ROSKYDAL K 65 is a binder for highly filled, coarse and fine knifing fillers for use on metal, wood and mineral substrates. Fillers based on ROSKYDAL K 65 cure fully when applied in both thin and thick coats. They can be made harder by the addition of, for example, ROSKYDAL K 14 M or ROSKYDAL K 36. Formulation Combinations of talc, dolomite/calcite and baryteswith lowiron content have proved suitable as extenders, with talc as the main component because it improves the adhesion to the substrate.

ROSKYDAL XP 2072 is especially suitable for conventional- or UV-curing (transparent or pigmented) topcoats and pigmented sealers for wood and furniture. properties for applications by spraying or curtain in UV- or conventionalcuringsystems. ROSKYDAL XP 2072 is usually used as the sole binder. If made necessary by the application (high amount) and compatibility exists, it can be flexibilized with other ROSKYDAL grades, e.g. ROSKYDAL 550 or E 70.

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 %
