1630 Fluorocarbon Surfactant Antifog Formula Optimization
Abstract: This article focuses on the directly implementable formula optimization of antifog liquid and antifog cloth impregnating liquid, taking 1630 fluorocarbon surfactant as the core functional raw material. It provides two sets of practical formulas (classic version and long-acting wear-resistant version) and a simple operation process for antifog cloth preparation, while targeting and solving the core pain points in the antifog industry.

Formula Optimization Scheme (Antifog Liquid / Antifog Cloth Impregnating Liquid, Directly Implementable)
Taking 1630 fluorocarbon surfactant as the core, combined with practical application scenarios of antifog lenses and antifog cloths, two sets of directly implementable formulas are developed, and the preparation process of antifog cloth is simplified to meet the needs of industrial mass production and small-batch trial production. All formulas have clear component proportions and detailed function explanations, which can be put into use without additional formula adjustment.
1. Basic Formula (Classic Version, Suitable for Ordinary Lenses, Antifog Duration ≥8 Hours)
This formula is cost-effective, simple to prepare, and suitable for ordinary resin, glass lenses (non-coated), and daily-use antifog cloths. It can achieve stable antifog effect for more than 8 hours, meeting the basic daily needs.
Components | Mass Fraction | Function |
|---|---|---|
1630 Fluorocarbon Surfactant | 0.1%–0.3% | Core antifog component, reducing surface tension to inhibit fog formation |
Polyether Modified Polysiloxane (e.g., BYK-3450) | 0.2%–0.5% | Synergistic spreading, extending antifog duration and improving film formation |
Isopropanol / Anhydrous Ethanol | 20%–30% | Solvent, fast-drying, enhancing permeability of the formula |
Glycerin / Sorbitol | 1%–2% | Moisturizing, preventing water film cracking and improving stability |
Deionized Water | Balance | Carrier, ensuring the formula is uniform and stable |
2. Optimized Formula (Long-Acting Wear-Resistant Version, Suitable for High-End Coated Lenses, Antifog Duration ≥12 Hours)
Core Improvement: Introduce acrylic ester crosslinking agent (0.3%–0.8%) + modified nano-SiO₂ (0.1%–0.2%) to enhance film adhesion and wear resistance. The antifog effect can still be maintained after 25 wipes, which is suitable for high-end coated lenses (anti-blue light, anti-reflection, photochromic films) and high-demand antifog scenarios.
Components | Mass Fraction | Function |
|---|---|---|
1630 Fluorocarbon Surfactant | 0.2%–0.4% | Core antifog component, with hydrophobic and oleophobic properties |
Polyether Modified Polysiloxane | 0.3%–0.6% | Synergistic antifog, improving leveling and avoiding film shrinkage |
Acrylic Ester Polymer (Crosslinking Agent) | 0.3%–0.8% | Enhancing film stability and resistance to water dispersion |
Modified Nano-SiO₂ | 0.1%–0.2% | Improving wear resistance and light transmittance of the film |
Isopropanol | 25%–35% | Fast-drying solvent, no residue after drying |
Phenoxyethanol (Preservative) | 0.1% | Antibacterial, extending the shelf life of the formula |
Deionized Water | Balance | System carrier, ensuring uniform dissolution of all components |
3. Antifog Cloth Preparation Process (Simple and Easy to Operate)
The process is simple, no complex equipment is required, and it can be operated manually or by small-scale equipment, which is suitable for rapid production.
Impregnating Liquid Preparation: Mix all components according to the optimized formula, stir for 30 minutes until clear and transparent (pH 6–7, avoiding corrosion of lens coating).
Substrate Selection: Choose microfiber suede / island fiber cloth (thickness 0.5–1 mm, porosity ≥80%) to ensure sufficient adsorption capacity and softness, avoiding scratches on the lens surface.
Impregnation and Drying: Immerse the fiber cloth into the impregnating liquid (liquid-to-material ratio 1:1.2–1.4), soak for 5–10 minutes, dry at 60℃ at low temperature (avoiding decomposition of the fluorocarbon chain of 1630), and seal and package after drying.
IV. Core Points of Formula Optimization (Solving Industry Pain Points)
Aiming at the common pain points in the current antifog product industry, targeted optimization schemes are proposed based on the characteristics of 1630 fluorocarbon surfactant, which can effectively improve product performance and market competitiveness.
1. Pain Point 1: Short Antifog Duration (Ordinary Formulas Fail in 2–4 Hours)
Optimization Scheme: Compound 1630 fluorocarbon surfactant with polyether modified polysiloxane at a ratio of 1:1.5–1:2. The two components have a synergistic effect, which can jointly reduce the surface tension of the lens, improve the stability of the film layer, and extend the antifog duration from 4 hours to more than 12 hours.
2. Pain Point 2: Poor Adaptability to High-End Coated Lenses (Easy to Leave Marks and Damage the Coating)
Optimization Scheme: Control the addition amount of 1630 fluorocarbon surfactant ≤0.4%, and match it with low-foam polyether modified polysiloxane to avoid erosion of the hydrophobic coating by high-concentration fluorocarbon surfactant. After wiping, there is no residue or watermark, and the light transmittance is ≥99%, which is compatible with all types of high-end coated lenses.
3. Pain Point 3: Difficulty in Compatibility Between Antifog and Cleaning (Strong Antifog but Weak Cleaning)
Optimization Scheme: Add 0.2%–0.5% alkyl glycoside (APG) to the formula, which can take into account both antifog and decontamination functions. It can effectively remove fingerprints, oil stains and other contaminants on the lens surface, and the lens is clean and transparent after wiping without affecting the antifog effect of 1630 fluorocarbon surfactant.
Notes for Implementation
1. All components should be mixed in sequence: first add deionized water, then add solvents (isopropanol/anhydrous ethanol), stir evenly, then add 1630 fluorocarbon surfactant and other additives, and finally stir until clear.
2. The drying temperature of the antifog cloth should not exceed 70℃, so as to prevent the decomposition of the fluorocarbon chain of 1630 and the loss of antifog performance.
3. The prepared antifog liquid and antifog cloth should be sealed and stored in a cool and dry place, avoiding direct sunlight and high temperature, and the shelf life can reach 6–12 months.
