Protecting the integrity of paints from the growth of microorganisms is a challenge that we at Mathiesen Group take very seriously. Because of this, we have created solid strategic alliances with World Leading Companies in Biocidal formulation that always ensure the protection of the paints.
In this article, we want to tell you about the microorganism attack that can affect the quality of finished paints during their storage time and the protection you want to offer to the paints once applied, that is, in the dry film.
IN CAN protection: Protection during storage inside the container
As you know, aqueous paints are composed of multiple raw materials sensitive to microbial growth; depending on the manufacturing medium, we obtain the perfect conditions for their growth and proliferation.
To select the most suitable biocides, we must consider the production process and aspects such as manufacturing conditions, including machinery, processing water, raw materials, temperature conditions, pH, and labor. In addition, it is vital to identify the ideal moment to incorporate the biocide(s) in the formulation and the appropriate dosage, which must consider the time and storage conditions of the product, both in its warehouses and stores, until its final application.
At Mathiesen Group, we offer a wide variety of active ingredients for IN CAN protection, from products with combinations of:
- VOC-free options.
- Formaldehyde-free options.
This places us at the forefront of Global Regulations.
The breadth of the portfolio of biocides we manage allows us to have broad fields of application. Active ingredients in paints are also used for microbial protection in other areas of industry, such as paper, adhesives, water treatment, personal and home care, and leather, among others.
DRY FILM protection
To correctly select the biocide that will protect the dried paint film, we must consider not only the substrate on which the paint will be applied but also its environment, since factors such as humidity, UV rays (which cause discoloration), weather conditions and variations, exposure to washing (leaching), common areas closest to the application area, are vital elements to ensure the proper performance of the paint once it has been applied.
Therefore, the Dry Film Biocides that we offer respond to specifications such as:
- Low toxicity
- Low solubility in water to prevent leaching
- Low volatility
- Light stability
- Compatibility with different paint formulations
The innovative formulations we offer our customers are successfully used worldwide to meet such demanding needs as areas close to forests with high humidity, highly corrosive coastal zones, and tropical regions with abundant rainfall.
We highlight in our portfolio active ingredients such as:
- Zinc Piritione
Our biocides are widely used to protect interior and exterior paint applications for different substrates and requirements.
We have formulations for architectural and wood paints, among other applications, and molecules to develop antibacterial paints for applications in schools, hospitals, or kindergartens.
