Intercide™ OBF-25 DIDP

Liquid 25% OIT biocide


Intercide OBF-25 DIDP antimicrobial is a solution of 2- n-octyl-4-isothiazolin-3-one (OIT) in a nonvolatile plasticizer carrier. Intercide OBF-25 DIDP has good resistance to UV but only moderate water leaching resistance which renders the product most suitable for use in a variety of indoor applications such as vinyl film and sheeting, extruded profiles, plastisols, molded goods, organosols, fabric coatings, urethane shoe soles and foams, and similar polymeric systems. This antimicrobial is compatible with most polymer formulations and will not discolor or detract from the protected product’s chemical or physical properties. Intercide antimicrobials can be conveniently incorporated into the formulation during the mixing or compounding processes. Avoid pre-mixing with mixed metal stabilizers; add separately and disperse well to avoid any reducing agent impacting the biocide stability. Typically, Intercide OBF-25 DIDP is recommended at concentrations between 0.15% and 0.36%. For outdoor applications, a level of 0.36% is recommended in vinyl formulations for maximum effectiveness. Intercide OBF-25 DIDP is incorporated into a compound by substituting the required level (0.15% to 0.36%) for an appropriate amount of plasticizer or polyol.
