TECHNICAL CHARACTERISTICS

Silancolor AC Tonachino is a fibre-reinforced, acrylic-siloxane resin-based coating in water dispersion which offers the combined advantages of mineral coatings and synthetic coatings. Thanks to its special formulation, it makes substrates water-repellent and vapour-permeable and it also offers excellent protection against UV rays.

• Contains synthetic fires for good crack resistance.
• Bonds perfectly to all types of conventional render and to old, well-bonded paintwork.
• Resistant to all types of climatic conditions, aggression from smog, saltwater and sunlight and forms a hard-wearing, protective layer on substrates which resists to the rigours of time.
• Gives the substrate an attractive rustic finish and is available in a wide range of colours obtained using the ColorMap® automatic colouring system.
• Complies with the requirements of EN 15824 (“Specifications for external renders and internal plasters based on organic binders”) for internal and external use.
