Introduction:

As a carbamate biocide, IPBC (3-iodo-2-propynyl-N-butyl carbamate) was originally introduced as a mildewcide for paints, but since 1984 it has gained increasing importance in the wooden packaging industry, where it has found a market in the control of sapstaining fungi. In this role, IPBC and other newer, more environmentally benign biocides, such as quaternary ammonium compounds, have largely replaced the environmentally persistent pentachlorophenol (PCP) salts used historically to treat packaging wood against sapstains, moulds and rot fungi. However, its environmental fate is still not known over ten years after its widespread acceptance as an effective PCP substitute.

IPBC is a low toxicity biocide specifically developed for the complete microbiological protection of water based and solvent based products against algal and fungal spoilage in the dry and wet state. IPBC is a powder product.

Use: IPBC is a fungicide/antimicrobial used as a preservative in paint, adhesives, emulsions, metal cutting fluids, oil recovery drilling mud/packer fluids, plastics, textiles, inks, paper coatings, and wood products. It is also used in residential settings as a wood preservative stain to combat wood rot/decay, and as a preservative in paints. IPBC is also applied to heating, ventilation, and air conditioning (HVAC) ducts and equipment to control mold and fungi; IPBC is effective against fungi and algae.

Use level: The recommended use level of Nipacide IPBC to preserve most product types is normally in the range 0.1-2.0% based on the total weight of the finished product.

Application: IPBC is recommended for a wide range of applications including adhesives, polymer emulsions, MWF and paint where protection against fungi and algae is required in the wet state and dry state.

Storage conditions: IPBC should be stored at temperatures within the range 4-40oC. Containers containing IPBC should not be exposed to direct sunlight. Storage conditions should also be in conformance with applicable legal, fire and insurance regulations.
