 | Wollastonite is growing in popularity as a mineral reinforcement for paints and coatings. Due to its unique chemistry and structure, wollastonite allows formulators to improve the cohesive strength of their coatings to obtain better corrosion and barrier properties, extend in-can stability and improve thermal stability at high temperatures. Specialty chemical modifications added to the wollastonite substrates further enhance adhesion and mechanical properties at cost savings compared to traditional corrosion pigments. |
