Painting over polyurethane – “Product widely used in industry, of many applications, it is used to make flexible foams, sealing resins, adhesives and coatings”. Do you know what this definition corresponds to? If not, now we tell you: its polyurethane. In today’s article we will talk about one of its derivatives: polyurethane paint. In this way we will increase the number of articles dedicate to the different kinds of painting that we can find. And in this way you will be able to expand your knowledge in these matters. You can already consider yourself an expert in epoxy paint, decorative painting or industrial painting. So today we have to learn about a new class: polyurethane paint. These polyurethane products are able to create very hard and elastic layers. With a brilliant effect and a great resistance to chemical products and to the elements.
This paint takes its name from urethane, which is a very sophisticate engineering product. It has many more advantages than other kinds of plastics. As it has very interesting physical properties such as: high wear resistance, good elasticity, excellent ability to withstand weights and large loads without undergoing deformations, or a high resistance to impacts. Painting over polyurethane contains powerful and somewhat dangerous thinners. So you have to be careful in your application. Try to have adequate ventilation, wear eye protection and avoid prolonged contact with the skin. It is very important that you do not approach this paint to any flame or stove. As it is a very flammable product. In addition, it is very difficult to eliminate. So we should consult the manufacturer’s instructions to know which procedure to follow.
Like the epoxy floor paint, it has a glossy finish. Provides a protective layer in floors, walls, artistic projects and other surfaces. There are different kinds of polyurethane paint. First of all we have acrylic painting over polyurethane, mainly used in cars or water towers. In general, on surfaces where friction is limited. And there is possibility of abrasion. It has different finishes and can be apply with spray gun, spray can or brush. Then we have polyurethane polyester, which offers a lot of protection since it is resistant to stains, abrasion and chemicals. It applies, for example, in airplanes or ships. It also has different finishes and can be applied by spray gun, spray can or brush. There are also more specific types of polyurethane paint for concrete surfaces.
