We’re working on changes. We invite you at the end of March.

We also conduct comprehensive assessment of compliance with the requirements of standards. We carry out tests according to standards PN (Polish), European (PN-EN), American guides (ASTM), Federal Specifications and German (DIN).

We test raw materials for their evaluation of how they work in the formulas of various coating products.

We study polymer dispersions, fillers, pigments (also pigment pastes), additives (thickeners, dispersants, defoamers, matting agents and many others), coalescents, and others.

We prepare formulas, laboratory samples on a small scale, and then, according to a set research program, we perform tests to compare with other raw materials, find an effective dose or case studies – how a given raw material works in a given recipe.

We study the impact of raw materials on the formation of coatings, we carry out evaluations according to standardized ISO, ASTM, BS, UNI and DIN test methods (see applied research methods in the Testing Service section)

We have a modern research laboratory with calibrated measuring equipment (the laboratory is in the process of accreditation). Each measuring instrument is regularly calibrated and calibrated by specialist calibration laboratories.

We conduct research based on research methods that allow us to assess the actual impact of the raw material on the performance properties of paints and varnishes in liquid form as well as after applying them to the substrate.

We investigate the impact of used raw materials on the degradation of coatings (accelerated weathering), we develop formulas adapted to the realities of the Polish and European market, we provide advice on the transfer of application research results to recipes used in production.

We prepare the results in the form of extensive test reports containing photographs, charts and tables with test results. We can present the results of research at various conferences around the world, including the technology conferences organized by us at the Spektrochem Seminar.

Each time the test program and scope of tests and formulations are agreed with the client.
