Product Description
Acclaim 4220N polyol is a 4,000-molecular-weight diol based on propylene oxide and ethylene 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 have a high percentage of primary hydroxyl end-groups giving a relatively high reactivity with isocyanates. Because this product is not acidified, care must be taken using it in isocyanate-terminated prepolymers.

Acclaim 4220N polyol is used in polyurethane and other urethane applications, including cast elastomers, sealants, adhesives, epoxy flexibilizers, defoamers, reaction injection molding (RIM), lubricants, crude oil de-emulsifiers, and plasticizers. As with any product, the use of Acclaim 4220N polyol in a given application must be tested (including but not limited to field testing) in advance by the user to determine suitability.

Acclaim 4220N polyol is a complementary product to Acclaim 6320N polyol, an ultra-low monol ethylene- oxide capped triol with the same equivalent weight. Overall polyol functionality can easily be varied by blending these two polyols. Acclaim 4220N polyol should be acidified prior to use in prepolymer applications This polyol contains extremely low levels of monol. In some polyurethane systems, formulation changes, such as reducing the cross-linking level or changing the hard- segment content, may be necessary to maximize the benefits of using Acclaim polyols.
