Packaging & Availability
- Standard Packaging
POLYSTEP TD-189 is available in bulk quantities.
Storage & Handling
- Storage & Handling
Normal safety precautions (i.e., gloves and safety goggles) should be employed when handling POLYSTEP TD series surfactants. Contact with the eyes and prolonged contact with the skin should be avoided. Wash thoroughly after handling material.
Bulk Storage Information
Stainless steel and glass fiber-reinforced polyester tanks are recommended. Many oven-cured phenolic and epoxy/phenolic linings may also be used. Elevated storage temperature may be 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. TD-189 is solid at temperatures below 85°F (29°C). They 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. Product temperatures over 130°F (54°C) are not recommended.
