The present invention relates to a method of identifying in a fluid by measuring the amount of optical rotation the fluid causes in a beam of polarized light. The invention further provides for the use of an optional optically active marker in the fluids in order the impact the amount of rotation the fluid will cause. The invention provides a convenient and reliable means for identifying the fluid before, during and/or after the fluid's use.

Optically active functional fluid markers

The present invention relates to using a marker in a functional fluid, which survives the use of the functional fluid in an application, with a reagent solution to identify the functional fluid rapidly either before, during or after the functional fluid's use and which is a suitable method for identifying a functional fluid in the field, and which may employ the use of test wipe, or medium, that contains the reagent solution.

Marker dyes for petroleum products

Dispersion additive system can be applied to fibers or particles, exhibiting improved dispersion, by including in the additive system a sulfonic-acid derived compound such as 2-acrylamido-2-methylpropanesulfonic acid or a salt thereof.

Fiber dispersant-containing systems

Resinous coatings can be applied to glass, exhibiting improved adhesion thereto, by including in the coating composition a sulfonic acid derived compound such as 2-acrylamido-2-methylpropanesulfonic acid or a salt thereof. Alternatively, the glass can be first coated with the sulfonic acid derived compound and thereafter the film-forming resin applied.

Adhesion promoters for glass-containing systems

Waxy hydrocarbyl substituted phenols or phenates are reacted into phenol formaldehyde resins to impart a waxy water resistant nature to binders. A preferred use of the modified phenol formaldehyde resins is as a binder in engineered wood products such as strand board, particle board, medium density fiberboard, plywood and I-beams. Binding the waxy material into the resin may provide a better dispersion of the waxy moieties and prevent migration as has been seen by the simple addition of waxy materials.
