The core technical highlight is the addition of silicone flexible additives, which makes the coating elongation at break reach more than 30%, which can easily bridge fine cracks within 0.5mm of the base surface, avoiding coating cracking caused by temperature changes and base surface expansion and contraction; compared with ordinary acrylic emulsion, the weather-resistant silicone acrylic emulsion has 40% higher UV aging resistance, and can be used stably for 12 years in extreme temperature environments; it has excellent water resistance, which can effectively block rainwater from penetrating into the base surface and avoid wall mold and alkali return; UV-resistant additives are added to effectively delay coating fading and keep the color bright and lasting; construction is convenient, only air spray is needed to complete, adapting to a variety of exterior wall base surfaces.
The capacity of a single barrel is 5 Gallons, the recommended construction thickness of the coating is 2.5-3mm, the coating rate is about 1.4kg per square meter, and the density is 1.40g/cm³; the elongation at break is ≥30%, which can bridge base cracks within 0.5mm; the bonding strength is ≥1.2MPa; the scrub resistance is ≥12000 times; the artificial weathering resistance is ≥1000h without pulverization, cracking or discoloration; it is applicable to cement mortar, concrete, exterior wall insulation board and other base surfaces, with a base surface roughness error ≤5mm; the construction environment requires a temperature of 5℃-35℃ and humidity ≤80%; the packaging is impact-resistant plastic barrels with a sealed cover to avoid leakage.
It is mainly applicable to exterior wall scenarios with fine cracks, including old community exterior wall renovation, building exterior walls in northern areas with large temperature differences, exterior wall insulation board finishing projects, etc.; it can also be used for building exterior walls in coastal areas to resist high humidity and salt spray erosion; it is suitable for exterior wall decoration of commercial complexes and residential properties, solving the problem of coating damage caused by base cracks and prolonging the service life of exterior wall decoration.
