  • Tools for technical marketing

    Tools for technical marketing

    In our Technical Center, we cooperate with producers of raw materials for water-borne paints based on test programs tailored individually to client expectations.

    Based on case studies carried out in our laboratory, we develop test reports that are extremely helpful for the TS&D, technical marketing and R&D departments of raw material producers to develop technical materials that accelerate the implementation of raw materials on the global coatings market.

    Our laboratory specializes in formulating recipes and testing raw materials for water-based architectural, wood and metal paints, in which we test the effectiveness and performance of raw materials in formulations with different pigment volume concentration, based on various binders, additives, fillers, etc., intended for the markets of USA, Canada, North America, Europe and Asia-Pacific (based on locally available raw materials for each region).

     

    We specialize in developing:
    – start point formulations
    – case studies, e.g. comparison of raw materials
    – ladder doses, i.e. for additives performance

     

    While developing the above, we prepare paints based on raw materials from our raw material library and test samples sent by the customer, we perform tests of liquid paints, their drying processes and dried coatings. We perform tests in accordance with the standards of ASTM, ISO, Federal Test Methods, AATCC, MPI, etc.

     

    At the end of the projects, we present the client with extensive reports, photos from tests, coatings after tests and give the opportunity to visit our laboratory to summarize the test results or we summarize the project by meeting on-line.
  • Support for sustainable raw materials

    Support for sustainable raw materials

    We are focused on conducting case studies for new raw materials, in particular those based on renewable resources that meet strict ecological criteria, sustainability policy, circular economy and reduce the carbon footprint. In our laboratory, we compare conventional raw materials with bio raw materials in formulations dedicated to applications as architectural paints and varnishes, as well as wood & metal coatings.

     

    We prepare technical reports in which we compare the efficiency of conventional (petroleum-based) raw materials with raw materials from renewable resources, testing their stability in formulations dedicated to various markets, comparing the impact of individual raw materials and their doses on the properties of liquid paints and coatings.

     

    Thanks to our technical reports with extensive test results prepared for producers of sustainable raw materials, we help formulators in the R&D departments of paint manufacturers to decide on the use of a sample in tests, and thanks to the provided comparative results, we allow us to reduce the time of testing at the paint manufacturer and draw faster conclusions as to the effectiveness and validity the use of a new raw material in the production of paints.

The chambers are equipped with a precise radiation monitoring system, rainfall and condensation. For all tests, there is a water control system used for testing with all water parameters determined during testing in accordance with ASTM.

     

    Tests in laboratory chambers are carried out in accordance with the standards as in the table below, however, taking into account the guidelines included additionally in the standards:

    ·         ASTM G154 – for all exposure tests in fluorescent UV chamber

    ·         ASTM G155 – for all exposure tests in xenon-arc chamber

    For tests in the UV chamber, we use exposure using three types of lamps to choose from: UVA-340, UVA-351 and UVB-313.

    Fillers and pigments

    Our laboratory conducts extensive tests of pigments, fillers and reinforcements used in dispersion systems of water-based paints and varnishes. We develop individual test programs tailored to the customer’s needs and meeting the expectations regarding the data to be provided from the tests performed.

     

    Below we present examples of tests performed according to standardized test methods, however, their scope and application are each time adjusted to water-based paints and the use of pigments and fillers in architectural dispersion paints and varnishes.

     

    We conduct tests in accordance with test programs established through our experience and knowledge of the characteristics of pigments and fillers and their evaluation in various architectural paint systems.

     

    The subject of our tests and laboratory studies are, among others:

    ·         Titanium dioxide pigments (rutil and anatase, different grades ASTM D476 and ISO 591-1)

    ·         Prime pigments and fillers: e.g. ground and calcinated kaolin, iron oxide pigments, etc.

    ·         Reinforcements and functional fillers: e.g. nepheline syenite, wollastonite, talc, etc.

    ·         Standard fillers: e.g. GCC (ground calcium carbonate), PCC (precipitated calcium carbonate), etc.

    Paint preservatives

    Microbiological tests are a new item in our offer. The scope includes testing programs for dispersion paints for the development of formulation, biocides dose levels test by “in-can” tests as and tests of dried coatings for the development of film preservatives against mold, fungus and algae growth.

     

    “In-can” microbiological tests are carried out on test organisms Klebsiela aerogenes (ATCC #13048), Pseudomonas aeruginosa (ATCC #10145) and additional Bacillus subtilus (ATCC #27328) and other organisms agreed with the client. In the field of tests of coatings in terms of fungal and algae growth, tests are carried out on coatings subjected to natural and artificial weathering processes and other operations aimed at washing out components from the coatings so that the test is carried out with reference to the coatings operated after a specified time.
