An article in the Feb. 1 issue incorrectly implied that a licensing agreement between BASF and Lubrizol covers all of the Emgard and Plurasafe lines. Lubrizol will produce and distribute only Emgard 2946; Emgard CL 4046 and 4068; Emgard EP WG 680; Emgard HT CL 5220 and 5320; Plurasafe CL 6032, 6046 and 6068; Plurasafe P 44; and Plurasafe WGF 200 E.
