Neodur® Varnish

mô tả

Description

Neodur® Varnish (gloss or mat) is a two component, acrylic-polyurethane varnish, cured with aliphatic polyisocyanates. It contains UV filters. It is suitable for the protection of cement based surfaces, such as decorative
cement screed.

Fields of application

Protection of decorative cement screed, metallic surfaces, cement, stone, polyester, industrial flooring and constructions in areas adjacent to the sea. It can be applied in two coats as protective varnish after epoxy coatings to
pools, offering durability and UV protection, delaying the caulking phenomenon (especially in swimming pools the gloss version is proposed).

Properties

Long-term UV resistance. Does not become yellowish, with very good gloss retention even after several years. It offers chemical resistance (dilute acids, alkalis) and high mechanical strength and abrasion resistance. Protects against water absorption and enhances the mechanical strength of decorative cement screed. It has strong adhesion, excellent hardness and long lasting durability against weathering. It provides gloss or mat surface maintaining the physical appearance of the decorative cement screed.
