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 […]
Polyurethanes are a collection of flexible polymers with top-notch properties. Therefore, designers and experts withinside the coating enterprise can use those compounds in several packages. There are numerous examples of the various packages of those compounds, including clean coatings for single-layer roofing coatings and colours to mark pedestrian crossings. Polyurethanes have top-notch resistance to effect […]
It sells polyurethane resin for those who intend to use old flooring such as tiles, ceramics, etc., discarding these old and unsuitable items instead of using polyurethane resin as an industrial resin flooring for homes . Not only is it fantastic, but its benefits and applications are many. Polyurethane resin means huge molecular chains that […]
Polyurethane (PU) is the generic name for many chemicals that have a urethane bond. The urethane bond is formed by an additive reaction between an isocyanate group and an active hydrogen compound such as a hydroxyl group. Isocyanate groups are highly reactive, and therefore their response does not require an increase in temperature, and the […]
Polyurea resin flooring Polyurea is an elastomeric product resulting from the reaction between a compound of isocyanate and a mixture of synthetic resins. It is one of the most durable types of protective coatings in the world, which due to its high chemical, physical and thermal resistance, is widely used in anti-corrosion coatings industries of […]
In the continuation of the previous article, we want to explain the steps of applying polyurethane domestic resin flooring after surface preparation: Apply polyurethane floor primer layer At this stage, polyurethane-based primers, which have a very low viscosity compared to other materials, are applied as a primer and the initial layer of polyurethane flooring. Using […]
Resin flooring is a good option for a variety of industries (food industry, pharmaceutical industry, machine-building factories, etc.); Because these floors are very stable and safe and at the same time have a long life. In addition to their appearance, these floors are easy to clean and show good resistance to damage. In the following, […]
