Storage & Handling

Normal safety precautions (i.e. gloves and safety goggles) should be employed when handling MICRO-STEP H-303. Contact with the eyes and prolonged contact with the skin should be avoided. Wash thoroughly after handling materials.

Bulk Storage Information

It is recommended that MICRO-STEP H-303 be stored in stainless steel and glass fiber-reinforced polyester tanks. 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. MICRO-STEP H-303 which has been stored in drums at temperatures below 60°F (15°C) may thicken or solidify. It may be fluidized by warming with a drum heater or in a steam room. Drums should be vented during heating to avoid excessive pressure build up. Product temperatures over 130°F (54°C) are not recommended.
