IMAZ™is a range of resin panels with encapsulated materials ready to suit a variety of applications. Select from our IMAZ™product range or create your own combination using our interlayers, adding color, depth, gauge, surface finish, resin or propose us your own material for encapsulation. Chemical Resistance IMAZ™ shows a good resistance to a number of chemicals. The overall chemical resistance is however dependent upon the following parameters: ■ temperature (resistance decreases with higher temperatures) ■ stress level (best resistance is with flat sheet, clamped in a frame) ■ chemical concentration...

Fabricating 1 GENERAL General Guidelines IMAZ™ sheet can be worked with most tools used for machining wood or metal. Tool speeds should be such that the sheet does not melt from frictional heat. In general, the highest speed at which overheating of the tool or plastic does not occur will give the best results. It is important to keep cutting tools sharp at all times. Hard, wearresistant tools with greater cutting clearances than those used for cutting metal are suggested. High-speed or carbon-tipped tools are efficient for long runs and provide accuracy and uniformity of finish. Since plastics...

Routing is especially recommended for trimming work pieces. Always use routers of at least 750 Watts, and a speed of 18.000 to 25.000 rpm is preferred. Bits should be straight fluted preferably two-fluted, carbide-tipped, or high-speed steel, with a diameter of 4 to 12 mm. Always feed counter rotation-wise up to 1,5 m/min, and cool with compressed air only. Drills designed for plastics are recommended, but standard twist drills for metal will do the job as long as they have not been used on metals before, though they require slower speeds and feed rates to produce a clean hole. For deep holes,...

Forming (REFER ONLY FOR IMAZ FORM SHEETS) This is only general guideline as the find result depends always from the encapsulated material. Cold curving IMAZ™ can be cold curved with a minimum radius of 175 times the gauge thickness for outdoor applications, and 125 times the thickness for indoor applications. When smaller radii are needed thermoforming is the solution. There is no need to pre dry IMAZ™ sheet. Only very old thick sheet could have absorbed so much moisture as to make pre drying (at 60°C) desirable. IMAZ™ sheet can be thermoformed at low temperature (110-155°C). Sheet temperatures...

Bonding and fastening 1 SOLVENT BONDING Use extreme caution when working with solvents: they may be toxic or contain carcinogens. Adequate ventilation is essential. Obtain Safety Data Sheets from the solvent manufacturer. This technique has been used for years to make displays from acrylic sheet, but can also be used to construct threedimensional shapes with IMAZ™ sheet. To bond small pieces, one can use a hypodermic needle and making sure that the solvent flows throughout the area to be cemented. Edge dipping is another method used to assemble two flat parts under a 90° angle. The edge of the...

When working with adhesives, the usual safety and health precautions should be taken and eventual special instructions from the adhesive manufacturer should be observed. A lot of commercial adhesives have proven their effectiveness for bonding IMAZ™ (to IMAZ™ or other materials). Adhesives on polyurethane or acrylic (toughened) basis give good results. Take into account that stresses in the sheet or parts in combination with solvents or adhesives may cause cracking. Cut and finish the surfaces to be bonded carefully. A good alternative is a 2 component polyurethane adhesive, which exists in a...

The best way to fasten IMAZ™ is to use screws with a cylindrical head. Never use screws with chamfered heads. They cause stress cracking. Drill holes 0.5 mm larger than the screw. Screws of plastic can always be used. When using metal screws or bolts, use plastic washers (nylon). Metal thumbscrews can be used without washers. Use galvanised types only. Never use glue to tighten bolts. No more than 2 extra twists after turning firm by hand. Mechanical fastening will produce a stronger part than solvent bonded parts and allows for easier disassembly and cleaning. 6 WELDING While mechanical fastening...

The sheet edges can be sanded using both wet and dry systems. Dry sanding can result in gumming as frictional heat build-up is created. Wet sanding gives a smooth finish. In both cases, further finishing in order to restore the gloss will be necessary. Example: start with 80-grit paper and end with 400 or 600-grit. 2 POLISHING Polishing is a time consuming activity and should only be applied for smaller series and parts made out of thick gauge sheet. The edges can be polished by different techniques. Keep in mind the specific colour of IMAZ™: a glass clear edge will rarely be achieved. Mechanical...

Cleaning IMAZ™ sheet may be cleaned by using a clean soft sponge and washing with lukewarm water containing a mild soap or a slightly acidic, neutral or slightly alkaline detergent. Then rinse thoroughly with clean water and dry with a chamois leather or a moist sponge. A subsequent anti-static treatment is recommended. Fresh paint splashes, grease, smeared glazing compounds, etc. can be removed before drying by rubbing lightly with isopropyl alcohol on a soft cloth followed by a thorough wash and rinse as described above. Rust stains can be removed with a 10% oxalic acid solution. Do not use...
