Leafing Alpaste®

Outline

In this type of paste, surface tension causes the aluminium flakes to float to the surface of the coating and arrange in parallel. This makes is possible to achieve a gloss similar to that of chrome plating. The leafing effect also means that the coated film has high reflectance and an excellent rust prevention effect. We have a wide variety of types available with different aluminium flake diameters and base 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.
