Development of small lot urethane products and contract synthesis.
Block isocyanate / urethane prepolymer
We handle small lot production of block isocyanates and urethane prepolymers from design and prototyping to scale-up.
Bronate Co., Ltd. offers small-lot development and contract synthesis of block isocyanates and urethane prepolymers. We provide comprehensive support for projects that cannot meet performance requirements with existing products, consideration of alternatives for discontinued or hard-to-obtain items, and the development of custom products tailored to specific applications and manufacturing conditions, including raw material selection, recipe development, lab prototyping, physical property evaluation, and scale-up. For block isocyanates, we consider the isocyanate backbone, blocking agents, solvents, curing temperatures, and design compositions according to the intended use. For urethane prepolymers, we design based on conditions such as polyols, isocyanates, NCO content, viscosity, and curing methods. You can consult us from the small-scale prototyping stage to small- to medium-scale production.
