COATING FORMULATORS: How Shell's new PENToXONE* and PENToXOL* solvents can save money, improve formulations and eliminate the need for specialty high boilers HELL'S P E N T O X O N E and PENT
S
oXOL are unusually active high boiling solvents. Together, they constitute a vir tually complete high boiler inven tory. Below is solubility data for 30 im portant resins in PENToXONE and PENToXOL solvents. W i t h acrylics, nitrocellulose and alkyds, these n e w Shell solvents can
improve your formulations. W i t h vinyls, PENToXONE lowers solvent cost and improves odor. W i t h thermosetting acrylics, efoxies and cellulose acetate butyrate, both PENToXONE and PENT oXOL give excellent film properties. I n urethane systems, PENT oXONE solvent has low isocyanate reactivity, eliminates need for pre m i u m priced upgraded solvents.
In -polyvinyl hutyral lacquers, PENToXOL can lower solvent cost by 11 φ per gallon and almost double water resistance.

Remarkable activity of Shell's PENToXONE high boiling solvent comes from this unique keto-ether structure. The COC of ethers and the double bond Ο of ketones com bine for double action solvency. Shell's PENToXOL solvent is a very closely related glycol ether. Both these solvents are true high boilers. PENToXONE'S total evapo r a t i o n t i m e is 2 4 5 0 s e c o n d s . PENToXOL'S is 3375 seconds. *Shell Trade Marl·.
