What is Polyurethane Floor Coating?
The latest in industrial technology and innovation.
The polyurethane system is made up of various polyol subcomponents (polyether, polyester) and as a rule, requires catalysts in order to cure rapidly. An advantage of this system is that the catalyst can be adjusted to control the reaction profile to fit the application. Some applications require a smoother finish, but if the system gels too fast, a rough orange peel surface will result.
Fast and effective systemsPolyurethane floors are mostly spray applied but can also be cast and sometimes hand-rolled. Typically, the "gel" time for spray applied polyurethane systems ranges from 15 - 30 seconds. It is this fast setting time that provides many of its advantages. For example, some applications require the coating to flow into hard to spray areas or corners and so need a few extra seconds before gelling.
Polyurethane applicationsA polyurethane floor coating can be applied to virtually any required thickness in one application. They are not usually multi-coat systems. This results in very fast applications and turnaround times.
They also have zero taste impact - very important when assessing potable water approval because many other products do impart a "plastic" taste when it comes to potable water.
Not only do the unique curing features of premium polyurethane floor coatings drastically reduce the amount of time it takes to actually line the tank, they also cut the required curing time by over one third.
Premium polyurethane floors can also be sprayed or poured in remote locations, while still retaining the fantastic protection required for field joints and internal connections commonly found in the pipe industry.
They can also be designed to have densely cross-linked characteristics to dramatically resist chemical attack.
Water, wastewater and sewerage
Specially formulated, premium 2:1 polyurethanes offer far superior protection than standard systems, giving excellent chemical, impact and abrasion resistance, improved adhesion, and resistance to cathodic disbondment and undercutting.
The benefits of elastomeric polyurethane floors
Rhino Linings elastomeric polyurea and polyurethane coatings currently protect a variety of structures, including storage tanks, oil and gas pipelines, water and wastewater, marine vessels, and commercial facilities. The applications have been successful because of:
