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.

It functions as both a crosslinker and a rheology modifier, giving formulators control over network density and flow behavior in a single building block for various industrial applications.

In polyurethane and epoxy coatings, this chemical acts as a chain extender or crosslinking diol, contributing to film hardness and chemical resistance without requiring additional rheology additives.

Adhesive and sealant manufacturers incorporate it to tune cure density and improve substrate adhesion in structural and elastic bond lines across diverse manufacturing sectors.

In industrial cleaning formulations, its surfactant-compatible structure supports wetting and leveling performance across hard-surface products, ensuring consistent results in commercial cleaning environments.

Polymer producers also use it as a reactive monomer to introduce acetylenic backbone segments that modify flexibility and crosslink spacing in specialty elastomers and high-performance materials.

The product is supplied as a liquid and is available in technical grade, suited for industrial coating, adhesive, and polymer manufacturing processes requiring reliable chemical inputs.

Bulk and intermediate packaging options are standard across the supply chain to meet the logistical needs of large-scale chemical distributors and industrial end-users globally.
