TEGO Foamex 810 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 a milky homogeneous liquid with a viscosity of 400-900 mPa·s. It maintains stable activity under pH 2-12 and temperatures ≤95°C, achieving 99.5% foam suppression at a dosage of 0.02%-0.1%. Certified by REACH, ISO 9001, Blue Angel, and GB 18582-2020, it enhances gloss (60°≥95 GU) and scratch resistance (≥2H) in waterborne industrial coatings and high-gloss systems.
Nano Defoaming: Equipped with 0.25 μm hybrid particles that eliminate bubbles in 1.2 seconds (per ASTM D892-XV standards), ensuring efficient and precise foam control through advanced nanoscale design.
Universal Compatibility: Stable in 30-80% solid acrylic/fluorocarbon emulsions, adapting to a range of water-based formulations with varying solid contents and resin types.
Zero Silicone Migration: Passes FTIR/GC-MS residue tests, eliminating concerns of silicone-related contamination or surface defects in sensitive applications.
Waterborne Metallic Paints: Controls aluminum flake orientation (10-20 μm) with a DOI (Distinctness of Image) ≥97, ensuring a uniform, high-gloss metallic finish.
Heavy-Duty Equipment Topcoats: Achieves an orange peel Ra≤0.1 μm in acrylic PU coatings resistant to ≥1,500h salt spray, enhancing both aesthetics and durability for industrial equipment.
High-Gloss Wood Varnishes: Maintains ≥98% transmittance in UV-cured systems (≥350 mJ/cm²), preserving clarity and high gloss in premium wood finishes.
Container Coatings: Withstands ≥3,000h damp heat in ≥80% zinc-rich epoxy primers, providing long-term protection for container surfaces in harsh environments.
