Price Increase Announcement

Dear Valued Customer,

Effective on all shipments on or after June 1, 2026, or as contracts allow, COIM USA, Inc. is increasing the selling prices of its Isoexter polyester polyols as follows:

• Isoexter polyester polyols for rigid board applications: $0.09/lb.

• Isoexter polyester polyols for spray foam and pour in place applications: $0.09/lb.

This increase is needed to offset increases in the cost of raw materials.

We appreciate the business partnership between our companies, and your account manager will contact you shortly to discuss the specifics of this increase.

Sincerely,

Robert Tauchen
Vice President Polyurethanes
