Water-based polyurethane dispersion for wood coatings

Mã SP: STV12

SRI RESIN U-9009 is a one-component, water-based polyurethane dispersion synthesized with a self-crosslinking mechanism at room temperature for outdoor and indoor wood substrates.

  • Self-crosslinking: can be applied without need of any hardener (adding a suitable hardener would increase the hardness and chemical resistance properties)
  • Fast drying time
  • High gloss and clarity give the clear natural wood look


+ Resistance properties:

  • With 3 layers of Sri Resin U-9009 on Teak Wood surface by brush method. Testing after air dried for 7 days


Result after 1 hour





Tomato ketchup



4 to 5

50% Ethanol

4 to 5

Shoe polish


       Notes: 1 = bad, 5 = good

  • Very good mar and scratch resistance with the film after air drying for 7 days


+ Application Guidelines:

  • Sri Resin U-9009 can be applied directly on the wooden surface. It has very good wood wettability. If needed, we recommend adding small amount of wetting agents (0.2 to 0.4% and defoamers (0.1 to 0.25%). If some cracking is noticed on substrate, the resin can be formulated to form continues film by adding small amount of forming film agents.
  • Sri Resin U-9009 forms a high gloss film.
