Desmorapid

Desmorapid (CAS 15875-13-5), also marketed as Lupragen N 600, is a tertiary amine catalyst that accelerates polyurethane cure reactions.

Where is Desmorapid used?

• Flexible and rigid polyurethane foam: promotes the isocyanate-water reaction, enabling consistent cell structure and rise times
• Adhesives and sealants: shortens open time and improves green strength in one- and two-component PU systems
• Coatings: supports crosslink density development in moisture-cure and two-pack urethane formulations
• Industrial cleaning and surface treatment: pH buffer and process aid where controlled alkalinity is required
• It drives both the blowing and gelling reactions in foam and elastomer systems.

Good to know: Buyers should confirm active content and amine value with the supplier to ensure batch-to-batch consistency in reactive systems.

Commercial specifications

• Liquid, typically handled in drums and intermediate bulk containers suited to industrial-scale dosing
