Leafing ALPASTE®
Outline
Surface tension causes the aluminium flakes to float to the surface of the coating and arrange in parallel and helps achieve high metallic sheen. The leafing effect gives high reflectance and excellent rust prevention. Variety of leafing pastes are available based on different particle size distributions and solvents.
Structure
Standard Series
This product series uses stearic acid as a grinding aid and the particles rise to the surface of the coating film due to surface tension. Medium-grain particles are often used in anti-corrosive and heat resistant paints, while small-grain particles are frequently used for offset ink and other applications.
High Gloss Series
This leafing type has high gloss due to careful pulverization. It has smooth particles with uniform particle sizes. The high gloss properties are put to use in applications such as automobile reflectors.
