Highly resistant glossy clear varnish specially formulated for the long-term protection of surfaces against wear, abrasion, chemical spills, and weathering.
RD-Hydrograff HP is THE solution to protect surfaces that are subject to severe strains. Whether it is a floor, industrial equipment, furniture, etc. RD-Hydrograff HP has unmatched performance. For indoors or outdoors! This varnish can be applied directly on most kinds of paint and sometimes directly to the surface.
Highly resistant varnish specially formulated for the long-term protection of surfaces against wear, abrasion, chemical spills, and weathering.
RD-Hydrograff HP Clear is a two-component aliphatic polyurethane topcoat for indoor and outdoor use. After drying, the coating creates a hard flexible and wear resistant film that can be used for decorative and protective purposes. It is appropriate for application on concrete and wooden floors or objects, walls, steel and non-ferrous metals with a primer, etc. It provides very good resistance against humidity and very good outdoor durability.
RD-Hydrograff HP Clear is water-based, easy to handle and has no fire risks.
RD-Hydrograff HP Clear is formulated with high quality raw materials and provides a very good chemical resistance, a very good resistance against abrasion and solvents, a very high hardness (Taber abrasion: weight loss after 1000 cycles /CS 10 = 0.060 g); while keeping flexibility in its film that will avoid future cracks.
RD-Hydrograff HP Clear can provide very high levels of anti-corrosion protection surpassing traditional three coat systems when combined with RD-Monoguard!
It is also used as transparent anti-corrosion system when combined with RD-Monoguard Clear.
RD-Hydrograff Clear High Gloss can be used as an anti-graffiti protection on top of various kind of surfaces.
Various surfaces like plastics, concrete, cement, wood, metal, when primed accordingly.
