- Special Properties and Uses
- SETAQUA® DTM 6850 is a self-crosslinking, APEO and ADH-free, waterborne acrylic copolymer emulsion especially designed for direct-to-metal applications.
- For proper film formation at room temperature this unique, hydrophobic acrylic emulsion requires the addition of hydrophobic coalescing agents to enable perfect film formation, good direct-to-metal adhesion and corrosion resistance performance. The use of hydrophilic coalescing agents in combination with SETAQUA® DTM 6850 is not recommended.
- Dispersing agent ADDITOL XW 6588 is a perfect synergist in combination with SETAQUA® DTM 6850 for the preparation of best-in-class DTM protective coatings. SETAQUA® DTM 6850 requires the use of flash-rust inhibitors for steel substrates. As chemical nature and concentration of flash rust inhibitor systems may significantly influence dry-wet adhesion properties on metals, a careful selection must be made in this respect. Suggested guiding formulations are available on request.
Advantages:
- VOC-free binder
- shear stable
- excellent corrosion resistance performance
- high and stable gloss in salt spray and humidity test
- no need for anti-corrosion pigments or organic adhesion promotor / anticorrosion additives
- broad adhesion spectrum on various substrates including metals, CED coated metals, plastics (PS, PVC, PMMA), wood and composite materials (HPL)
- good mechanical properties
- outstanding early water resistance
- good blocking resistance, high hardness
- very good chemical spot test resistance
- suitable for high pigment loading - fast drying

Technical Details & Test Data
- Compatibility
- In general SETAQUA® DTM 6850 has good compatibility with other anionic and non-ionic WB binders but performance and stability needs to be tested very carefully, especially with respect to corrosion resistance.
- SETAQUA® DTM 6850 is compatible with a wide range of anticorrosion pigments but stability in the final formulation needs to be tested very carefully.

Storage & Handling
- Shelf Life
- 365 Days
- Storage and Handling
- At temperatures up to 40°C storage stability packed in original containers amounts to at least 365 days.
- It is important to protect SETAQUA® DTM 6850 from freezing; at low temperatures it should be stored under "keep from freezing" conditions.
