UBE Urethane Systems manufacture and supply an extensive portfolio of Trixene® and Adiprene® blocked prepolymers and blocked isocyanate crosslinkers.
Our products designed as solvent-borne, water- based and 100% solids meet the requirements of high performance formulations in a wide range of application areas.
For elastomers, 1K and 2K coatings, and binders.
UBE 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.
UBE Urethane Systems are 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.

Product Lines
UBE Urethane Systems manufacture and supply an extensive portfolio of Trixene® and Adiprene® blocked prepolymers that incorporate a broad range of isocyanate and polyol chemistries. They are blocked with a range of blocking agents, including 3,5-dimethylpyrazole (DMP), ε-caprolactam (ε-CAP), methylethylketoxime (MEKO) and diethyl malonate (DEM), which are designed to unblock at specific curing temperatures and can be tailored to your specific needs.

Trixene® offers blocked urethane prepolymers and blocked isocyanates. Trixene® blocked propolomers improve flexibility and impact resistance of epoxy coatings, without compromising chemical resistance. These blocked prepolymers readily react with standard amine hardeners used in 2K epoxy resin formulations, allowing permanent flexibilization of the end product.
-
Trixene® Aqua Blocked Isocyanates are designed for water-based 1K systems. Our range of water-based blocked isocyanate dispersions can be used as crosslinkers and adhesion promoters for coatings and finishes on flexible and hard substrates.
-
Adiprene® blocked urethanes are based on a technology to control the cure of urethane elastomers. This technology effectively blocks the curing reaction until it is heat activated at the optimum time in the process. This enables the pouring of large and complex parts, and even facilitates the use of hand batching. Available in conventional and LF chemistries.
-
Adiprene® K urethane elastomer systems are fully formulated, 1K systems that include the prepolymer, a blocking agent and a curative. Adiprene® K elastomer systems are not limited to LF MDI prepolymers and can be designed with other prepolymer types to tailor the system to your needs.
