Polyurea coatings

By the term elastomer are indicated natural or synthetic substances that can undergo elastic deformation, such as to elongation by summarizing their size once a situation of rest is recreated.
The elastomers are part of the polymer (Polyurea coatings) and are divided into two main classes:
• thermoplastic elastomers
• thermoset elastomers
Thermoplastic elastomers, introduced into the market, are generally copolymers of styrene and butadiene, polyolefins and co-polyesters. Once hardened, if brought to the glass transition temperature, they can be reshaped.
The thermoset elastomers instead are produced by linking chains of different polymers through chemical reactions in two-component and / or hygrosetting systems.

Products
- Pavaflex Mono
Monocomponent polyurea coatings with medium modulus, overcoatable.  It is suitable for sealing of control / withdrawal joints of industrial floors, joints facades or cracks even in presence of weak aggressive chemicals, subject to small movements.
It is suitable for civil and industrial environments, and for the food, mechanical and construction industries.
- PAVAFLEX / E
Pigmented two-component product polyurea coatings, modified with special elastomeric, solvent-free.
It is suitable for coatings for flooring, concrete structures, tanks (water supply, sewage and sewer), steel structures which are subjected to mechanical stress; good chemical resistance to acids and bases and dilute to saturated hydrocarbons.
Pava- Elastic 570
Two-component product, modified with elastomers, pigmented solvent-free with low elastic modulus.
It is suitable for sealing of construction and / or structural joints which are not subject to excessive movement of the structure but also heavy goods traffic.
- Epotar Pava TN2
Product based on synthetic resins, modified with special elastomers and constant in the quality of the distilled fraction; sealant product with appropriate fluidity, suitable for the casting and sealing of cracks and cuts on cement. Is is also suitable as coating in wastewater treatment plants and sewerage systems (dilute and little aggressive solutions).
It is resistant to direct contact with sea water and water solutions which are not particularly aggressive.
- Pava Joint 1000
Two-component polyurea product, modified with elastomers, pigmented, solvent-free, low elastic modulus. Elastic product with considerable flexibility for construction and / or structural joints. High features of crack bridging that is able to contain the formation of cracks even when the support is subjected to structural tensions.
- Ultrapol Pava
Pigmented two-component polyurethane product, made with special anti-wear additives; the product
provides resistance to light (UV) with low yellowing and no chalking.
It is suitable  to coat outdoor concrete or beton surfaces (Topcoat)  And it is applicable as the final layer of epoxy coatings to keep brightness and resistance to light and avoid chalking  of the underlying coating.
