is a non-crystalline pure homopolymer polyisobutene.
Visco-Rite™ 70HB is a viscoelastic fibre-reinforced 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) and complies to ISO 21809-3: 2016 and ISO 12944: 2018 with a suitable mechanical protection.
The alternate for primerless wax, butyl, bitumen tape coatings.
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.
