STEP-FLOW® 26 F
STEP-FLOW® 26 F is a nonionic surfactant providing dispersing and wetting properties in a variety of agricultural formulations. Step-flow 26f is a polyalkylene oxide block copolymer. Step-flow 26f provides primary dispersing and wetting properties in pesticide flowable suspensions. This nonionic dispersant increases the fluidity of flowable suspension concentrates. The hydrophilic properties of the surfactant promote the uniform dispersion of the concentrate when diluted in a broad spectrum of waters and fertilizers.

- Product Features
Nonionic dispersant, also used as a wetting agent; Demonstrated to impart rainfastness benefits to formulations; Hydrophilic properties promote the uniform dispersion of the concentrate when diluted in a broad spectrum of waters and fertilizers.; EPA 40 CFR 180.940a, 180.940c and 180.960 approved.
- Standard Packaging
STEP-FLOW 26F is available in drums (450 lb, 205 kg) and in bulk quantities.
- Handling
Normal safety precautions (i.e. gloves and safety goggles) should be employed when handling STEP-FLOW 26F. Contact with the eyes and prolonged contact with the skin should be avoided. Wash thoroughly after handling materials.; STEP-FLOW 26F which has been stored in drums at temperatures below 45°F (7°C) will solidify. It may be fluidized by warming with a drum heater or in a steam room. Drums should be vented prior to heating to avoid excessive pressure build up.; Bulk Storage Information: It is recommended that STEP-FLOW 26F be stored in stainless steel and glass fiber-reinforced polyester tanks. Many oven-cured phenolic and epoxy/phenolic linings may also be used. Storage temperatures above 90°F (32°C) are desirable to maintain ease of pumping. Temperatures up to 130°F (54°C) can be maintained for long periods of time without degradation of the product.
