keim additec surface GmbH –  producer and developer of water based ULTRALUBE® wax additives as the benchmark in various coating applications

In a globalized environment keim additec surface GmbH founded 1988 and located in Kirchberg (Hunsruck) in Germany has specialized in the production and development of water based ULTRALUBE® wax additives and counts today to the market leaders in multiple coating applications.

The use of aqueous ULTRALUBE® wax additives ranges from applications in e.g. printing inks, OPV's, lacquers and paints by adhesives and care products up to specialized applications e.g. in digital printing, paper or glass fibre coatings in order to generate or modify desired surface properties of the resulting coating systems. Besides a nearly 30 years of experience especially the close cooperation with partner companies in the field of solid waxes (euroceras and ceronas) as well as non-wax based coating additives (silcona) is a solid basis for our chemists, engineers and application technicians to develop the product portfolio continiously and customized further. Additionally synergistic effects can be utilized thereof. Partner companies euroceras and ceronas also open the possibility for access to customized raw materials besides the general advantage of being backward-integrated in the most important wax types.

The modern and partly unique production units exhibit a capacity of around 40.000 t /a of aqueous wax additives.
