Coppi

Coppi  is a single-component polyurethane foam in an aerosol. Its special formula, characterised by a low level of subsequent expansion of the foam, long open times, a compact cellular structure and high resistance to tears, make it ideal for gluing roof tiles. The long open times guarantee excellent adhesion on both sides of the tile while the low level of subsequent expansion of the foam prevents undesired raising of the tiles and waste of material due to sideways seepage. The high resistance to tears guarantees excellent  sealing of the assembled materials over time. The hardened foam may be cut, holed, sanded, painted and plastered. It adheres firmly to wood, concrete, tile, asbestos cement, metal, glass and various plastics with the exception of polyethylene, Teflon and silicon. It also has high resistance to water, detergents, microorganisms and chemical agents. Fire reaction class: B2 as per DIN 4102-1. The special formulation of Coppi makes it very suitable for bonding applications, but at the same time Coppi reduces its suitability for applications where more attention is paid to the speed of curing and the volume obtained. For these applications we recommend the use of Window & Door or C 2.0.

Instructions for use

1. The surfaces must be free of oil, grease and dust. If necessary wet the surface before application to guarantee that the fresh foam has the humidity required to form a uniform cellular structure.
2. Remove the aerosol protection cover and screw it to the extruder gun required (T2000 or T500 type by Torggler Srl) or, in case of manual dispenser, insert the extension nozzle to the dispenser and screw the latter to the valve.
3. Shake the aerosol for at least 15 seconds before use and repeat this operation if you stop working at any stage.
4. Turn the aerosol upside-down so that the valve is facing down, point the gun / extension nozzle as required as required and press the dispenser with your fingers. The amount of foam required to fill the cavity depends on the subsequent expansion of the foam. Under normal conditions (23 °C and 50% R.H.), the foam increases its initial volume by about 10–20%.
5. After hardening, any excess may be cut away with a knife or sanded off using sandpaper.
6. If you do not use the entire contents of an aerosol, stand it upright and press the dispenser briefly. The gas jet produced will clean the valve and the gun / extension nozzle.

Cleaning 
Clean any traces of non-hardened foam (e.g. on clothing, doors, etc.) using Cleaner for polyurethane foams. Hardened foam must be removed mechanically only (e.g. scraped off or sanded).

Observations
The yield of the foam is highly dependent on the temperatures of both the aerosol and the surface. At low temperatures, both the pressure at which the fresh material comes out and the yield of hardened foam are reduced considerably. For easy extrusion of the material and a high yield, use at an aerosol temperature of 20 °C.

Storage

Store in an upright position in a fresh area. Do NOT store in a horizontal position as this would lead to the rapid formation of encrustations beneath the valve, which would compromise the extrusion of the foam definitively. Coppi remains stable for at least 18 months if stored in an upright position in a fresh and dry area (at temperatures below 25 °C). Respect the expiry date indicated on the cylinder.

Warnings

The Coppi aerosol is a pressurised container. Keep away from sunlight adn do not expose to temperatures above 50 °C. Do not puncture or burn even when empty. Do not spray on a naked flame or an incandescent element. Store at a distance from any source of combustion. Do not smoke. Keep out of the reach of children. . Highly flammable. Harmful if inhaled. Contains diphenylmethane –4,4’, diisocyanate (EEC no. 615-005-00-9). Can irritate the eyes, airways and skin. Can cause an allergic reaction if inhaled or if it comes into contact with the skin. Keep away from sources of ignition. Do not inhale aerosol content. In the event of contact with the eyes rinse immediately with lots of running water and consult a doctor. In the event of contact with the skin wash with lots of running water and soap. Wear suitable protective clothing and gloves. In the event of insufficient ventilation, use appropriate breathing apparatus. In the event of an accident or malaise, consult a doctor immediately (if possible, showing him the label).
