1. A matting paste composition comprising:
a) thermoplastic non-hydroxy-functional acrylic resin having a weight average molecular weight in the range from about 50,000 to about 100,000 and present in an amount in the range of from about 15 to about 35%, based on the total weight of the matting paste composition; b) hindered amine light stabilizer present in an amount in the range of from about 1.5 to about 8%, based on the total weight of the matting paste composition; c) UV absorber present in an amount in the range of from about 2 to about 8%, based on the total weight of the matting paste composition; d) amorphous, untreated fumed silica, flattener present in an amount in the range of from about 7 to about 13%, based on the total weight of the matting paste composition; e) one or more organic solvents present in an amount in the range of from about 40 to about 60%, based on the total weight of the matting paste composition; and f) from about 2% to about 14% castor oil based on the total weight of the matting paste composition, wherein the castor oil is a triglyceride of 90% ricinoleic acid, having a molecular weight of about 900, a refractive index of 1.4775, and an OH value of 164. |
