SOLVENT BASED ACRYLIC EXTERIOR COATING SYSTEMS

(TERAKORD 301 -TERAKORD 302)
Why Solvent Based Acrylic Exterior Cladding System?
We can collect the advantages of exterior cladding made with solvent-based acrylic siding systems in six main groups.
1.   Excellent adhesion to mineral and metal surfaces
In conventional systems, the particle size of the binder resin is expressed at the micron level, while the particle size of the binder resin in the solvent acrylic system is expressed in the angstrom order. Therefore, even the smallest capillary pores are easily penetrated. Thanks to this feature, it is impossible to see a solvent-based acrylic exterior cladding system that peels off or spills from the wall.
2.   Min. surface preparation (surface tolerance)
Lime used in conventional plaster systems creates an alkaline structure that classical paint systems do not like. The very high alkali resistance of the solvent-based acrylic system does not prevent color changes etc. that may be caused by the alkaline environment on such surfaces. eliminates negative effects.
3.  Opportunity to apply regardless of climatic conditions
Film formation in solvent-based acrylic systems is based on solvent evaporation. While curing continues over time in other systems and the film layer is constantly stretched, this is not seen in the solvent-based acrylic system. It is possible to apply in a wide temperature range with the solvent acrylic system. It creates the possibility of application on damp surfaces in very cold or very hot weather. Therefore, it ensures timely fulfillment of commitments and cost savings. Unlike water-based systems. 15 min from the rain. In previous applications, the film is not affected by water at all.
4.   High acid and alkali resistance
Solvent-based acrylic system; It shows excellent chemical resistance against the problems arising from the alkaline structure of concrete, carbon dioxide and sulfur dioxide gases, and acid rain. One of the most important points is the protective effect of the solvent-based acrylic system on the iron reinforcement. A rusty iron occupies 2.5 times more volume than a non-rusty iron. This creates a huge internal pressure, causing plaster cracks and flaking. According to carbon dioxide diffusion gas permeability measurements, 120 mic. A dry film-thick solvent-based acrylic siding is equivalent to the protection of a one meter thick concrete mass.
5.   Breathing  feature
Depending on the bonding resin structure and the properties of the selected functional fillings, the moisture inside the wall is provided to escape. While the water vapor pressure caused by the humidity inside the wall in sunny weather affects the removal of the stretched film layer in conventional systems, this negative effect is eliminated thanks to the breathing feature of the solvent-based acrylic system.
6.   Self Cleaning Factor
In the solvent acrylic system, immediately after the application, the binding layer is the surface covering layer. However, over time (1 -1.5 years later) erosion occurs in this layer. This erosion is negligible considering the thickness of the paint film. Therefore, self-cleaning continues by constantly renewing itself after 1-1.5 years thanks to the new layers coming out from the bottom.
