New inorganic matting agent for coatings and plastics
In many coating applications and in architectural paints in particular, there is a tendency in the market to prefer matte finishes Vs. glossy surfaces, since they can better mask scratches, craters and impurities.
As well they provide higher cleanability, better surface sensitivity and haptic qualities.
The most common matting agents are silicas, waxes, fillers and polymer beads. Each of them has drawbacks and presents challenges for the formulators.
Hydroxyapatite is a form of calcium phosphate that results to be the main component of teeth and bones.
Kalichem, a Lamberti company specialized in cosmeceuticals, started the technological development of synthetic HAP for the cosmetic and personal care market.
To meet the increasing market demand we have now expanded the manufacturing capacity in Lamberti's Albizzate plant.
At the same time we started to study in our laboratories the application of HAP in industrial fields.
