TSCA - Pre-Manufacture Notification (PMN) in process.

A VOC-free, water-borne, UV-curable polyurethane dispersion.

Suggested Uses: Hauthane L-3415 is designed for UV-cured wood and plastic topcoat applications where highly chemical- and abrasion-resistant films are required. Potential end-use applications include automotive plastics, kitchen cabinets and wood flooring.

Characteristics:
  • VOC-free, APEO surfactant free
  • Excellent chemical and stain resistance
  • Forms durable, films under ambient or force-dried conditions
  • Superior abrasion resistance
  • Fast water-release properties

Application

N/A L-3415 may be applied by spray or gravure methods. Films must be dried completely before UV energy cure. UV irradiation is required to attain optimal film properties, but un-cured coating films are durable enough for handling or walking on prior to curing.

Curing

N/A L-3415 must be air-dried, or oven dried (temperature: 150 - 170 ºF; dwell time: 10 minutes) to remove water from the film prior to UV exposure. A photo-initiator must be incorporated into the coating formulation for effective curing. See starting point formulations for suggestions. Exposure guidelines: MPMA lamp - 300 watts/in2, 2.0 - 3.0 second dwell time.
