NEW ADIPRENE® DURACAST™ FROM CHEMTURA URETHANES:
LARGER, MORE DURABLE PARTS WITH TOTAL COST IMPROVEMENT

Chemtura Corporation (NYSE:CEM) literally recasts the rules of urethane manufacturing with new Adiprene® Duracast™ Two-Component Urethane System.

Now achievable: Parts of all sizes, from grams to tons

This groundbreaking advancement enables customers to pour parts of all sizes, including some of the largest, most intricate parts ever—all with greater ease, toughness and durability than ever before possible.

A major step forward in processing ease and productivity

The two components of Adiprene® Duracast™, with its proprietary curative, offer high performance through superior phase segregation.

With no MOCA or BDO cures, Adiprene® Duracast™ delivers significantly longer pot life and quick demold times. As a result, manufacturers gain tighter control over ratio and waste—and higher productivity at lower cost.

A health and safety advancement

No TDI and no MOCA also means improved environmental health and safety, especially in handling. Workers do not have to deal with dust or melting issues. The four-step process is easy to learn, reducing human error while raising quality standards.

No major technology investment needed

Manufacturers can start using Adiprene® Duracast™ without investing in major new mix technology. It works in most applications without significant changes. It is also easy to automate. These factors contribute to defect-free parts.

More potential for material price stability

With no TDI and no MOCA, Adiprene® Duracast™ has the potential for better long-term price stability.

Total improvement in process, product and cost

“Adiprene® Duracast™ demonstrates total improvement in process, product and cost,” says Matthew Hellstern, VP, Chemtura Urethanes. “With the flexibility of making large or small parts with fast or slow cures, customers may now be able to capitalize on applications that were once too difficult to produce with cast urethane or rubber.”
