SETATHANE D E 2767 is applied in combination with aromatic polyisocyanates based on diphenylmethane diisocyanate as binder for solvent-free two-component polyurethane coatings with high chemical resistance for concrete and other porous substrates, fillers, sealing compounds and synthetic resin mortars. SETATHANE D E 2767 is suitable for the formulation of coatings, mortars and sealers with high chemical resistance. Coatings formulated with SETATHANE D E 2767 generally exhibit outstanding resistance to organic and inorganic acids, alkalis and solvents. Over-cross linking of 50 % and more is usual. This allows a wide-ranging variation in flow and chemical resistance. To ensure blister-free curing, SETATHANE D E 2767 requires the addition of hydrated lime in accordance with DIN EN 12 518 (or cement if necessary) as a CO2 scavenger. In certain cases where the film thickness is less than 100 μm, there is no need to add hydrated lime.

SETATHANE D 1155 is applied in combination with e.g. SETATHANE D 1145 and 1150 in the formulation of coatings SETATHANE D 1155 is not recommended as a sole binder. Because of its low viscosity, SETATHANE D 1155 is especially suitable for combination with SETATHANE D 1145 and 1150 in the formulation of solventfree, self-leveling polyurethane coatings of low viscosity. Desmodur® VL or VL 50 are normally used as hardener.

ROSKYDAL E 70 is a flexibilising resin for wax-free polyesters, UV-curing styrene systems and spray, roller and knifing fillers. Even in a ratio of 6 : 4, clear or pigmented combinations of ROSKYDAL 500 A and ROSKYDAL E 70 have excellent scratch resistance and gloss. This mixing ratio yields highly flexible coatings and improves the polishability of films based on ROSKYDAL 500 A. ROSKYDAL E 70 is also suitable for use as a flexibilizer in photo-polymerizing ROSKYDAL systems and in clear coats, roller primers and highly filled roller fillers based on ROSKYDAL 300/1. ROSKYDAL E 70 is a highly effective flexibilizer. The systems to which it is added are easier to sand because they abrade more readily. Adding larger amounts of ROSKYDAL E 70 to spray fillers based on wax-free polyesters such as ROSKYDAL 500 A or 620 yields excellent adhesion on medium-density fiberboard, metal car body components and some plastics. ROSKYDAL E 70 can also be used to flexibilize amine-accelerated grades such as ROSKYDAL K 14 M, K 36 and K 40 T.

RESYDROL AZ 6710W/41WA does not contain organic co-solvent and can be used as sole binder for (trim) paints, primers and wood-stains.
