Use of exterior wall coating which features to be met

Durable color: exterior wall coating exposed in the hot sun and rain, the continuity of the coating color is strictly test. Organic emulsioni paint exterior wall coating are mainly made from petroleum products, in under the irradiation of ultraviolet energy, often make some pigment denaturation, yellow, faded. However, if the weather is rain for a long time, organic exterior wall coating color is difficult to resist rain water erosion, so the color lasting coating is more popular. Durability: exterior wall quantity is very large. If the durability of the coating is poor, decorate frequency will be high, the cost would be a sharp rise, affect the living and office, etc. Elastic crack resistance: usually use thick mortar screeding exterior walls, there are many places need to repair. Because of cement solidification process of the change of stress or cold or hot weather, the mortar may be craze. In addition, the old wall cracks may also be caused by loose structure. Water resistance: paint and other decoration materials for exterior wall function: water resistance. No water resistant paint soon loses water resistance. Permeability: like interior wall paint, exterior wall coating must have air permeability, even higher than interior wall coating. Pollution prevention: air pollution is more and more serious, the exposed surface of the coating will soon become dirty. Development, viscosity, surface density, static electricity dust absorption function coatings is imminent. Freeze resistance: it is very important in northern cold region. The freeze-thaw cycle will result in the crack of the coating, influence of various performance indicators. Covering power: walls have enough light, and the foundation wall usually darker color. Cover bad coating can't cover the bottom color, this will affect the appearance. In general, high refractive index type rutile titanium dioxide is the best choice. Above is fujian KeBao exterior wall coating using characteristics of bring you, hope to be able to help you.
