Packaging & Availability

Standard Packaging

STEPWET DOS 70 is available in drums (440 lb, 200 kg), tote (2200 lb, 1000 kg), and in bulk quantities.

Storage & Handling

Storage & Handling

Normal safety precautions (i.e., gloves and safety goggles) should be employed when handing STEPWET DOS 70. Contact with eyes, nose or prolonged contact with skin should be avoided. Wash thoroughly after handling STEPWET DOS 70. It is recommended that STEPWET DOS 70 be stored in sealed containers kept in a well ventilated area away from sparks, fire and open flame. Avoid overheating or freezing. Equipment should be grounded when transferring or using material. Drums should be vented during heating to avoid excessive pressure build up.

Non-Bulk Storage Recommendations

STEPWET DOS 70 should be stored in closed containers and kept in a cool, dry place away from incompatible materials (see Section 10 of the SDS). If material is frozen it should be heated gently and stirred to ensure it is homogeneous before use. Product temperatures over 104°F (40°C) are not recommended.

Bulk Storage Recommendations

STEPWET DOS 70 should be stored in vessels of 316 stainless steel or glass fiber-reinforced polyester tanks. Many oven cured phenolic and epoxy/phenolic limings may also be used. Elevated storage temperature may be desirable to maintain ease of pumping. Temperatures up to 104°F (40°C) can be maintained for long periods of time without degradation of the product.

Workplace Exposure

Occupational exposure can occur primarily through skin contact or via inhalation of vapors and mists. Engineering controls, personal protective equipment, and other workplace practices should be used to control these exposures.
