A refinish coating composition is provided comprising: a) at least one refinish coating resin; b) at least one solvent; c) at least one pigment; d) optionally, at least one crosslinking agent; e) at least one cellulose mixed ester having a weight average molecular weight (Mw) greater than 10,000 and f) at least one low molecular weight cellulose mixed ester. In addition, processes for coating the refinish coating composition on a substrate are also provided.

A basecoat composition is provided comprising: a) at least one film-forming polymer selected from the group consisting of acrylic polyols and polyester polyols; b) at least one rheological modifier; c) at least one solvent; d) at least one pigment; e) optionally, at least one microgel; f) optionally, at least one crosslinking agent; and g) at least one cellulose mixed ester. A wet-on-wet-on wet process is also provided. The process for coating a substrate comprises: a) applying a primer to said substrate to produce a primed substrate; b) applying a basecoat composition to said primed substrate while said primer is wet to produce a basecoated substrate; and c) applying a clearcoat composition to said basecoated substrate while said basecoat composition is wet and optionally said primer is wet to produce a coated substrate. Coated articles are also provided.
摘要:
Disclosed is an improved process for the preparation of tocotrienol/tocopherol blend concentrates from vegetable oil distillates which are enriched in tocotrienols. Tocotrienol/tocopherol blend concentrates are obtained containing 20-80% tocotrienols/tocopherols by weight, with an overall recovery of tocotrienols/tocopherols of 72% to 97%. The process is comprised first of an esterification reaction where the more volatile alcohols are converted to their less volatile fatty acid esters, followed by a series of distillation steps where components boiling higher and lower than the tocotrienols/tocopherols are separated from tocotrienols/tocopherols and other like boiling substances. Advantages of the process are that tocotrienol/tocopherol blend concentrates are produced efficiently and economically in a minimum number of steps without the use of solvents and with a relatively small capital investment.
