ACRYLIC FORMULATORS: Shell Chemical's new PENToXONE* and PENToXOL* high boiling solvents give you flexibility never before possible in high-low solvent systems for acrylic lacquers PENToXONE solvent is Shell's remarkable new keto-ether. PENToXOL solvent is a glycol ether. Both are true high boilers which impart gloss to acrylic lacquers. They virtually triple the number of effective acrylic solvents you can choose from in the high boiling range. For details, see below- and send for Shell's new technical bulletins. AS YOU KNOW, high-low solvent sysJr\ terns for acrylic lacquers place a heavy burden on high boiling solvents. For years, ethylene glycol monoethyl ether acetate has carried most of this burden alone. Now, Shell Chemical has developed two new high boilers which lighten this load and give you a flexibility which has hitherto been missing in acrylic lacquer formulation.
Solution viscosity data Both PENToXONE and PENToXOL solvents are highly active. Here is how they compare with EGMEE acetate in solution viscosity for three widely used Rohm & Haas acrylic resins : A-21 B-44 B-66

All three resins were reduced to 15 per cent by weight as follows: A-21 with 45 parts toluene, 5 parts butyl alcohol and 50 parts indicated solvent; B-44 with 26.5 parts toluene and 73.5 parts solvent; B-66 with solvent alone.
Unrubbed acrylic lacquer with Shell's PENToXONE solvent, left, gives greater gloss reading (77) than identical formulation with equivalent amount of EGMEE acetate ( 7 2 ) . PENToXOL solvent gives similar high gloss levels in acrylic lacquers.
Gives high gloss levels Acrylic lacquers with PENToXONE or PENToXOL in the solvent system give you higher gloss levels than you can obtain from any other high boiler at equal concentration. These ojoss levels remain high under a wide variety of application conditions, such as force dry time and temperature, spray room temperature, topcoat thickness, primer smoothness, pigmentation and operator efficiency. This feature readily translates into lower manpower and elapsed-time costs in rubbing operations.
