RAIN is a global leader and innovator in the production of resins and modifiers, aromatic chemicals, superplasticizers and other specialty chemical products. RÜTGERS, a wholly-owned subsidiary of RAIN, is a market leader in Europe for the manufacture of chemicals produced from coal tar. RAIN operates chemicals production facilities in Germany, Canada and the Netherlands.

RAIN produces 0.3 million tons of specialty chemicals per annum, which account for over 18% of RAIN’s consolidated turnover. Its products have applications ranging from rubber tires to printing inks, and from concrete to pharmaceutical products.

RAIN produces chemicals in two parallel production processes:

  • Downstream processing and refining of primary coal tar distillates
  • Petroleum derivatives, such as C9 and C10, which serve as raw materials for the production of resins and modifiers, aromatic chemicals and superplasticizers.

RAIN’s chemicals business is classified into three sub-categories.

Resins and modifiers

RAIN manufactures hydrocarbon resins based on coal tar distillates produced during the downstream refining of carboindene. Modifiers are produced from the downstream refining of naphthalene and from other inputs procured externally.

Coal tar-based resins are used primarily for applications in coatings, rubber tires while petrochemical-based resins are used primarily for applications in adhesives and printing inks. RAIN produces surface modifiers that are used for coating industrial floors, cable joints and water-based adhesives.

Aromatic chemicals

RAIN manufactures aromatic chemicals from the downstream refining of carbolic oil and from coal tar distillation. Carboindene is produced from further downstream refining of carbolic oil. The aromatic chemical products are used as precursors for several end-user products. RAIN manufactures two main categories of aromatic chemical products: phenolics and carbozole products.

  • Phenolics are used for applications in leather treatment, electric wire enamels and also pharmaceuticals.
  • Carbozole is an important constituent for Violet PV23, a high-performance pigment used in textiles, printing inks and plastics.


RAIN produces specialty polymers called superplasticizers from the downstream refining, polymerization and purification of naphthalene oil and naphthalene. Superplasticizers are used as in-process aids in the manufacture of concrete and gypsum wall boards, and have widespread use for a variety of industrial and agricultural applications.

RAIN also produces a wide range of differentiated naphthalene and melamine superplasticizers in liquid and powder form, as well as carboxylate dispersants in liquid form.

Innovating the future

The research and development division of RAIN constantly focuses on optimizing product mix and conversion costs. RAIN’s customized production and strong R&D focus helps it to create products to match customer requirements and specifications.

A dedicated product development and applications team works closely with clients to tailor the quality and grade of resins and modifiers to meet specific application needs. RAIN has successfully launched several innovative products developed by its in-house product development and application division such as:

  • Coal tar-based resins for rubber tire applications in electric cars.
  • Colorless water-white resins for use in color-sensitive adhesive applications such as tape and book bindings.
  • A new generation of eco-friendly resins, with water-miscibility, to be used in waterborne coatings and adhesive formulations with reduced volatile organic emissions.
