Geotech is a dynamic and innovative company with a clear focus on the development, production and distribution of special effect pigments. Quality control, product development, formulating support and technical training create high added value for customers and partners since more than 25 years now.
With the ambition to become the third pillar of the company Geotech launched a new range of special effect pigments for plastics and coatings. The new group of metallic pigments fits perfectly into the portfolio of special effect pigments (pearlescent pigments and glitter).
The new Metalloy® effect pigments are aluminium based pigments offering metallic effects. Geotech offers a complete range of 35 new products for coatings, plastics and inks.
The metallic effect is based on the reflection of light on the surface of the pigment. This reflection is overlayed by the light scattered at the edges of the flake and by the micro-roughness of the pigment surface. The metallic effect is the sum of the reflection and the scattering of light. The higher the ratio of reflected light, the more intense the metallic effect.
Leafing and non leafing
-
The range of products can be divided into non leafing and leafing products.
Leafing aluminium flakes float and align at, or near the surface of the film, creating an opaque coating with silver or chrome effect. Leafing pigments form an excellent barrier to prevent penetration of corrosive substances.
Non leafing aluminium flakes are evenly distributed throughout the coating film. This structure allows the light to be reflected by the flakes and emitted out through the coating film, enhancing whiteness, lightness, or vividness of films.
