SETATHANE D E 2656 is applied in combination with Desmodur® VL as a binder for chemically resistant coatings. SETATHANE D E 2656 is suitable for the formulation of coatings and mortars with high chemical resistance for food and beverage industries. Coatings formulated with SETATHANE D E 2656 / Desmodur VL generally exhibit very good resistance to organic and inorganic acids, alkalis and solvents. Overcrosslinking of 500 % is usual. This optimizes chemical resistance and flow. To ensure blister-free curing, SETATHANE D E 2656 requires the addition of hydrated lime and/or cement as a CO2 scavenger.

SETATHANE D 1160 is applied in combination with solvent-free, predominantly aromatic polyisocyanates, as a binder for flexible floor coatings. It is the most suitable co-reactant for SETATHANE D 1160 is Desmodur VH 20 N. Other polyisocyanates such as Desmodur VL are also suitable but the compatibility must be tested in each case. SETATHANE D 1160 can be used in the formulation of flexible floor coatings. Coatings based on SETATHANE D 1160 and Desmodur VH 20 N are characterized by their high flexibility and good mechanical strength.

ROSKYDAL K 12 P is a binder for highly filled knifing fillers and stoppers for marble and stone. Fillers based on ROSKYDAL K 12 P cure fully whether applied in thin or thick coats. They are used in applications requiring hard adhesives and fillers. Formulation Combinations of talc, dolomite/calcite and powdered barytes with low iron content have proved suitable as extenders, with talc as the main component because it improves the adhesion to the substrate. The more spherical extenders such as dolomite, chalk and barytes ensure dense packing.

ROSKYDAL 500 A is a formulation of clear and pigmented, wax-free coatings for wood and furniture, high-gloss to matt, with good chemical resistance and very good flow properties and scratch resistance. Also in the formulation of spray and curtain-coating fillers for wood, metal and plastic. Coatings based on ROSKYDAL 500 A cure to formhard, scratch-resistant films. The addition of ROSKYDAL 550 (up to 50 %, calculated on the resin supply form) or E 70 (up to 30 %) improves the flexibility and polishability of the films without reducing the scratch resistance. Fillers and putties can be flexibilized with ROSKYDAL E 65 or E 70. The use of ROSKYDAL E 65 is particularly recommended because of its air-drying properties. As is commonwith unsaturated polyester systems, coatings based on ROSKYDAL 500 A are cured with a cobalt/hydroperoxide combination. The cobalt not only splits the peroxide into free radicals but also promotes surface drying. It thus influences two independent but simultaneous reactions. As the breakdown of the hydroperoxide accelerates at higher temperatures, even without the addition of cobalt, it may be necessary to reduce the amount of cobalt added. Otherwise the surface drying will be much quicker than the polymerization of the film, which may result in surface defects. The cobalt/hydroperoxide ratio must be optimized for the formulation, film thickness, application method and drying conditions selected. The standard addition at room temperature is 0.02 - 0.05 % cobalt metal and 1 – 3 %
