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 reaction occurs at ambient temperature.
Polyurethane can be produced in various forms such as foams, films, elastomers, powders, liquids, and emulsions.
What is polyurethane resin?
A low-viscosity one-component material made of liquid polyurethane is an insulating and waterproofing material that creates a highly elastic membrane due to moisture action.
Polyurethane resin resistance
Polyurethanes have excellent resistance to impact wear and cracking, and one of their characteristics is fast and complete curing at room temperature.
Aliphatic polyurethanes are more expensive than aromatic types. That is why aromatic types and epoxy samples are used in primers, base paints, and interface coatings. At the same time, aliphatics are specific to the final coating.
The use of protective coatings to prevent corrosion in steel structures with primers and base coatings of epoxy systems are examples of critical applications of polyurethanes.
Another case is the floor covering systems in which a variety of base coatings can also be used. Sometimes a final urethane coating is sufficient for the last floor layer.
Single component polyurethane resin
Single-component polyurethane resin adheres firmly to various surfaces to form a highly elastic and durable membrane.
There is no need to use additional solvent because it contains minimal solvent (XYLOL).
This product contains pure hydrophobic elastomeric resin made of polyurethane and a unique mineral filler.
These fillers offer products with high chemical resistance, UV resistance, mechanical and thermal resistance.
White and gray may be used entirely in outdoor performances.
Two-component polyurethane resin
Polyurethane resin flooring is one of the two-component resins used as a paint base and hardener in the paint industry. This resin is used without any solvent.
Polyurethane molding and modeling resins with outstanding mechanical properties and excellent flexibility and non-shrinkage and shrinkage during the molding process of the parts allows the construction of molds and mother molds with very high sensitivities.
Significant reduction of mold manufacturing costs, an increase of speed, variety in achieving the desired properties in molds and models, and production of low-volume parts are the prominent features of polyurethane resin floors in the manufacture of mold models and functions.
Application of two-component polyurethane
Polyurethane coating is two-component and based on polyurethane resin, due to abrasion resistance and high mechanical resistance and stability against chemical agents, for coating concrete, asphalt, and metal surfaces in places where high mechanical strength of the floor is required. It can be used. The properties of this coating are similar to epoxy coating, with the difference that this coating has better resistance to sunlight compared to epoxy baroque. Also, this material can be used as flooring in health, industrial and military centers and gyms.
Single component polyurethane
One-component polyurethane paint, also called cold paint, is made based on resin.
This floor covering creates a glossy and polished layer on the floor that has good resistance to abrasion, erosion, sunlight (UV), and acid rain, so it is suitable for open spaces such as open parking lots and playgrounds as well as for lanes. They are street drawers and are used in spaces where friction and impact are higher than in other places.
To use polyurethane paints, the desired surface must be free of any contaminants such as dust and oil; Therefore, before using polyurethane paint, the desired surface must be cleaned of any contamination.
Also, all cracks, seams, and corrosion should be removed with a suitable liner to create a uniform surface to start work.
Single-component polyurethane paint is less thick than two-component paint; As a result, their drying time is shorter, and they form quickly and hard even at low temperatures.
This flooring has excellent adhesion and easily creates a suitable coating on surfaces such as metal and concrete.
