Mixed Metal Oxide Nickel Rutile Brown Pigment
Mixed Metal Oxide (MMO) Nickel Rutile Brown is a high-performance inorganic pigment produced by calcining a mixture of TiO2, nickel oxide, and antimony trioxide at high temperature to form a rutile crystal lattice in which Ni and Sb ions replace Ti ions, yielding a clean, warm brown hue. These MMO pigments offer extraordinary stability to heat, light, chemicals, and weathering, making them the preferred choice for demanding exterior, automotive, and high-temperature applications. Chemzip supplies MMO brown in standard and coarse grades.
