Golpanol BEO

Golpanol BEO (CAS 32167-31-0), also known as hydroxyethylated 2-butyne-1,4-diol, is an acetylenic diol ethoxylate supplying reactive hydroxyl functionality for polymer and coating systems.

Where is Golpanol BEO used?

• Polyurethane and epoxy coatings: chain extender or crosslinking diol contributing to film hardness and chemical resistance
• Adhesives and sealants: tunes cure density and improves substrate adhesion in structural and elastic bond lines
• Industrial cleaning: surfactant-compatible structure supports wetting and leveling on hard surfaces
• Polymer production: reactive monomer introducing acetylenic backbone segments that modify flexibility and crosslink spacing in specialty elastomers
• It functions as both a crosslinker and a rheology modifier, giving formulators control over network density and flow behavior.
