STEPCOTE® W-125

STEPCOTE® W-125 serves as a highly effective wetting agent suitable for utilization in waterborne coatings. It can be integrated either during the letdown phase of production or added after the final formulation. While its primary role is as a wetting agent, it might also exert a positive influence on various coating properties such as gloss, low foaming, and color acceptance.

Applications

STEPCOTE W-125 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-125, although primarily a wetting agent, may positively impact the following coatings properties:

  • Gloss
  • Low Foaming
  • Color Acceptance

Storage & Handling

Storage & Handling
  • Bulk Storage Information: It is recommended that STEPCOTE W-125 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 32 °C (90 °F) are desirable to maintain ease of pumping. Temperatures up to 54 °C (130 °F) can be maintained for long periods of time without degradation of the product.
  • STEPCOTE W-125 which has been stored in drums at temperatures below 7 °C (45 °F) 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.
  • Normal safety precautions (i.e., gloves and safety goggles) should be employed when handling STEPCOTE W-125. Contact with eyes, nose and prolonged contact with skin should be avoided. Wash thoroughly after handling materials.
