Drying Oil Alkyd
SOLVAR™ A is a fast, hard drying, 100% non-volatile synthetic, low viscosity alkyd. This alkyd may be used as a diluent to reduce tack and increase flow while improving dry and rub resistance. Drying speed is equal to most #3 litho viscosity alkyds and final hardness is equal to most #7 litho alkyds. Pigment wetting is very good. As little as 2% of SOLVAR™ A in a heatset or sheetfed ink will give more flow and transfer than any other additive vehicle.
Formulating with SOLVAR™ A in the 5 to 15% range in lithographic or letterpress inks can develop higher gloss, better flow, and greater color strength and transfer. Inks that form a brittle film can be toughened with SOLVAR™ A without sacrificing set or dry time, and gloss will be improved, if tack is maintained. Oil inks that tend to lose transfer at high press speeds can be dramatically improved with the addition of SOLVAR™ A. SOLVAR™ A builds the rub resistance that is essential to quality carton printing.
