Application / Buyer guide
Choose outdoor DWR around the finished textile.
For outdoor and sportswear projects, start with the fabric and its intended use. Surface water repellency, garment waterproofness, breathability and wash durability are separate requirements with different evidence needs.
- Start with
- Substrate and intended use
- Then define
- Process, test and acceptance criteria
- Request
- Current product-specific evidence
Application illustration; not a test result or proof of product performance.
In this guide Open
01 / Project scope
Define what the material needs to do.
ZEODRY is DEZEO's fluorine-free water-repellent finishing ingredient brand. Buyers evaluating a ZEODRY route should provide the fabric construction, processing conditions and target tests, then request the current grade-specific documents and a sample-validation plan. Suitability for a particular fabric must be established through project testing.
This guide defines the project questions. It does not publish or infer a product grade, dosage, curing window, wash-cycle claim or PFAS compliance result.
02 / Buyer checklist
Send a brief that supports a useful technical answer.
- 01Fabric identity
Fiber blend, woven or knitted construction, fabric weight, color and pretreatment.
- 02Process conditions
Finishing or coating route, equipment, drying and curing conditions, and existing auxiliaries.
- 03Performance targets
Specify surface water repellency, waterproofness, breathability, hand and appearance separately.
- 04Durability protocol
Agree the wash and drying procedure, cycles, sample count, retest points and acceptance criteria.
- 05Market and end use
Identify the finished product, destination market, brand specification and customer restrictions.
- 06Product evidence
Request the exact grade's current TDS and SDS, relevant declarations, and traceable trial records.
For current grade information, submit the project context through the controlled document request. A general application guide cannot replace the relevant technical file.
03 / Validation
Keep each conclusion tied to its evidence.
| Evaluation | Agree before testing | Do not infer |
|---|---|---|
| Surface water repellency | Test method, pretreatment, wash state and acceptance criterion. | One fabric result applies to every construction, color or batch. |
| Wash durability | Washing and drying program, cycle count and repeat testing. | A laboratory result predicts every consumer-care condition. |
| Finished-product waterproofness | Membrane or coating, laminate, seams and an appropriate finished-construction test. | A water-repellent finish alone makes a garment waterproof. |
| Market requirements | Named product, destination market, customer limits and responsible reviewer. | A surface-performance result establishes market compliance. |
Retain sample identity, document version, method and conditions. A result should not be transferred to another substrate, construction, batch or market without an appropriate review.
04 / Buyer questions
Questions to resolve before selection.
Does fluorine-free DWR make an outdoor garment waterproof?
No. A surface water-repellent finish and finished-garment waterproofness are different properties. Membranes, coatings, laminates and seams must be assessed with the applicable construction and test method.
How should buyers select a ZEODRY grade for sportswear?
Provide the fabric, pretreatment, processing route, target performance, wash protocol and destination market. Request the current TDS and SDS for the proposed grade and validate it on the actual fabric before approving a selection.
Can a fluorine-free label alone confirm every PFAS requirement?
No. A fluorine-free description does not by itself establish compliance with every customer or regulatory PFAS definition. The named product, declaration, analytical scope and intended market must be reviewed together.
