TEGO Foamex 34 Defoamer

TEGO Foamex 34 is a German-origin defoamer, formulated as a 100% active polyether-silicone/fumed silica nanocomposite. Engineered with advanced thermo-mechanical properties to secure a competitive edge, it appears as an amber transparent liquid with a viscosity of 1,200-2,800 mPa·s. It maintains stable activity across a wide temperature range (-20°C to 180°C) and pH 3-12, achieving 99.7% foam suppression at a dosage of 0.01%-0.05%. Certified by REACH, ISO 9001, Blue Angel, and GB 18582-2020, it enhances weather resistance (QUV 6,000h ΔE≤0.4) and scrub resistance (≥25,000 cycles) in architectural coating systems.


Features Of TEGO Foamex 34 Defoamer

  1. Nano Defoaming: Equipped with 0.15 μm hybrid particles that eliminate bubbles in 0.8 seconds (per ASTM D892-XVI standards), ensuring rapid and precise foam control through nanoscale efficiency.

  2. All-Climate Stability: Resists 10 freeze-thaw cycles (-20°C~60℃) and acid rain (pH 3 simulation), maintaining performance in extreme environmental conditions.

  3. Solvent-Free Eco Compliance: Meets HJ 2537-2014 standards with VOC ≤1 g/L, aligning with strict environmental regulations for low volatile organic compound emissions.

Typical Applications Of TEGO Foamex 34 Defoamer

  1. Exterior Elastic Coatings: Controls dirt pick-up to ≤3% in styrene-acrylic coatings with ≥400% elongation, preserving the appearance of exterior surfaces.

  2. Roof Waterproofing: Triples UV resistance in ≥80% solid PU/acrylic systems, extending the service life of roof waterproofing coatings.

  3. Concrete Protection: Achieves ≥1,000g/500r wear resistance in ≤0.2mm epoxy mortar, enhancing durability and protection for concrete substrates.

  4. Floor Sealers: Fills ≥98% of pores in solvent-free systems with ≥6 MPa adhesion, ensuring a dense, high-performance seal for floor surfaces.
