The Answer: No. CAB resins are not recommended to be dissolved in toluene (Xylene).
CAB resin can only be used with Ethyl Acetate. It cannot be used with Xylene as it will cause flocculation.

CAB dissolution method: First, dissolve CAB in ethyl acetate. Then, adding CAB solutions to other systems.
Solution to test color and haze: 20% CAB + 80% ethyl acetate.
Then, adjust the ratio of CAB to ethyl acetate based on the specific application requirements.
Tip: To measure color number using the Pt-Co color scale, and to measure haze using a turbidimeter.

So if you donnot know what's CAB resin. You can refer to this explanation.
CAB resin, also called Cellulose Acetate Butyrate. It is a mixed cellulose ester with the features of non-toxic, and bio-degradable. It's equivalent to Eastman Cellulose Acetate Butyrate CAB-381-0.1, CAB-381-0.5, CAB-381-2, CAB 381 20, CAB-551-0.01, CAB-551-0.2, CAB-531-1 and other Codes. Mainly used for various paint, coatings, Lacquers, nail care and other uses.
