摘要:
The present invention is directed to coating additives useful as non-flatting slip-enhancing agents. The additives are the non cross-linked reaction products of(a) an amine represented by the formula NR 1 R 2 H wherein each R is independently selected from the group consisting of hydrocarbyl groups and hydroxyalkyl groups; or by the formula D-(NGH) y wherein D is a multivalent organic radical having 2 to about 30 carbon atoms; each G independently is hydrogen, a hydrocarbyl group, or hydroxyalkyl group; and y is at least 2; provided that if D is an organic radical containing 2 carbon atoms and y is 2, at least one G must be a hydrocarbyl group of 1 to 30 carbon atoms; and (b) a carboxylic acid ofthe formula B-(COOH) z , or a reactive equivalent thereof, wherein B is a direct link between two COOH groups, a mono- or a multivalent organic radical, and z is 1-5; wherein the resulting product contains at least 2 hydrocarbyl groups each having about 12 to about 30 carbon atoms. The above compositions can enhance the slip properties of a coating composition while retaining the initial gloss.

摘要:
A composition comprising a diesel fuel oil and a nitrogen-containing dispersant wherein the number obtained by multiplying the percent nitrogen of said dispersant by the weight average molecular weight of said dispersant is in the range from about 45,000 to about 100,000, and wherein the composition optionally contains one or more cetane number improvers, stabilizers, corrosion inhibitors and/or flow improvers. These compositions provide exceptional diesel fuel injector cleanliness.

摘要:
A powder coating additive composition containing (a) a non-crosslinked product made by the reaction of an organic alcohol and a carboxylic acid or a reactive equivalent of the carboxylic acid; the product containing at least one ester functionality and at least one hydrocarbyl group of about 10 to about 100 carbon atoms; and (b) a fluoropolymer. The cured coatings exhibit lower coefficient of friction and substantial gloss retention.
