Hesse PERFECT-FILL HDP 5650-9343

Our PERFECT-FILL HDP 5650-9343 has been developed as the preferred system filler for combination with HYDRO-PU RESISTCOLOR HDB 5434x(gloss level)-(colour tone). Its ease of processing and wide area of application, including its suitability for surfaces subject to heavy wear and in damp locations and the like, make it a universal filler throughout interiors. The results of retardancy tests according to IMO and DIN EN 13501-1 are awaited. HYDRO-PU RESIST-FILLcan be sanded by machine and can be recoated using all suitable Hesse lacquer systems.

Information on use

Usage time 2 h / 20 °C
Pot life 2 h / 20 °C
Drying 5 h / 20 °C
Stackable after > 16 h / 20 °C
Complete drying 7 d / 20 °C
Surface preparation Clean, well-seasoned wood, or clean, suitable MDF or plywood base, free from oil, grease, wax and silicones. Sanded as prescribed and free from sanding dust. Depending on the kind of wood and the desired surface effect: graduated raw wood sanding with grit size 120 - 220 and subsequent dedusting. The quality of the wood sanding is a decisive factor for the quality of the final surface. For foil substrates: suitable foil: sanding with grit size 320 - 400 and subsequent dedusting and degreasing, if necessary. The foil quality and the quality of the foil sanding are decisive factors for the quality of the final surface.
Substrate sanding grits from-to 120 - 400
Lacquer sanding (grit) from - to 280 - 400
Finishing Overcoatability: can be recoated after sufficient drying and intermediate sanding using the likes of COOL-COLOR HB 65285-(colour tone) or HYDRO-PU RESISTCOLOR HDB 54345-(colour tone). Can also be coated with commonly used HYDRO, PU or CN coloured lacquers and with most standard paints. (Test coat required!)
Yield per coat 7 - 14 m²/l

The spreading rate is heavily dependent on the type of application. The specifications relate to a liter of ready-for-use product, if necessary including hardener and thinner.
Working Temperature Range 18 - 22 °C
Storage temperature 10 - 30 °C
conditions of transport 10 - 30 °C
Processing instructions Add hardener slowly whilst stirring. Adjust the spray viscosity with water if required. Maximum additive volume 5 %. The hardener must always be added before thinning! Never store product mixed with hardener in closed containers. Subsequent coating: after sufficient drying and sanding back, if required, apply another coat of the same product or suitable HYDRO or PU products. Clean tools with water. For removal of dried lacquer residues use Hesse HYDRO Cleaning agent HV 6917. In case of combined coatings (HYDRO- and solvent based lacquers) rinse application tools with Hesse HYDRO Reversing agent HV 6904. When directly coating cleaned or sanded foils, please apply a test coat to check the bonding!
Particular instructions “A risk assessment was undertaken according to Directive 2014/90/EU, Annex II, Section 3. This coating does not pose a physical risk to health nor a risk to the environment when cured and dried.”
General instructions on workmanship With MDF coatings, you can avoid painting faults and edge breaks if you observe the following: Selection of a suitable MDF quality for the area of application, see manufacturer data on EU standard EN 622-5, pt. 4 Test method EN 317 (requirements on thickness swelling). Ideal panel moisture 5 - 7 %. If possible coat the MDF all around, the backs should at least receive a clear coating. Avoid sharp edges and cutaways, round-off wherever possible. Coat edges and cutaways 2x with primers, do not sand through, if need be, prime again. Thick boards that have been created by gluing together several thinner boards are, due to the variance in tension, susceptible to edge ridging. It is better to select a single MDF board of the appropriate thickness. Panels that have been glued together should always be sanded flat at the edges and colourlessly pre-insulated. Any water introduced by gluing must be allowed to evaporate prior to coating. Store primer-coated surfaces in an air conditioned location and apply the final coat in a timely manner.When working with HYDRO materials, parts that come into contact with the material must be made from stainless steel. The moisture content should be between 8 - 12 %. Do not apply or dry HYDRO lacquers at material or room temperatures below 18 °C. The ideal humidity for application lies between 55 and 65 %. During the lacquering process, a humidity level that is too low leads to surface defects (such as shrink cracks, etc.). Excessive humidity during the drying phase may drastically lengthen the drying time! In order to avoid adhesion problems, please sand the lacquered surfaces freshly before coating and apply lacquer to the sanded surfaces as soon as possible. When applied to foils, etc., please use a sample coating on the respective substrate to check the adhesion! The ideal complete hardening of lacquered surfaces that have been flashed off is reached at temperatures over 20 °C up to no more than 40 °C. Adequate, draft-free air exchange must be assured. The complete hardening of the lacquer will be reached after one week of proper storage (at least 20 °C room temperature). Woods containing large amounts of natural oils, such as teak, can negatively influence adhesion under certain circumstances. Water-soluble wood ingredients such those in ash and tannins in woods such as oak may cause colour changes and discolourations in the coating. We recommend that you always conduct a sample lacquering to evaluate the colour effect, adhesion and drying process under real conditions!
