Solvent action in glycol ethers comes from the C O C ether linkage. In ketones, the double bond oxvgen does the work. Shell Chemical's Pent-Oxone is the only commercially available solvent with both these functional groups. are t a k e n after o n e h o u r o n a 5 0 / 5 0 s o l v e n t / t o l u e n e m i x t u r e w i t h t h e indicated Vinylite** resin: 10% VYNS-3
