MACRYNAL VSM 2155/60EPAC, in combination with aliphatic polyisocyanates, pre-eminently with Desmodur N 75 (Covestro), produces two-pack clearcoats and pigmented topcoats with excellent chemical resistance for the industrial acquer sector. MACRYNAL VSM 2155/60EPAC is especially suited for coatings on aeroplanes or military vehicles.

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.

MACRYNAL SM 565/70BAC is used for air-drying and forced drying high-solids two pack coatings with high gloss, outstanding mechanical properties, excellent chemical resistance and outdoor stability. In combination with aliphatic polyisocyanates, pre-eminently with Desmodur N 3390, Macrynal SM 565 is used for air-drying and forced drying high-solids two pack coatings. The principal application area is high quality automotive refinishes and high-performance industrial coatings.

MACRYNAL SM 2855/70BAC is a high solid binder for the formulation of fast drying, highly crosslinked two-pack polyurethane coatings providing outstanding properties in terms of chemical and solvent resistance. In combination with low viscous, aliphatic polyisocyanates Macrynal SM 2855 provides air-drying and forced drying high-solids two-pack top- and clearcoats characterized by a low content of volatile organic compounds (VOC) together with a very fast hardness increase upon curing. When fully crosslinked these coatings match highest requirements in terms of chemical and solvent resistance as well as low VOC emissions (< 420 g/l) making aircraft coatings, military vehicle coatings, etc. the main areas of application, the use in car repair clearcoats, mainly as combinatorial resin, is also possible. For use in more cost-efficient industrial topcoats it is recommended to considerably undercrosslink (70 - 80 % theoretical degree of crosslinkage). Such high-solids coatings provide excellent early hardness combined with high end hardness also at lower curing temperatures (e.g. 5 - 10 °C in field applications), as well as good outdoor resistance.
