ASK Chemicals launches Necowel 900 Series

Ecolabels are influencing buying decisions consumers take in their daily life when purchasing decorative coatings. The formulated product can be certified by independent organisations to increase visibility of their environmental friendliness to the consumer. Even though ecolabels are applied to the finished coating, the raw materials used to formulate this finished product need to comply with the different ecolabels in use by the coatings formulators.

Necowel alkyd emulsions do not contain VOCs nor SVOCs. Usually Necowel alkyd emulsions contain Methylisothiazolinone (MIT) and Benzisothiazolinone (BIT). Necowel 900 Series is free of MIT right from the beginning. This preservative can be adopted to the needs of the customer.

The concentration of PTBBA (P-Tert-Butylbenzoic acid), as a hazardous substance, may not exceed the concentration of 0.01% when applying an ecolabel for a formulated product. With the development of the Necowel 900 Series ASK Chemicals’ R&D team was able to develop a series of alkyd resins that is free of any PTBBA, which makes it ideal to comply with common ecolabel standards.

The newly developed products do not contain any external emulsifiers but achieve excellent shear stability and shelf life. The products offer low odour and high gloss. Excellent rheological behaviour and drying properties make them an ideal binder solution for the formulation of ecolabel compliant decorative coatings.
