Overview
Acetylenic diol surfactants are a class of low-foaming, high-wetting nonionic surfactants built on the 2,4,7,9-tetramethyl-5-decyne-4,7-diol (TMDD) core. Their rigid alkyne bond rapidly lowers dynamic surface tension, delivering fast substrate wetting without the foam burden typical of conventional nonionic surfactants — ideal for high-speed coating, spraying and printing.
Tianjin Hi-Perferal Advanced Materials Co., Ltd. is a dedicated manufacturer of Toynol® acetylenic diol surfactants, offering TMDD, ethoxylated derivatives and gemini-type products with full technical data and application support.
Key Products
- Toynol® FS-204 — TMDD (CAS 126-86-3), active content ≥98%, 0.1% aqueous static surface tension ~32.8 dyn/cm
- Toynol® FS-204E — acetylenic diol glycol solution for easier handling
- Toynol® FS-204PG — glycol solution, non-ionic, APEO-free
- Toynol® Superwet-320 — ethoxylated acetylenic diol, ultra-low dynamic surface tension
- Toynol® DF-80PG — gemini-type nonionic defoamer/wetting agent
Technical Highlights
- Low dynamic surface tension — FS-204 at 0.1% in water: dynamic ~33.3 dyn/cm, static ~32.8 dyn/cm
- Low foam — acetylenic diol structure minimizes foam generation in high-shear processes
- High active content and consistent quality under ISO 9001
Applications
- Waterborne coatings and inks
- Adhesives and emulsion polymerization
- Metal cleaning and surface treatment
- Wetting-agent building blocks for formulations
