Description Of Urea Resin Powder
Urea-formaldehyde resin is also known as urea formaldehyde resin. English abbreviation UF, is urea and formaldehyde in the catalyst (alkaline or acidic catalyst) under the action of condensation into the initial urea formaldehyde resin, and then under the action of curing agent or additives, the formation of insoluble, non-melting thermosetting resin at the end. It is translucent, resistant to weak acid and alkali, good insulation performance, excellent wear resistance, cheap price, very suitable for tableware, tableware made, light and not easily broken. The molecular structure of urea-formaldehyde resin contains polar oxygen atoms, so it has good adhesion to the surface. Can be used for primer, intermediate layer coating, in order to improve the adhesion between the top paint, in order to reduce brittleness, improve toughness can add polyvinyl alcohol, polyvinyl formaldehyde solution, polyvinyl acetate emulsion, Vae solution, and so on, but also can improve the initial viscosity and aging resistance.
With it to make tableware according to the national process production standards production is safe, with strong heat resistance, fall resistance, safety, easy to clean and other characteristics, the product is not eroded by oil, gasoline, organic solvents, not easy to stain, good water resistance, good washing resistance, can be used for any cleaning agent on the market washing,
At the same time, its weight is light, with a specific gravity of 1.6, and its weight sense is moderate. The product has good heat resistance and fire resistance. Clean in dishwasher and store in disinfectant cabinet.
