MACRYNAL SM 513/60LG is an excellent mechanical properties and chemical resistance, high gloss. Fast drying two pack systems, in paricular for primer surfacers for car repairs and for general industrial applications. In combination with aliphatic polyisocyanates Macrynal SM 513/60LG is recommended for at ambient temperature drying or forced drying two pack systems. The principal application field is automotive refinishing and high-grade industrial paints. Due to its rapid initial drying Macrynal SM 513 is especially useful for the formulation of primer surfacers. Automotive refinishing clearcoats based on Macrynal SM 513 must be stabilized with light stabilizers.

SETALUX 1202 SS-70 is a high solids content with airless or airmix spray applications. In combination with aliphatic poly-isocyanates: fast drying, good hardness, good outdoor durability,good gloss and build, good solvent and chemical resistance and good mechanical properties. It is used as industrial topcoats with good solvent and chemical resistance.

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 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).
