Applications
1.High-Grade PU and PE Paints for Wood Paints
A key additive for high-quality polyurethane (PU) and polyethylene (PE) wood paints is zinc stearate. It helps with flow, gives a smooth finish, and makes it easier to apply even coatings on wood surfaces.
2.Upscale Piano Coatings
Zinc stearate improves the quality of the finish and makes it resistant to damage, while also making it shiny, all of which benefits high-end piano coatings. Provided excellent dispersion and lubricating properties guarantee smooth application and reliable surface protection.
3.NC Paints and High-Grade Inks
NC paints and high-quality inks contain zinc stearate as an ingredient. Zinc stearate helps with good mixing, better stability, and improved performance. It delivers brilliant colors and an even high-quality finish.
4.Pencil Lead Manufacturing
Zinc stearate is an important part of pencil lead. It works as a dispersant and a lubricant. This helps mix materials easily and improves product performance. It increases the quality of the lead making writing smooth and the lead long-lasting.
Storage and Handling
Storage and transport under a shady, cool, and ventilated environment; Avoid acid, alkal, and corrosive substances. Keep it away from the humidity, hotness, fire, and corrosion.
