ROCIMA™ BT NV2 is a zero-VOC, aqueous dispersion 1,2-Benzisothiazolin-3-one (BIT) in-can preservative. It offers broad-spectrum protection against bacteria and fungi in a wide variety of industrial and agricultural formulations.
ROCIMA™ BT NV2 is a benzothiazolinone-based preservative similar to ROCIMA™ BT 2S and KORALONE™ B-119 but formulated as an aqueous dispersion. This product's key feature is having zero VOC content, making it an excellent choice for low-VOC formulations.
Like other BIT-based preservatives, ROCIMA™ BT NV2 offers broad-spectrum activity against bacteria and fungi (yeast and mold). It also provides stability at high temperatures up to 150°C and in the presence of amines. ROCIMA™ BT NV2 is suitable over a wide pH range of 4 to 12.
ROCIMA™ BT NV2 exhibits a high level of microbial protection against common bacteria in aqueous-based formulations. ROCIMA™ BT NV2 is EPA-approved and recommended for use in paints, coatings, adhesives, building materials, and pesticide formulations. More information about approved applications and use levels is available on the label.
