Our product manager is constantly working on adding more exciting chemicals to our portfolio and finding suitable partners for us. In doing so, we attach great importance to long-term, partnership-based cooperation and the best quality. Our team of business people, consisting of Mr. Philipp Runge, Mr. René Wieseotte, Mr. Mourad Elhamdaoui and Ms. Katharina Jagdschian, is at your disposal for all questions regarding offers, prices, quantities, orders, delivery times, documentation and processing.

STOCKMEIER Spezialchemie is always on the lookout for new and innovative products. Longer on the market, but still a speciality, are the LPR products from the company Lorama from Canada.

A cost saving of 5-10 % is assumed, with a simultaneous reduction of the VOC content of solvent-based alkyd resin systems. In addition, the raw materials are largely made from natural raw materials.

The secret lies in the incorporation of up to 40 % water into the formulation with the help of polysaccharide resins. For this purpose, a premix (Emulsion Intermediate) is prepared, which consists of alkyd resin, solvent, defoamer, polysaccharide resin and water. Sounds like extra work, but the emulsion is stable for a long time and can thus be produced for several approaches. Depending on the alkyd resins used, up to 60 % water is possible in this premix. The ground material is prepared as usual and a reduced amount of alkyd resin is added. In the last step, the emulsion Intermediate is added; simple stirring is sufficient here. An addition of 20 % is standard, but can be adjusted individually. The total amount of alkyd resin can be reduced by the amount of polysaccharide resin, which leads to lower costs, but also to a reduced use of solvents and siccatives. The hydroxyl groups of the polysaccharide resin together with the carbonyl groups of the alkyd resin form a high-molecular network, which improves the properties both in the wet paint and in the dry film. These include, among others, a possible increase in viscosity, a lower tendency to run, better adhesion to the substrate, higher hardness and a weaker tendency to yellowing.

New in the distribution of STOCKMEIER Chemie are the products of the Spanish company Chemipol, S. A.

Chemipol has been producing biocides for industry for over 40 years. In the field of coating materials, pot and dry film preservatives are offered. Much emphasis is placed on good advice so that the appropriate product can be selected and offered in each case. In order to find possible sources of contamination such as process water, ingredients, production and filling, Chemipol offers testing in its own laboratory or, for quick self-monitoring, the Chemipol-Biocheck®, which shows both bacteria and fungi.

Three product groups are offered for the coating sector:

Through my personal contact with Mr Hussin. The STOCKMEIER company is very well known in the industry. After initial discussions, I was immediately enthusiastic about the vision and future of STOCKMEIER and wanted to become part of the success story.
