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-36 is a binder for highly filled, coarse and fine knifing fillers for use on metal, wood and mineral substrates. Due to the high reactivity of ROSKYDAL K 36, fillers based on this product quickly cure to sandability, especially with sandingmachines. The hardness of ROSKYDAL K 36 is equivalent to that of a 1 : 1 combination of the hard ROSKYDAL K 14 M and the flexible ROSKYDAL K 60. ROSKYDAL K 36 is ideal for use as the sole binder for car body fillers. It can be made harder by the addition of ROSKYDAL K 14 M and more flexible by combination with ROSKYDAL K 60. The low viscosity of the resin promotes the wetting of the extenders, thus reducing the formulation time of fillers.

ROSKYDAL K 60 is a binder for highly filled, coarse and fine knifing fillers with long potlife. ROSKYDAL K 60 enables formulation of fillers with long potlife of 30-45 min. using the standard hardener Di-Benzoylperoxide. ROSKYDAL K 60 is also suitable for fillers with overbaking resistance at temperatures up to 170°C. Fillers based on ROSKYDAL K 60 cure fully when applied in both thin and thick coats.They can be made harder by the addition of e.g. ROSKYDAL K 14 M or ROSKYDAL K 36. Formulation Talc, dolomite/calcite and powdered barytes with low iron content have proven suitable as extenders, with talc as the main component because it improves the adhesion to the substrate. Only coarse and blended talcs should be used to formulate fillers with overbaking resistance up to 170°C.
