摘要:
Dioxolane compound film-forming agents are formulated into surface coating compositions such as paints and varnishes, in particular industrial, graphic and architectural paints, and serve as coalescence agents and/or drying retardants.

Low levels of surface-active, aliphatic C.sub.16 or greater hydrocarbon-type compounds are used to reduce the rate of evaporation of water from waterborne polymer products such as latex coatings. This increases the wet-edge or open time of the freshly applied coating, improves integrity and adhesion of the dried coating, and reduces skin formation in containers and on application equipment.
摘要:
Coating materials containing aliphatic .alpha.-hydroxyketones of the general formula ##STR1## where R and R.sup.1 are each hydrogen or a hydrocarbon radical of 1 to 4 carbon atoms, as antiskimming agents. These .alpha.-hydroxyketones are particularly useful in paints and finishes based on oxidatively drying alkyd resins.
摘要:
The present invention relates to coating compositions containing oxidatively drying binders and anti-skinning agents corresponding to formula (Ia) or (Ib) ##STR1## wherein Y.sub.1 and Y.sub.2 are the same or different and represent hydrogen, chlorine or fluorine,X.sup..sym. represents a group corresponding to formula I ##STR2## and R.sub.1, R.sub.2, R.sub.3, R.sub.4 and R.sub.5 are the same or different and represent hydrogen, a C.sub.1 -C.sub.10 linear or branched alkyl group that may contain one or more hydroxy groups, an aryl group or a C.sub.5 -C.sub.7 cycloalkyl group.The present invention also relates to anti-skinning agent mixtures containing these anti-skinning agents.
摘要:
Disclosed is a method to inhibit the formation of a paint-product skin on the interior surface of the lid of a closed upright vessel housing a paint composition wherein a portion of said composition is volatile. The method comprises delivering said paint composition to an upright, open vessel closeable at its top with a lid; delivering a sufficient quantity of a barrier material to the open vessel to provide a covering layer of the barrier material for the top of the paint composition; and closing the open vessel at its top with a lid. The barrier material is characterized as (1) less dense than the paint composition; (2) containing a volatile portion whose volatility is at least substantially equivalent to the volatility of the volatile portion of the paint composition; and (3) sufficiently compatible with the paint composition to become a mixed non-detrimental component thereof upon adequate mixing therewith.
