DTM4800 Solvent-Based Water, Oil & Stain Repellent Concentrate

DTM4800 is a solvent-based fluorinated resin concentrate designed for durable water, oil, and stain-repellent treatment of leather, textiles, and other suitable substrates. When applied by spraying, it provides long-lasting protection without changing the surface color, hand feel, or breathability of the treated material. It also offers good storage stability and can be diluted at ratios of approximately 1:15 to 1:90, depending on the substrate and required performance.

Product Specifications

Suitable Applications

DTM4800 is suitable for water, oil, and stain-repellent treatment of various substrates, including:

• Leather, including split leather, suede, synthetic leather, and nubuck
• Textile fabrics
• Footwear and shoe components
• Outdoor products
• Paper products
• Stone and selected building materials
• Electronic boards and other suitable substrates

Key Performance Benefits

• Provides durable water, oil, and stain repellency.
• Requires no heat curing, making it suitable for materials or finished products that cannot undergo heat drying.
• Offers good storage stability when stored under recommended conditions.
• Can be diluted at ratios ranging from approximately 1:15 to 1:90, depending on the substrate and required performance.
• Does not alter surface color, hand feel, or breathability when applied by spraying.

Application Method

1. Pre-treatment & Preparation

Before use, the product may be pre-diluted with a suitable solvent to achieve the desired performance. The type, grade, and ratio of solvent will affect solubility and final water/oil repellency. Always test compatibility and solubility before use.

2. Application Equipment

Standard spray equipment can be used. Ensure the spray area is equipped with exhaust ventilation.

3. Spraying Procedure

• Apply evenly by spraying two cross-coats (cross-spray pattern).
• Typical consumption of diluted DTM4800 is approximately 10–12 g per square foot.
• Recommended diluents: petroleum ether (boiling point above 100°C), butyl ester, or dimethyl ester. Petroleum ether is commonly preferred for its lower cost and acceptable odor.

4. Drying

• Room temperature drying is recommended.
• Maximum performance is typically reached after approximately 12 hours at an ambient temperature of 26°C.
• When used immediately after application, performance may reach approximately 80% of the maximum level and continue to develop over time until the intended performance is achieved.

Recommended Processing Parameters

Processing Considerations

• DTM4800 is flammable. Store between 0°C and 50°C and protect from direct sunlight and heat sources.
• Read the Safety Data Sheet (SDS) before use and follow all handling and application instructions.
• Use only in well-ventilated areas. Ensure solvent vapors are properly extracted.
• Avoid contact with skin and eyes. Do not breathe vapors for extended periods.
• Some dyes may be sensitive to solvents and could cause slight color changes; test before full application.
• Wash hands before eating, drinking, or smoking.
• Do not swallow. Follow general chemical storage and transportation safety regulations.
