Rapid-curing baking paint, water-borne wood coatings, convertible varnish, paper coatings.


YDN516 is a methylated urea-formaldehyde resin that can be used as a bridging agent for hydroxyl-functional polymers in water-based or organic solvents.

YDN516 does not require solvents, can cure quickly at low temperatures, has good compatibility, excellent stability, and low cost.

When used for rapid curing of YDN516 resin/alcohol-acid resin baking paint, no acid catalyst is required, and the curing speed of the paint is almost twice as fast as that of traditional butylated urea-formaldehyde resin when drying for a short time or not drying at all.

YDN516 is compatible with most resins, including alcohol-acid, polyester, acrylic, and epoxy.

Our company was specialized in producing melamine resin since establishment. On top of our mature melamine resin technology, we have expanded our technology and production to the melamine foam industry. We have established our own laboratory for continuous research and development of new melamine resin and melamine foam materials. Through the years we have obtained 13 invention patents and 13 utility model patents for melamine foam plastic material and its production technology. We are the only professional manufacturer domestically and internationally that can produce a diverse series of melamine foam plastic products, including the semi-rigid melamine foam, which has applied for patents in the United States and Japan and is under substantive examination.

Besides the superior capability of water absorption, our melamine foam also has excellent sound and heat insulation capabilities as well. The material has been used not only in household cleaning, but much more in industrial fields, e.g. power battery insulation material, aerospace ultra-light materials, flame-retardant construction materials, acoustic materials, etc. With a complete and established quality management system, our company had been appraised by our customers in our high quality products and competitive pricing.
