Multi-thickness elastomer polyurethane membrane for electrically insulating flexible coating

Polyplex 7 for electrical insulation www.denber-paints.co.il

Two-component polyurethane “rubber” coating. 100% solids 150% elongation. Multi-thickness and powerful for electrically insulating coating for durability in particularly harsh conditions including direct exposure to sun and rain, is especially suitable as a protective upper coating for electrical insulation of electrical systems and electronics exposed to water and moisture to prevent short circuits, as well as systems that are in displacement for fixation and protection from physical injury that can be caused by vibrations and mechanical blows.

POLYFLEX 7 FLEXIBLE ELECTRIC ISOLATION COAT – for absolute sealing and electric isolation.

A unique coating of a particularly strong flexible membrane, the abrasion-resistant coating has a unique molecular structure with an extremely high amount of chemical bonds that creates an impenetrable chemical matrix, which seals completely against the passage of gases and water and allows elongation and contraction according to temperature changes. Strengthens the existing infrastructure and gives a smooth, washable and very strong layer suitable for electrical insulation of voltages and high currents. Insulates electricity and prevents the passage of electricity over the expected surface to prevent electric shock and/or short circuit.
