  • good sanding properties with good transparency
  • ideal as a coat for corundum basecoats for open- to closed pore coatings
The product UG 7347 is a sanding sealer, which is used as the final basecoat in the system configuration before the sanding machine is used. The basecoat is therefore ideal for preparing the subsequent top coats for sanding. This UV activated product is especially used for corundum basecoats, such as UG 7465.

Information on use

Stackable after stackable directly after UV curing
Curing Hardening by means of ultraviolet rays with mercury UV-lamps.Sufficient radiation energy must be provided. This depends primarily on the type, conditions, age and design of the lamp system, so that the optimum UV lamp settings can be implemented on the respective system, and the curing should be checked. Your Hesse representative will assist you with the determination of the necessary radiant energy.
Surface preparation gelled or sanded UV basecoats.
Substrate sanding grits from-to 150 - 180
Lacquer sanding (grit) from - to 280 - 320
Finishing For system build-up with certified products such as suitable UV lacquers.
Comments on sanding Sanding is required to achieve good adhesion to the substrate depending on the substrate’s condition. Wood substrates should be sanded at 120 - 220 grit subject to wood type. Membrane substrates and basecoats should be freshly sanded at 320 - 600 grit. Dust should be carefully removed from the substrate after sanding. Intermediate sanding should generally be omitted when the bond is established when using a primer or the gelling process.
Yield per coat 42 - 126 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.
Storage temperature 5 - 25 °C
conditions of transport frost-free - up to a maximum of 35 °C
Processing instructions Regularly check the specified application quantities. Clean rollers using suitable thinners!
General instructions on workmanship Clean lamps and reflectors on a regular basis using a soft, lint-free cloth and UV 7111.
Only touch the lamps when wearing cotton gloves. Note the lamp's operating hours and replace them as per the lamp manufacturer's recommendations. Always protect open containers from the incidence of light (cover them).
Seal containers properly after use.
Sufficient lacquer sanding and inspection of the bond within the entire structure will be required in each case. Please apply a trial coating under practical conditions!
