Acclaim 6300 polyol is a 6,000-molecular-weight triol based on propylene oxide. This high-performance, low-monol polyether is prepared with Covestro's proprietary IMPACT® technology, using a patented organo-metallic propoxylation catalyst. The terminal end-groups are predominantly secondary hydroxyls and have a relatively low reactivity. This polyol is acidified with a low level of phosphoric acid, making it suitable for use in isocyanate-terminated prepolymers.

Acclaim 6300 polyol is used in polyurethane and other applications, including cast elastomers, sealants, adhesives, epoxy flexibilizers, defoamers, reaction injection molding (RIM), lubricants, crude oil e-emulsifiers and plasticizers. As with any product, use of Acclaim 6300 polyol in a given application must be tested (including but not limited to field testing) in advance by the user to determine suitability.

Acclaim 6300 polyol is a complementary product to Acclaim 4200 polyol, an Ultra-low monol diol with the same equivalent weight. Overall polyol functionality can easily be varied by blending these two polyols. This polyol contains extremely low levels of monol. In some polyurethane systems, formulation changes, such as reducing the crosslinking level or changing the hard-segment content, may be necessary to maximize the benefits of using Acclaim polyols.
