25 years Evonik Tego Chemie GmbH

For 25 years, the German company Evonik Tego Chemie GmbH has offered its know-how in the field of additives and speciality resins for coatings and printing inks. During this time, the company has become a leading supplier in this field.

In October 1984 Th. Goldschmidt AG established Tego Chemie Service GmbH in Essen. Operations started on 1 January 1985. Even at that time, major products included the silicone resins still used today for heat resistant coatings for saucepans and frying pans, etc. In addition, organomodified siloxanes with their outstanding surface activity rapidly became increasingly important as additives for coatings and printing inks.

From the early years, the company enjoyed continuous growth. Parallel to the activities in Europe, the first regional sales team and a technical service laboratory were set up in the USA. At the end of the eighties, Evonik Tego entered the Asian market which, alongside the USA, has become a mainstay for the company. China, in particular, continues to be a growth area.

Today, the company's products are available from numerous subsidiaries. Evonik Tego is thus able to supply its customers almost everywhere rapidly and provide technical support through the Technical Service Centers. The company also offers tailor-made products. Its portfolio now comprises some 200 products, such as:

• Tego Dispers wetting and dispersing additives promote pigment wetting and stabilisation thus preventing floating and flooding and settling out of pigments.

• Tego Foamex defoamers prevent foaming during production and application of waterborne coatings and printing inks. Existing foam is destroyed and entrapped air is avoided. Tego Foamex defoamers are available as emulsions, solutions and concentrates.

• Tego Airex deaerators prevent formation of air inclusions and pinholes in coatings. This is particularly important in high viscosity or high solids formulations and indispensible when using Airless-/Airmix application methods.

• Tego Wet substrate wetting additives permit uniform wetting of coatings and printing inks even on low energy surfaces. Good wetting is a prerequisite for optimum adhesion. Surface defects such as cratering or poor flow and levelling are avoided.

• Tego Glide & Flow surface additives improve the flow, slip and scratch resistance of coatings. They also prevent cratering and floating of pigments.
