NERO GUARNIZIONI
Silicone rubber
01ANERO1204
It is often necessary to join irregularly-shaped components or parts made from differing materials and it is hard to find sealants which adapt to requirements for shape and thickness. The silicone adhesive Nero Guarnizioni is a ready-to-use universal high-performance mono-component paste: it is resistant to oil, petrol and refrigerants. Exposed to the humidity in the air, it polymerises at room temperature, forming a resistant and flexible rubber. It does not drip even when applied to downward-facing or vertical joints. Easy to apply on a wide range of temperatures; it remains flexible from -70°C to +250°C. It adheres to the majority of surfaces, including clean metals, glass, wood, ceramics, silicone resins, vulcanised rubber, natural and synthetic fibres and many plastics and painted surfaces. Resistant to weather, vibrations, humidity, ozone and extreme temperatures; it has a good level of thermal stability and excellent electrical insulation and water-proofing properties.For perfect adhesion, clean the surfaces thoroughly before applying the product.
All surfaces must be perfectly clean and grease-free. All of the surfaces except those in plastic and wood must then be rinsed with a rapidly-evaporating degreasing solvent such as acetone or alcohol; rubber surfaces must be roughened with emery paper and then cleaned with a solvent. The adhesive/sealant is to be applied evenly to the prepared surface; the sealant should be finished with a spatula within 5 - 10 minutes after application, before a skin forms. When used between two surfaces, position the second surface, applying sufficient pressure to eliminate air but not to move the sealant; the glued object should be left at room temperature. Actual polymerising times are according to relative humidity, level of restriction and the thickness of the sealant. Apply the sealant, forcing it into the joint in order to ensure total contact between sealant and surface; non-polymerised sealant can be removed with an acetone-soaked cloth. If excess sealant is polymerised, it can be removed with a knife or scraper.
