Taking advantage of the unique environment of activity in polyurethane chemistry, FLEXPUR developed polyurea technology to protect materials in a wide variety of environments, such as industrial, commercial and maintenance. FLEXPUR thus presents its customers with a set of solutions capable of meeting the specific needs of each project.

We manufacture our own solutions and are able to provide technical support from the project phase to the execution on site, as well as the possibility of appropriate training for our customers, as evidenced by our "Technical guide to the application of POLYBLOCK", which is available for professional applicators and can be requested here.

Protective Coatings

POLYBLOCK products are two-component, solvent-free polyurea systems formed from the mixture of two highly reactive components (isocyanates and amines) in liquid form.

The final product is a solid, completely continuous membrane, without joints or overlaps, with high density and excellent mechanical properties both in terms of tensile strength and abrasion resistance as well as flexibility. It is also characterized by its high adhesion to most substrates.

POLYBLOCK products are indicated for use in waterproofing surfaces (such as roofs, pools, tanks, reservoirs) and protecting a wide variety of structures, especially where high chemical and mechanical resistance is required.

As a complement to the range of products and depending on the purpose of application of the polyurea and the type of substrate, we offer integrated protection solutions, which include primers, polyurea membrane and top coats.
