Cas no 3634-83-1 (m-Xylylene Diisocyanate)

m-Xylylene Diisocyanate (m-XDI) is an aromatic diisocyanate characterized by its two reactive isocyanate groups bonded to a meta-xylylene backbone. It is primarily used as a crosslinking agent in polyurethane and polyurea formulations, offering excellent mechanical properties, chemical resistance, and thermal stability. Compared to other diisocyanates, m-XDI provides lower viscosity, facilitating easier processing, and exhibits reduced volatility, enhancing workplace safety. Its meta-substitution pattern contributes to improved hydrolysis resistance and flexibility in cured polymers. m-XDI is particularly valued in coatings, adhesives, and elastomers where durability and performance under demanding conditions are required. Proper handling is essential due to its reactivity and potential sensitization effects.
