ROSKYDAL XP 2072

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 300/1

ROSKYDAL 300/1 is a formulation of clear and pigmented UV-curing top coats with very good flow properties for application by spraying and curtain coating. After the addition of photo-initiators, ROSKYDAL 300/1 can be cured under UV lamps. When using high-pressure mercury vapour lamps with a capacity of 80 - 120 W/cm lamp length, standard commercial initiators can be used. However, their suitability for the intended application should be tested, especially with respect to storage stability, reactivity and yellowing. The use of 2.5 % Irgacure® 17001 or Irgacure 6511 is recommended for clear coats (max. application rate: 250 g/cm2). In the case of top coats, Baysilone® Paint Additive PL2 should be used to promote the flow properties. The addition of 2 % of a 1 % solution in toluene is recommended. Pigmented coatings should be formulated using 2 % Lucirin® TPO1 or other suitable photoinitiators. All the quantities given are calculated on the resin supply form. Clear coats may contain soluble dyestuffs and highly disperse silicas. Primers are formulated using highly disperse silicas and quartz powder. Soluble dyestuffsmay also be added. The addition of 5 - 10 % Desmodur® L or Desmodur N improves the adhesion. However, such combinations have a limited pot life (approx. 24 hours with a 5 % addition of Desmodur L).
ROSKYDAL K 60

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.
ROSKYDAL K 65

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.
