Blocked Technology

LANXESS Urethane Systems, a world leader in polyurethane solutions, offers blocked prepolymers that are used in 1K and 2K systems for elastomers, coatings and binders. These heat cured systems provide superior processing and productivity with controlled curing for virtually infinite pot life at room temperature. There is no need for mixing, weighing, or blending, making them easy to use and reducing waste and material handling.

Blocked prepolymers deliver enhanced performance, they are resilient to side effects caused by atmospheric moisture and traces of water in coating solvents and other ingredients. Due to blocking technology they can be formulated with non-traditional raw materials, such as new curative types, enabling properties that are not possible with conventional blocked prepolymers. In their blocked state, no exposure to free isocyanates occurs.

LANXESS is at the forefront of blocked prepolymer technology and our products, designed as solvent-borne and 100% solids, meet the requirements of high performance elastomer, coating and binder formulations across a wide range of application areas.
