Polyurethane Coating
Polyurethane Coating
A polyurethane coating is a protective layer of polyurethane that is placed to the surface of a substrate.
Corrosion, weathering, abrasion, and other degrading processes are all protected by these coatings.
MapeFloor Finish 415 may be applied in a single coat with a roller or with a straight steel or rubber trowel. If the product is
applied with a roller, it is recommended to apply it with crisscross strokes and to make sure it is applied evenly to get a
good, attractive finish. When applying the product with a trowel, pour it onto the substrate and spread it out over the broadcast surface of MapeFloor PU 410 down to a feather edge.
After spreading the product, you may also back-roll with a
short-pile roller to eliminate any marks left by the trowel. When applying the product with a rubber trowel, its
consumption rate and hiding power will be slightly lower and the surface will be slightly rougher compared with
application using a steel trowel.
If MapeFloor Finish 415 hardens in surroundings with more than 60% R.H. in the air the surface may have a slight orange-peel effect finish on the film of coating. This will have no effect on its performance characteristics.
Polyurethane is a form of polymer that has a carbamate chemical component group attached to it. This polymer substance is also thermosetting, which means that when heated, it burns rather than dissolves.
Another feature of polyurethane coatings is their adaptability. Glossy, muted, opaque, or transparent coatings can all be created.
While polyurethane coatings may appear to be comparable to other coatings (such as epoxy), they have certain unique characteristics that make them appropriate for specific applications.
Polyurethane floor coatings are appropriate for a variety of applications, including airports, hospitals, car parks, freezing chambers, malls, and other busy commercial locations, thanks to their characteristics and properties.
Water-based polyurethane coatings that have been specially developed are also non-flammable. This property enables them to be employed in circumstances where combustion is a possibility.
Many polyurethanes coatings cure without the need for extra processing.
They are easily applied and heal when exposed to atmospheric moisture. On a base material, they can be sprayed or rolled.
Polyurethane coatings are applied to a variety of surfaces, including wood floors, metals, and over other coatings.
