„Manufacturing and distribution of synthetics as well as first-rate consulting service concerning questions related to chemistry and technology.“

It is this business objective that Hans W. Schulz, a businessman in Frankfurt, and Karl Strehle, an engineer in Augsburg, stated when founding the company Poly-Chemie-Ingenieurgesellschaft mbH in 1950. Only one year later the founding fathers successfully got into the market by inventing a new product "Beton-Emulsion" (concrete emulsion). Four years later the PCI product range comprised 54 products already.

The success story of PCI in the field of tile adhesive began in 1959 when the cementitious tile adhesive PCI-FT-Klebemörtel for thin-bed applications was first brought onto the market. In the following years PCI concentrated on the pioneering development of flexible mortars so that a comprehensive system of tile adhesives was realised. Since the market launch of the first pulverised highly flexible special tile adhesive PCI-Flexmörtel in 1981, PCI took on the leadership in the market in the range of tile adhesives.

In the 1970s PCI pursued the development of waterproof tile adhesives and has therefore become an undisputed leader in this technology. At the same time a solvent free PCI-primer on gypsum based substrates was first applied. As a supplementary business the development and production of sealants has been started in the 1960s. In this way brands like PCI Silcoferm, PCI Elritan and PCI Escutan have become synonymous for perfect sealing solutions. In the recent past PCI has distinguished itself by nano and light mortar product development such as PCI Nanolight dust reduced.

Due to the sustainable development and constant improvement of the products the success story of PCI continues. PCI stands for innovation and quality for 60 years.
