HEUCO®FIT LR

The HEUCO®FIT LR preparations have been developed for direct replacement of chrome yellow and molybdate red pigments. In selecting suitable organic and inorganic pigments, the focus was on a good balance of coloristic properties and the hiding power in the near-full shade color range. This is particularly interesting in the area of industrial paints, since good substrate hiding by a one-coat application of the paint with low layer thickness is necessary. The light fastness and weather stability of lead chromates depend on the types used and their surface stabilization.

The majority of lead chromates used on the market are standard types. Complex Inorganic Color Pigments (CICP) such as P.Y. 53 and P.Br. 24 exhibit excellent properties. Similar to lead chromates, organic pigments vary greatly in weather stability. In selecting appropriate organic pigments and combining them with yellow/orange CICPs, most of the weather stability requirements can be resolved. Cost-designed pigment preparations can replace standard lead chromates. Pigment preparations formulated with weather-fast organic and inorganic pigments are not inferior to stabilized lead chromates and can even outperform standard products.
