annually just in the United States to correct moisture-related problems in ...
Various epoxy resin systems have been formulated as varnishes or floor finishes whereby two components are mixed directly before application. [18] Sometimes, the two parts are of equal volume and referred to as 1:1 but not always, as 2:1, 3:1, 4:1 and even 5:1 mixing ratios are commercially available.
Epoxy resin is two times stronger than concrete, seamless, and waterproof. [citation needed] Accordingly, it has been mainly in use for industrial flooring purposes since the 1960s. Since 2000, however, epoxy and polyurethane resins are used in interiors as well, mainly in Western Europe.
The four primary ingredients are the resin (or binder), solvent which may be water (or solventless), pigment(s) and additives. [example needed] [70] [71] Research is ongoing to remove heavy metals from coating formulations completely. [72]
In the epoxy industry it is often referred to as PACM, short for para-diaminodicyclohexylmethane. It is used as a curing agent for epoxy resins [1] It finds particular use in epoxy flooring. [2] Another use is to produce diisocyanates, which are precursors to polyurethanes. The mixture is a colorless solid, but typical samples are yellowish ...
