摘要： Provided are an amino resin composition, a varnish, a coating layer, and a product. The amino resin composition comprises a repeating unit represented by the following Formula (I): A 13C-NMR spectrum of the amino resin composition has a first characteristic peak at 159 ppm to 161 ppm and a second characteristic peak at 70 ppm to 80 ppm. Based on the integral value of the first characteristic peak as 1, the integral value of the second characteristic peak is in the range from 0.01 to 0.25. Adopting the amino resin composition can accelerate the drying of the varnish and ensure the coating layer and the product have high hardness, high gloss and excellent color stability.

摘要： An epoxy resin composition comprising a blend of at least (i) at least one epoxy group containing a polycyclic group, and (ii) at least one epoxy group that is different from the epoxy resin in component (i). As exemplary of component (i) is an epoxidized tricyclo decanedimethanol. A renewable epoxy of component (ii) is cardanol epoxy, derived from cashew nut shell oil (CNSL). Optionally, a component (iii) which is any other epoxy from that of (i) and (ii) can be included, such as Bisphenol-A/F diglycidal ether. The blend is characterized by low viscosity, making it amenable to airless spray application, high solids content and excellent solvent resistance and abrasion resistance.

摘要： Provided is a melamine-formaldehyde resin composition. In a first aspect, the melamine-formaldehyde resin composition has at least one melamine oligomer with a mass-to-charge ratio (m/z) ranging from 393 to 692. Based on the total area of all chromatographic peaks in the melamine-formaldehyde resin composition, the sum of the areas of the chromatographic peaks with m/z of 393 to 692 ranges from 2% to 20%. In a second aspect, the melamine-formaldehyde resin composition comprises 2,4,6-tri[bis(methoxymethyl)amino]-1,3,5-triazine, and the area thereof ranges from 15% to 33% based on the total area of all chromatographic peaks in the melamine-formaldehyde resin composition. The melamine-formaldehyde resin composition of the present invention has superior freeze resistance and extended low-temperature storage life.

摘要： This disclosure relates to reactive epoxy compounds that have high water solubility. The reactive epoxy compounds are obtained by mixing an epoxy resin having at least two epoxy groups per molecule with a carboxyl group-containing compound obtained by reacting a polyetheramine comprising a primary amine and an acid anhydride derived from a polyvalent carboxylic acid. This disclosure also relates to waterborne epoxy resin composition comprising core-shell type epoxy resin particles dispersed in a solvent, wherein the particles are formed by an epoxy resin encapsulated in the reactive epoxy compounds of the present invention. The waterborne epoxy resin composition is low in volatile organic compounds (“VOC”).
