Provide customers and asset owners with the opportunity to optimize budgets, considering the ease of application in construction or maintenance by adding a 30 Year Warranty and Life Expectancy of over 60 Years

Applications include Renewable Energy Structures, Processing Plants, Onshore and Offshore Gas and Oil Pipelines, Petrochemicals, Refineries, Maritime Installations, Water Networks, Basic Sanitation, Civil Structures, etc. 

Features and Advantages

  • Products with no shelf life in storage and ready to use - no aging.

  • These products can be applied on substrates with reduced surface preparation (degreased, cleaned and dried), in accordance with the requirements of ISO 8501-1 Grade St 2, roughness being irrelevant.

  • Manual application, easy and fast. Does not drip, permanently flexible and homogeneous thickness.

  • Totally impermeable to water and oxygen. 

  • It has high dielectric strength.

  • Remarkable adhesion and self-healing characteristics.

  • Environmentally friendly products with a life expectancy of over 60 years. 

  • 30 year warranty.
