DOW CHEMICAL CO.: Specialty Isocyanate (11/9/09)

November 9, 2009

Dow has commercially launched ECHELONTM MU 290 specialty isocyanate, a uretonimine-modified methylene diphenyl diisocyanate (MDI)-based solution for adhesives, sealants, elastomers and coatings applications. ECHELON MU 290 offers a number of benefits including improved clarity and greater handling and storage flexibility.

“By expanding our ECHELON family with this new product, Dow is demonstrating its commitment to bringing new and differentiated materials for use in adhesives, sealants, coatings, and elastomers,” said Janet English, Dow Polyurethanes’ global marketing manager for adhesives, sealants, and elastomers.

ECHELON MU 290 features innovative chemistry, improved shelf life and reduced emissions compared to conventional Dow products. ECHELON MU 290 also offers good compatibility for mixing and improved clarity for the creation of products with lighter color requirements. ECHELON MU 290 can be used for the production of quasi and full prepolymers, and also for two-component urethane coatings, adhesives, sealants, and solid and microcellular elastomers.

From a material handling and usage standpoint, ECHELON MU 290 is a liquid product offering improved shelf life and low-temperature flexibility, allowing it to be stored more economically and conveniently at room temperature than pure MDI. Its low-temperature storage stability alleviates concerns associated with the crystallization of pure MDI during shipping and handling.
