Problems solved by technology

One of the key unmet needs of existing water-based wipe stains is the short working time (eg, about 15-20 minutes), which limits their application to large surfaces such as large furniture
Additionally, the dry film clarity of wipe stains is critical to the presentation of the desired stain color and has a limited impact on the film clarity of the overall coating system

Abstract

An aqueous composition having an extended working time and providing a film with high clarity, the aqueous composition comprising: (a) an oligomer having a number average molecular weight of 250 to 30,000 g / mol comprising 5 to 20 wt%, based on the weight of the oligomer, of structural units of an acid monomer, a salt thereof, or a mixture thereof; (b) a hydroxypropyl methyl cellulose having a degree of methoxy substitution of 1.5 or more; and (c) a diol containing 2 to 6 carbon atoms and having a boiling point of 110 to 280 DEG C.

Description

technical field [0001] The present invention relates to aqueous compositions and methods for their preparation. Background technique [0002] American furniture is a very popular segment of furniture that uses a solvent based coating system with over 15-20 coats to give the newly made wood plank the final look old. In such coating systems, wipe stains play a key role in staining wood and giving furniture a classic look. Conventional wipe stains typically contain 10-15 wt % oil, 30 wt % colorant, and 55 to 60 wt % solvent, based on the total weight of the wipe stain. Water-based (also known as water-based) coating compositions are increasingly becoming more important than solvent-based coating compositions due to fewer environmental concerns. One of the key unmet needs of existing water-based wipe stains is short working time (eg, about 15-20 minutes), which limits their application to large surfaces such as large furniture. In addition, the dry film clarity of the wipe st...
