1 Metals have had a fascinating effect on people since time immemorial. Throughout history, man has always tried to make better use of various metals. Today, it is impossible to imagine our lives without metal. But a further step is the development of polyurethane decorative metal. This product line is highly versatile and suitable for many substrate materials. At the time of application, the mixture of components has a metal content of 80%. This results in a surface consisting almost entirely of metal. This enables forms to be easily created that would not be possible with solid metal, or which would only be possible with a high level of complexity. Currently, polyurethane decorative metal surfaces can be realised with copper, bronze, brass, zinc and iron. Polyurethane decorative metal is made up of three components: 1. PU decorative metal base DE PU decorative metal hardener DR PU decorative metal powder ZD 3136 copper ZD 3137 bronze ZD 3138 brass ZD 3151 zinc ZD 2690 iron Mixing the components: Gravimetric mixing On account of the different specific weights, the mixing ratios are determined gravimetrically and vary depending on the metal powder. Mixing polyurethane decorative metal with copper, bronze, brass, iron, and zinc powder PU decorative metal base DE g PU decorative metal hardener DR g PU decorative metal powder 80.0g g Mixing instructions Step 1: Mix PU decorative metal base DE in the specified mixing ratio with the PU decorative metal hardener DR Step 2: Add the selected PU decorative metal powder ZD 31 and stir intensively with the base mixture until the mixture is smooth and free from lumps.

2 Use: Substrate and pre-treatment of the substrate A wide variety of substrates are suitable, e.g. MDF sheets or laminated chipboard, pre-treated with a polyurethane primer. Sand substrate materials beforehand, P Application Depending on the desired effect, application is possible using a cup gun, brushing, dappling, etc. For smooth, glossy metal effects: Spray application with gravity flow cup use a cup sieve with For antique and textured effects: Spray application with gravity flow cup and subsequent texturing by hand (dappling, etc.). Brushing; after drying, application of polyurethane coloured lacquers or pastes possible to emphasise the hollows, for example. Parameters for using gravity flow cups on horizontal components Addition of 5-10% PU decorative metal thinner DV 4966 Nozzle size mm Spray pressure 2-3 bar Application quantity Apply g/m² in multiple spray coats Parameters for using gravity flow cups on 3D components Addition of 5-10% PU decorative metal thinner DV 4966 Addition of 0,3-0,5 % PUR Thix-Paste ZD 3596 Nozzle size mm Spray pressure 2-3 bar Application quantity Apply g/m² in multiple spray coats Drying At least 1 day at 20 C room temperature.

3 Sanding/polishing: Sanding apparatus Orbital sander, 5 mm stroke, with integrated dust extraction (M) Graduated surface sanding Textured surfaces starting with grain 150 or 180 (734 U), then with 280, 400 (334 U), 600, 800, 1000 (260 L), finally with 1000, 3000 (Trizact) Smooth surfaces, starting with grain 280, 400 (334 U), 600, 800, 1000 (260 L), finally with 1000, 3000 (Trizact) Polishing the surface Hand polishing device with felt pad or polishing bonnet + metal polish (from Unipol, Bauerrichter BRS 05, Mirka metal polish UF3); polish again with a clean felt pad/polishing bonnet. Cleaning the surface Remove oxidation with a micro fibre cloth, e.g. Premium 2022 polishing cloth (3M) a specialist cleaner, e.g. Perfect- IT III control spray, or, if applicable, stainless steel cleaner & polish (3M). Another good alternative is our product DH Care and protection of the surface: Caring for the surface Apply care product, such as the high-gloss sealant Perfect-IT III (3M), Mirka Liquid Nano Wax, or Autoglym High Definition Wax, with a micro fibre cloth to protect against finger marks and tarnishing and polish. Protecting the surface Coat with Hesse PUR cellulose lacquer DE glossy, DE semi-matt mixing ratio 10: 1 with PUR hardener DR 4008 adding 30% PUR thinner DV 4900 application quantity g/m² or use the nano sealant Nanotol (from CeNano) according to its instructions for use. Important note Before repainting with polyurethane cellulose lacquer, a drying time of 2-3 days should be allowed in order to avoid changes to the effect. Usage example: Aging or oxidation effects Application: Version: /5

4 Spray application: one coat of g/m² (for data see Application) with the following mixture: 16 parts (by weight) PU decorative metal base DE parts (by weight) hardener DR parts (by weight) PU decorative metal powder ZD 2690 iron 7 parts (by weight) thinner DV 4966 see mixing instructions Dry for minutes at room temperature 20 C Brushing, dappling See mixture above, but with just 1-3% of thinner DV 4966 Dry for at least 24 hours at room temperature 20 C Graduated sanding with grain , remove sanding dust with a dry cloth Surface effect rusty iron: Apply 1x oxidation agent for Decorative Metal DZ by spraying or brush/sponge (the oxidation process becomes visible after a short period of time). The reaction time is depending on the desired effect and should be chosen accordingly. Subsequently clean the surface. or Surface effect e.g. aging effect on bronze with patina: Apply 1x Patina Aging agent for Decorative Metal DZ by spraying or brush/sponge (the oxidation process becomes visible after a short period of time). The reaction time is depending on the desired effect and should be chosen accordingly. Subsequently clean the surface. If desired, fix effect by spray application as follows: one coat of polyurethane cellulose lacquer DE mixing ratio 10: 1 DR % thinner DV 4900 Dry for at least 16 hours at room temperature 20 C Beware: if not fixed, oxidation will continue! More information for the user: Metals are subject to certain variations in colour, too. Sufficient material should therefore be ordered for an item. With subsequent deliveries, differences in colour tone are possible. Metals and metallic surfaces are subject to natural oxidation, which results in changes to the colour tone. For cleaning and care, we recommend the products listed in our presentation. Any other polishes and cleaning products may result in changes to the colour tone and effect. Special instructions: Specialist knowledge is required when selecting the item to be worked on, preparing the substrate, mixing and preparing the individual components and treating the coated areas. During the sanding it is essential to ensure a sufficient removal of sanding dust by suction. Our competent field sales team will be happy to assist you and share with you the skills needed through training. Minimum order quantity: Version: /5
