Baydur 660 IBS is a black-pigmented, rigid polyurethane structural foam system used in the reaction injection molding (RIM) process. This system incorporates a specially engineered interactive blowing system (IBS) and is supplied as two reactive liquid components. Component A is a polymeric diphenylmethane diisocyanate (PMDI), and Compo- nent B is a formulated polyol system containing no CFC- or HCFC-blowing additives. Note: Component B should be agitated thoroughly prior to delivery of contents of the drum to the day tank due to possible pigment settling.

The Baydur 660 IBS system was designed for general-purpose applications and is used in industrial and recreational markets. The applications typically take advantage of the material's strength, excellent surface finish, and large part capability. As with any product, use of the Baydur 660 IBS system in a given application must be tested (including field testing, etc.) in advance by the user to determine suitability.
