Key types and grades
Non-leafing
With non-leafing aluminium pastes, as shown below, the flake-shaped microparticles distribute uniformly into parallel layers throughout the paint or coating layer. As a result, the colour effect of pigments or other colouring materials present in the paint or coating remains fully visible from the outside.

Design grades
Design-grade aluminium paste, in grades ranging
from Basic Design Grades to the MH, BS, and GX Design
Grade Series, is a product of advanced process technology
by Asahi Kasei that enables the creation of previously
unattainable levels of surface appearance and visual
effects.
As shown in the micrographs below and the Design Grades
map, this technology provides closer control and higher
uniformity of the microparticle size, together with
higher surface smoothness. The result is higher brightness
with smaller particle size – which overturns the
longstanding conventional wisdom that brightness must
vary in proportion to particle size.

coated grades
Resin coated aluminium paste from Asahi Kasei provides
heightened resistance to acids, alkalis, weathering,
voltage, and other demanding environments, and increased
bond strength within the paint or coating layer.
The broad-based technology and expertise of Asahi
Kasei in resin types and processes permit a comprehensive
selection of coating types and thicknesses, to provide
maximum performance for specific application requirements
and conditions.

Leafing
With leafing-type aluminium pastes, the aluminium microparticles tend to float in the paint or other coating during its application to the substrate, and thus form an array of parallel particle layers at or near the surface of the coated layer, as shown below.
This facilitates the achievement of a silver- or chrome-like
visual effect, but care is necessary in its application
and use it may also obscure the visual effects of the
pigment or other components of the paint or coating
layer.
Asahi Kasei provides a range of leafing-type aluminium
paste types and grades, and related expertise in their
use and performance characteristics.
