The present invention discloses a ketone-aldehyde modified resin and the preparation process thereof. The ketone-aldehyde modified resin comprises a ketone-aldehyde modified unsaturated polyester, a ketone-aldehyde modified unsaturated alkyd or the combination thereof, and wherein the said resin has ketone-aldehyde moieties. The process of the said resin comprises the steps of: reacting unsaturated polyester-forming and/or unsaturated alkyd resin-forming monomer components with a ketone-aldehyde resin. The present invention also discloses a coating composition comprising the said resin as well as a coated article. The ketone-aldehyde modified resin and the coating composition achieve significantly improved fast drying effect, while other properties are not observably impaired or even improved.
WATER-BASED COATING COMPOSITIONS THAT RESIST DIRT PICKUP
Water-based compositions containing a low VOC coalescent, a latex or water-dispersible polymer are described.
Waterborne heat-insulation coating and composition thereof
A waterborne heat-insulation coating uses a silicon dioxide dispersion with silicon dioxide evenly dispersed in resin through a sol-gel method as a heat-insulation agent; since the silicon dioxide dispersion has great fineness and large specific surface area of between 30.1 and 100 m.sup.2/g, the waterborne heat-insulation coating when applied to building surfaces forms a coating layer that features a packed structure, a smooth surface, and a high surface reflectivity of 85% or more; resulted in that the coating layer can effectively block infrared rays and provide excellent thermal shielding effects, stain resistance, and durability.
Additives for coating compositions and related methods
Disclosed are curable coating compositions, and methods of cathodic corrosion protection using the compositions. For example, a curable coating composition comprising a mixed salt of magnesium thiodialkanoate, and a method for applying the coating composition, which when applied onto a steel or other ferrous substrate provides an anticorrosive coating, effective for improving resistance to cathodic disbondment.
