Acclaim polyols are high-performance, low-monol polyethers prepared with Covestro’s proprietary IMPACT technology. The terminal end-groups are predominantly secondary hydroxyls and have a relatively low reactivity. Acclaim polyols can be reacted with Desmodur crosslinkers for the formulation of solventborne elastic two-component PU coatings and adhesives with high strength and resistance.
The properties of polyurethanes formulated with Acclaim polyether polyols may be maximized by adjusting the cross-linking level or changing the hard-segment content. Acclaim polyether polyols can provide:
• Extremely low monol levels
• Low unsaturation
• Low water content
• BHT free
• Low basicity and acidity
Acclaim polyether polyols are acidified with a low level of phosphoric acid, making them suitable for use in isocyanate-terminated prepolymers.
