STEPCOTE® W-843

1 of 16 products in this brand
STEPCOTE® W-843 proves its efficacy as a highly capable wetting agent tailor-made for waterborne coatings. Its integration is versatile, being applicable both during the letdown phase of production and as an addition after final formulation. While its central role revolves around enhancing wetting characteristics, it carries the potential to exert a favorable influence on critical coating attributes. These encompass gloss enhancement, bolstering high-temperature block resistance, augmenting color acceptance, and contributing to the effective hiding of the coating.

Storage & Handling

Storage Conditions

It is recommended that STEPCOTE® W-843 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. Normal safety precautions (e.g., gloves and safety goggles) should be employed when handing STEPCOTE® W-843. Contact with eyes, nose or prolonged contact with skin should be avoided. Wash thoroughly after handling STEPCOTE® W-843. See SDS for more information.

STEPCOTE® W-843 must be preserved in its original packaging, carefully closed, safe from freezing, sources of heat and sunlight. Do not store together with alkalis (caustic solutions). STEPCOTE® W-843 reacts with light alloys in the presence of moisture to form hydrogen. Corrosive action on metals. Keep the floor clean and prevent any seepage into the ground.

Ensure good ventilation/exhaustion at the work place and do not inhale gasses, fumes and aerosols. Avoid all contact with the eyes and skin. Wear protective clothing, impermeable gloves and eye/face protection (for example a visor). Keep unprotected persons away. Provide water supplies, ocular fountain
