hydrotuff 5500

HYDROTUFF 5500 is mono-component water-based polyurethane/acrylic dispersion for interior/exterior wood coating. It is developed to provide a hard resistant film with excellent abrasion and high flexibility and environment-friendly.
It is best recommended for coating floor surfaces, furniture, turn pieces, bamboo canes and the like. HYDROTUFF 5500 is available in a satin and semi-glossy finish which gives an excellent smoothness and opacity.
  • Excellent hardness.
  • Flexible
  • Non-toxic/Environment-friendly.
  • Fast-drying.

Coating rate – 8 – 10 m2/L (Coverage will vary depending on the porosity of the surface)

Recoating – Two (2) coats may be sufficient for the ordinary finish, allow 2 hrs. Drying time between coats. Light sanding with 400-600 grit sandpaper is recommended before subsequent coat when recoating time exceeds 8 hrs. and remove traces of wax.

  • The mixture is ready for use and can be applied by brush or spray.  The surface to be coated must be free of dirt and other contaminants.  In the remaking of old woods, it is imperative to remove traces of wax, dirt and other oily matter to ensure perfect adhesion of paints.
  • The first coat can be diluted with 5-10% with clean demineralized water, and allow to dry for an hour before sanding to remove any raised grain.
  • Ensure that HYDROTUFF 5500 is applied uniformly and never leave an unsealed surface to avoid moisture.

HYDROTUFF 5500 has a good resistance without additives.  It is resistant to chemical stabilize from Level 1-B DIN 6881 part 1.  HYDROTUFF 5500 does not contain heavy metal and therefore, it can be used for toys in accordance with European Std’d EN 71-3 for Toy Security.

 

The drying room temperature should not be lower than 15ºC and the humidity must be less than 85ºC.  If the condition is beyond the required temperature, the possibility of slow drying smooth film and less chemical resistance.  It is recommended for a good dry by force drying without humidity starting from normal temperature up to 30ºC. 

Due to the thermoplastic of the water-based resin, the drying during piling is delicate which may result in a different effect.  However, force drying plus Catalyst will improve the risk of piling.
