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 VSM 2702/58XSNA is used in combination with aliphatic polyisocyanates, e.g. Demodur N 75 or Desmodur N 3390 for high quality two-component industrial coatings. To be emphasized is the excellent adhesion, even to non iron metals.

MACRYNAL VSM 2570/70BAC is a high solids content at application viscosity- Good drying speed. Good adhesion to metals. Very Good mechanical properties, Good gloss and Good outdoor durability. Macrynal VSM 2570 is a hydroxy functional acrylic resin cross-linkable with aliphatic polyisocyanates to formulate air drying and forced drying 2-pack high solids coating systems. In pigmented topcoats (pigment/binder = 1 : 1) a solids content of 65 % at application viscosity of 55 s (efflux time DIN EN ISO 2431, 4 mm, 23 °C) can be achieved. To ensure that optimal properties are obtained it is necessary to have complete crosslinking. For stoichiometric (equivalent) crosslinking (NCO : OH = 1 : 1) approx. 100 parts per weight Macrynal VSM 2570 (f.o.d.) require approx. 21 parts per weight Desmodur N 3390 (Covestro). in combination with amines like diethyl amino ethanol (approx. 0.2 %, based on solid resin). Potlife is thereby reduced, however. Dilution Suitable diluents are butyl acetate, methyl isobutyl ketone, 2-methoxypropyl acetate or aromatic solvents like solvent naphtha 150/180. Anhydrous solvents as well as solvents free of hydroxy functional groups should be used in the presence of isocyanates. Pigments Inert pigments and extenders are suited for pigmentation. Pigments with basic surface treatment can act as additional catalyst and shorten the potlife even more.

Additives To improve levelling ADDITOL VXL 4930 is recommended. ADDITOL VXL 6212 has proved to be an effective wetting agent.

SETALUX 1226 SS-60 is an extremely fast curing, hydroxy-functional acrylic polyol for two component vehicle refinishapplications. Paint develops hardness and chemical resistance very fast. In addition, it provides excellent application properties, excellent gloss and DOI. Key features: Very fast cure. Excellent early hardness development. Excellent appearance and gloss. It is used as clearcoats for vehicle refinish and transportation. Modifier resin for two component polyurethane coatings to improve curing speed.
