Description

Bis(Oxiranylmethyl) (Methylenedi-p-Phenylene)Biscarbamate is a multifunctional epoxy-functionalized carbamate crosslinker widely employed in high-performance thermoset formulations. It delivers exceptional thermal stability, chemical resistance, and adhesion enhancement—making it critical for advanced coating, composite, and adhesive systems requiring rapid cure kinetics and long-term durability. This compound is essential for industrial manufacturers developing automotive clearcoats, aerospace prepregs, electronic encapsulants, and high-gloss industrial finishes. Bis(Oxiranylmethyl) (Methylenedi-p-Phenylene)Biscarbamate CAS NO 85896-20-4 serves as a key building block where precise stoichiometric control of epoxy–carbamate reactivity enables tailored network density and mechanical performance.

Application

• High-solids and low-VOC automotive clearcoats requiring rapid ambient or forced-dry cure
• Crosslinking agent in powder coatings for architectural aluminum and appliance finishes
• Reactive diluent and co-crosslinker in epoxy–amine and epoxy–carbamate hybrid composites
• Surface-modification intermediate for epoxy-functionalized silica and metal oxide nanoparticles
• Adhesion promoter in structural adhesives for metal-to-composite bonding
• Monomer in UV/thermal dual-cure inkjet and 3D printing resins
• Chemical intermediate for synthesizing polyfunctional epoxy curing agents
• Performance enhancer in radiation-curable coil coatings for flexible packaging substrates

Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards. Certificates of Analysis (COA) are available upon request. All batches conform to ISO 9001-certified manufacturing protocols and meet stringent purity and consistency benchmarks for industrial crosslinkers—including strict control of residual solvents, epoxide equivalent weight (EEW), and volatile organic content (VOC). Testing includes HPLC purity verification, FT-IR identity confirmation, epoxide titration, and moisture analysis by Karl Fischer.

Storage

Preserve in a tightly closed container, protected from light. Store at 15–25°C in a dry, well-ventilated area. Due to its hygroscopic nature, minimize exposure to ambient humidity—use desiccant-equipped secondary packaging during long-term storage. Avoid contact with strong acids, strong alkalis, and fluorides.
