VOC-Free In-Can Preservative for Aqueous Paints & Coatings
PREVENTOL® P 91MV is a high-performance in-can preservative designed to protect aqueous paints, coatings, and industrial preparations from microbial contamination throughout their shelf life. Formulated as a colorless to slightly yellow aqueous solution, it combines two complementary active substances — 2-bromo-2-nitropropane-1,3-diol (bronopol) and isothiazolinones — to deliver broad-spectrum antimicrobial activity against bacteria, mould fungi, and yeasts.
This dual-active system makes PREVENTOL® P 91MV particularly effective in demanding aqueous environments where single-active preservatives may fall short. Its formulation is VOC-free, making it suitable for low-emission and environmentally conscious coating systems, and its low-odor profile ensures a comfortable handling experience in production settings.
One of the key technical advantages of PREVENTOL® P 91MV is its compatibility with salt-sensitive substrates, such as polymer emulsions — a critical consideration in architectural and industrial coating formulations where ionic sensitivity can affect product stability. The product is supplied ready-to-use in liquid form, enabling direct, undiluted addition to the formulation without the need for pre-dissolution steps, which simplifies dosing and reduces process complexity.
Typical applications include aqueous paints and architectural coatings, synthetic adhesives and sealants, polymer emulsions, mineral slurries, concrete admixtures, lithographic fluids, and industrial cleaners. With a shelf life of 2 years, PREVENTOL® P 91MV offers reliable long-term performance as part of a robust in-can preservation strategy.
