طلاء واقٍ أكريليكي.

Vetotop AC440 is a single-component elastomeric pigmented coating, ready for immediate site use. Vetotop AC440 is an elastomeric, water-based protective coating based on a special acrylic polymer. It provides excellent elongation and recovery, low dirt pick-up, resistance to aggressive elements, UV light, and rain. It is available in a wide range of colors.

الاستخدامات

  • To protect atmospherically exposed reinforced concrete structures from attack by acid gases, chloride ions, oxygen, and water, and where there is a danger of subsequent cracks appearing within the substrate.
  • Suitable to protect all types of structures, cementitious substrates, masonry, and aggressive marine and coastal environments.

المزايا

  • Highly elastomeric coating with excellent elongation and recovery properties which are maintained at subzero temperatures.
  • Excellent barrier to carbon dioxide, chloride ions, oxygen, and water. 
  • UV-resistant. 
  • Water-based. 
  • Wide range of decorative colors.

تعليمات الاستخدام

All surfaces should be dry and free from contamination, such as oil, grease, loose particles, decayed matter, moss, algal growth, laitance, and all traces of mold release oils and curing compounds. This is best achieved by light grit blasting the surface. Where moss, algae, or similar growths have occurred, treatment with a proprietary biocide should be carried out after the grit-blasting process. Where application over existing sound coatings is required, conduct trials to ensure compatibility and retention of the bond between the underlying coating and the substrate. It is essential to produce an unbroken coating of Vetotop AC440. To ensure this, surfaces containing blowholes or similar pitting areas should first be filled using Vetorep CR523, a cementitious fairing coat. Allow Vetorep CR523 to cure for approximately 48 hours, dependent on ambient conditions, before applying Vetotop AC440.

To obtain the protective properties of the Vetotop AC440, it is important to observe the correct rates of application and over-coating times.

The application should not commence if the temperature of the substrate is below 5°C. 

Mask any areas of glass. Protect plants, grass, joint sealants, asphalt, and bitumen-painted areas during application. Apply Vetoprime AP443 in one or more coats until the recommended application rate of 0.7 m2/liter/coat @50 microns thickness.. This is best accomplished by using portable spray equipment. If in doubt about the condition of the substrate, contact the Saveto Technical Center consultation. 

Allow the primer to dry for a minimum of 8 hours (at 20°C), longer at lower temperatures. Under no circumstances should the primer be overcoated with Vetotop AC440 until the surface is properly dry.

Vetotop AC440 may be applied by the use of suitable brushes or rollers. Refer to Saveto Technical Department for queries relating to spray application before the commencement of work. 

Treat all primed substrates with two coats of Vetotop AC440. Stir the material thoroughly before use. Apply the first coat to all areas using suitable brushes or rollers to achieve a uniform coating with a wet film thickness of fewer than 400 microns. Allow this coat should to dry before continuing.

Apply the second coat of Vetotop AC440 exactly as detailed above. Under poor drying conditions at low temperatures, it may be more practical to apply three thinner coats (270 microns wet film thickness each) of Vetotop AC440 to achieve better ‘through drying. This method will achieve the correct recommended dry film thickness.

Remove Vetorep CR523 and Vetotop AC440 from tools and equipment with clean water immediately after use. Remove Vetoprime AP443 from tools and equipment using Vetonit Solvent XX400.
