Engineered Coated Minerals Close the Opacity Gap for Coatings
Suppliers coat and mill calcium carbonate, silica, and phosphate to raise brightness and coverage, closing much of the 20% to 40% opacity gap to titanium dioxide in sweets, icings, and dairy alternatives. Engineered coated mineral whitening systems grow about 12.2% a year and sell at premiums of 30% to 100% over standard calcium carbonate. The trend needs particle engineering and rewards suppliers with proven opacity data. Supply contracts decide renewal. Delivery reliability decides supplier rankings. Margins follow sourcing discipline. Buyers review suppliers every season. Batch records protect future sales. Cost control separates leaders from followers.
