Visco-Rite™ 70Paste
is a non-crystalline pure homopolymer polyisobutene paste.
Visco-Rite™70Paste is a viscoelastic high-performance corrosion barrier material to protect corroded carbon steel, stainless steel, ductile iron and non-ferro metal substrates. The material is specific designed for submersed and immersed services from -45 up to +70°C (-49 up to 158°F).
The alternate for primerless wax, butyl, bitumen tape coatings.
Objective
The objective is the provision of aboveground paint coating solutions that are friendly to humans and the environment and unique in their composition and effectiveness on damp surfaces. Allter® aims to supply a universal next generation primer that is simply the best for long-term corrosion protection of durable assets from a holistic, TCO (Total Cost of Ownership) point of view, with an optimum lifespan of 15 years at up to 230 degrees Celsius.
