Table of Contents Polyurethane for resin floor History of Polyurethane Polyurethanes were invented in 1930s by Professor Dr. Otto Bayer and his coworker in Germany. Early work focused on the production of fibers and flexible foams and PUs were applied on a limited scale as aircraft coating, during World War II they were used vastly […]

Table of Contents What is PMMA Flooring? PMMA (Polymethyl Methacrylate) is a transparent thermoplastic synthetic resin. This plastic is an alternative to glass. PMMA is also known as acrylic, acrylic glass. PMMA is used for many different proposes especially in making products like as illuminated signs, craft and aircraft windows, building canopies, eyeglass lenses, car […]
Among the methods of repairing concrete structures is an injection of epoxy resin and polyurethane. Resin injection: Resin injection is used to repair only concrete with cracks or spots, joints, and wet cracks. Two main methods are used to improve concrete using the resin injection technique: A – Epoxy resin: Epoxy resins are solid treated with […]
Differences between polyurethane flooring and epoxy flooring In general, polyurethane and epoxy flooring are the most widely used coating materials in Iran and even globally, but the differences between the two types of flooring have sometimes led to very different uses. As a general comparison between the properties of the two floors, it should be […]
The name epoxy comes from the fact that the molecules in this system of resins contain carbon-oxygen, which is why they are called epoxies. The oxygen atom is attached to two carbon atoms, which are attached in other ways. Therefore, the simplest type of epoxy is ethylene oxide, the reactivity of epoxy resins depending on […]
Polyurethane dispersion resins (PUDs) A well-known approach within the manufacture of water-primarily based polyurethane dispersion resins is getting ready a prepolymer with the very last isocyanate institution, which modifies the polyol withinside the chain shape carboxylic acid purposeful institution. This fabric with the 0.33 form of amine in Water is dispersed to shape ionic centres […]
