STEPCOTE W-133 is an effective wetting agent for use in waterborne coatings. It can be incorporated during the letdown phase of production or post added to the final formulation. Typical use level, based on active content, is 2 – 6 lbs/100 gallons, however, optimal dosing should be determined by performing a ladder study. STEPCOTE W-133, although primarily a wetting agent, may positively impact the following coatings properties:
- Gloss
- Temperature Stability
- Color Acceptance
- Wet Scrub Resistance
- Hiding
- Washability

- Standard Packaging
STEPCOTE W-133 is available in bulk quantities.
Storage & Handling
- Storage & Handling
- Non-Bulk Storage Recommendations: STEPCOTE W-133 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 may be fluidized by warming with a drum heated or in a steam room. Drums should be vented prior to heating to avoid excessive pressure build up.
- Bulk Storage Recommendations: STEPCOTE W-133 should be stored in vessels of 316 stainless steel, but carbon steel is adequate assuming effective moisture exclusion. Elevated storage temperature may be desirable to maintain ease of pumping.
- Product temperatures over 50 °C (122°F) are not recommended.
- Normal safety precautions (i.e., gloves and safety goggles) should be employed when handling STEPCOTE W-133. Contact with eyes, nose or prolonged contact with skin should be avoided. Wash thoroughly after handling STEPCOTE W-133.
