Acclaim 8200 polyol is a 8,000-molecular-weight diol based on propylene oxide.
Product description
Applications
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 8200 polyol is used in polyurethane and other applications, including cast elastomers, sealants, epoxy flexibilizers, defoamers, lubricants, crude oil de-emulsifiers and plasticizers. As with any product, use of Acclaim 8200 polyol in a given application must be tested (including but not limited to field testing) in advance by the user to determine suitability.Acclaim 8200 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.

Storage
Acclaim 8200 polyol is slightly hygroscopic and may absorb water. Containers should be kept tightly closed and protected from contamination with moisture and foreign materials, which can adversely affect product quality. This polyol can become quite viscous at low temperatures. For ease of handling, storage temperatures between 20°C (68°F) and 60°C (140°F) are recommended. The shelf life is twelve months after receipt of material by customer, when stored in sealed original containers under conditions stated above.
