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.

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 %
