At our facilities located in Hospitalet de l’Infant, Tarragona, we develop and manufacture our polyurethane, epoxy and polyurea esins for all kinds of waterproofing projects and pavement coatings as well as for industrial processes for protection membranes.
As a manufacturer, we do not only develop the products, but we accompany our customers throughout the work process, so that they always have the support of the maximum responsible for the product they are dealing with.
The Rayston brand was born from the need for its own identification for Krypton Chemical products.
A brand that includes all the values of our work: Strong technical knowledge; a lot of patience, so that the result is always the best; and an indestructible commitment with all our customers’ jobs in any phase. These are the pillars on which we rely to create our products and develop our systems. Thanks to these qualities we have been able to create a range of polyurethane, epoxy and polyurea products ideal for your job. All of them under the name of Rayston.
More than simple resins for construction and industrial applications, we create complete solutions.

Waterproofing hot projected
Polyurea Rayston – Purea polyurea for contact with water
This pure polyurea is a product with excellent qualities, even among the hot projected products. It has a high chemical resistance and high mechanical properties. It meets the sanitary criteria of water quality, making it ideal for the waterproofing of both potable and residual water installations. Our pure polyurea is also suitable as a waterproofing for concrete structures or for secondary containment, landfills, tunnels, etc.
Impermax 2K – Hot-applied polyurethane for roofs
Impermax 2K is a two-component polyurethane membrane with moderate reactivity for the application of elastic membranes bridging cracks. It is fast-curing and solvent-free. It is ideal for concrete waterproofing works and roofs.
Impermax Polyurea H – Hybrid polyurea for covers
Impermax Polyurea H is a modified polyurea resin. It is a cheaper alternative to pure polyurea for the coating of concrete structures or roofs. It is slightly slower and more levelling curing than pure polyureas.
Impermax Polyurea H Flex – high flexibility and certification for bridge boards
Within the range of modified polyureas, Impermax Polyurea H Flex is a product of greater elasticity, especially designed for areas subjected to much movement. In addition, it has ETE certification for the waterproofing of bridge decks según ETAG033.
Polyurea Rayston X5 – expandable polyurea
This projected foam reaches up to five times its initial volume and is used in waterproofing systems both as a primer and as a waterproofing membrane on its own, with extra insulation.
