TMDD Ethoxylate

TMDD Ethoxylate is an ethoxylated acetylenic diol (Venadol series at Esteem: TMDD-20, TMDD-40, TMDD-65, TMDD-85). Ethoxylating the acetylenediol raises HLB and water compatibility while keeping the dynamic wetting and foam control the base diol is known for in coatings and inks.

Venadol TMDD grades step from low-HLB wetting (TMDD-20) toward high-HLB wetting (TMDD-85); higher numbers suit more hydrophilic, ink-friendly systems. Full family context is on the Venadol Gemini Surfactants hub. For grade selection beyond this page, Esteem’s R&D and QA teams work from the application brief rather than a catalogue guess.

Applications

• Waterborne paints and coatings needing dynamic wetting without silicone-style recoat risk (trial first).
• Inks and overprint varnishes where substrate wetting and foam control must coexist.
• Adhesives, pigment dispersions and agro sprays on low-energy surfaces.

How to select the grade

• Start low-HLB for hydrophobic substrates; move up the TMDD ladder if water-phase compatibility fails.
• Acetylenic diols control foam differently from silicone defoamers — check recoat and crater behaviour on your line.
• Name substrate, coating method and foam ceiling on the RFQ.

How to specify on an RFQ

Send the application, the property that must not fail (HLB/emulsion stability, wetting, foam, feel or solubility), target specification, and trial quantity. That lets Esteem match the grade to your test method instead of quoting the nearest catalogue name. Current TDS, SDS and lot COA are shared for qualified enquiries through the document library route.
