| Special notes | When used as a coating material with low flame-spread characteristics complying with SOLAS 74 Reg. II-2/3, II-2/5, II-2/6 and X/3, as amended, IMO Resolution MSC.36(63)-(1994 HSC-Code) 7, IMO Resolution MSC.97(73)-(2000 HSC-Code) 7, IMO MSC/Circ. 1120, this product must only be combined with other approved and technically matching products.For MDF substrates: With MDF coatings, you can avoid painting faults and edge breaks if you observe the following: Selection of an MDF quality suitable for the field of application, see manufacturer data on EU standard EN 622-5 pt.4 Test methods 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 milling grooves, round-off wherever possible. Coat edges and milling grooves 2 x with primer, do not sand through, if need be, prime again. Thick boards that have been built 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 the gluing process must be allowed to evaporate prior to coating. Store filler-coated surfaces in an air conditioned location and apply the final coat in a timely manner.“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.” |
