FORMALDEHYDE is a ready-to-use formaldehyde-based preservative designed for incorporation into liquid concrete admixtures. It effectively prevents microbial growth (bacteria, yeast, molds) during storage and transport, ensuring long-term stability, consistent viscosity, and reliable performance of water-reducing, set-retarding, and PCE-based admixtures. This product is intended for admixture manufacturing only, not for direct addition into concrete.
