D.R. Coats Ink & Resins Pvt. Ltd. (DRC) offers high-performance chain extenders specifically engineered for European industries working with epoxy and polyurea systems. Our Dromine™ product range provides excellent reactivity and mechanical strength for demanding formulations.
Dromine™ 100 is a clear yellow liquid with low viscosity (120-200 cP) and a molecular weight of 178. It serves as a reliable curing agent for epoxy resins and as a chain extender for polyurea elastomers, ensuring enhanced durability, flexibility, and thermal stability in final applications.
Dromine™ 300 is a clear amber liquid with a higher viscosity range (350-500 cP) and molecular weight of 214. It is specially formulated as a chain extender for polyurea elastomers, offering improved elongation and tensile strength, which are essential for coatings, sealants, and elastomeric applications.
Both products are designed to meet the needs of advanced industrial formulations and are compatible with modern production requirements. With proven performance and consistent quality, DRC’s chain extenders contribute to reliable processing and long-lasting end-use properties in polyurea-based systems. Industries across Europe can benefit from these robust additives in coatings, adhesives, and elastomeric products.
