Waterproof fabrics were initially developed for use in clothing and protective apparel production, and are now widely used in the manufacturing of sportswear, travel bags, tents, and more. Additionally, waterproof and moisture-permeable fabrics can serve as wound dressings to keep injured skin dry and prevent bacterial invasion. They are also used as surgical gowns and dust-proof workwear in cleanroom environments.

Advantages of Waterproofing Agent:

1. Eco-friendly: Contains no APEO (alkylphenol ethoxylates), no PFOS, and PFOA content below 1ppm 

2. Cost-effective: Very low dosage required for treating synthetic fabrics such as polyester and nylon 

3. Product is a non-flammable water-based emulsion 

4. Recommended for water, oil, and stain repellent finishing of fabrics like polyester, nylon, and polyester-cotton blends 

5. Wide production applicability: The water and oil repellency of DTM-648 is not sensitive to the pH of the working solution 

6. Fabrics gain protective functions while maintaining their natural hand feel, appearance, and breathability 

7. Can be applied via spraying, foaming, knife coating, wet roller, padding, exhaust methods, etc. 

8. Excellent stability when used in combination with other textile auxiliaries

Packaging Specifications For pilot purchases, 5KG, 10KG, and 20KG packaging options are available. For regular mass production purchases, only 60KG blue plastic drum packaging is provided.

Usage Instructions:

1. First, add the required amount of DTM-648 waterproofing agent into a clean mixing container, then slowly add the required amount of tap water. After adding water, stir at low speed for 5–10 minutes until the solution is uniformly mixed. Avoid generating excessive foam.

2. When used in the same bath with cross-linking agents, penetrants, anti-wrinkle resins, or other auxiliaries, pre-test the compatibility and stability of these agents with DTM-648. Always dilute these products and the waterproofing agent separately before mixing to avoid direct mixing of raw liquids.

Friendly Reminder:

1. It is recommended to wear gloves, goggles, or a face shield to protect hands and eyes. Avoid skin and eye contact. 

2. Before combining with other auxiliaries, conduct preliminary tests to fully confirm compatibility with the mixed chemicals. 

3. Stir the treatment solution slowly during preparation to avoid generating excessive foam. 

4. Fluorinated waterproofing agents may have a darkening effect. Please confirm color changes after processing in advance. 

5. Curing must be thorough; otherwise, optimal protective performance may not be achieved. Pre-test based on equipment conditions. 

6. Use the prepared treatment solution within 12 hours whenever possible. If stored for a long time, confirm its condition before use. 

7. Roller drying is not an ideal method due to the tendency of resin residues to adhere and accumulate on rollers.
