Elastic latex paint is a latex paint whose paint film has an elastic function. The so-called "elasticity" means that the paint film maintains good flexibility, elongation and resilience in a wide temperature range, so it has good crack bridging ability. As a latex paint, it has the physical and chemical properties and decorative properties of ordinary paints.
The use of elastic latex paint has the following two.
(1) Wall paint
Its function is to cover the cracks on the wall, so it has a better effect of decorating and protecting buildings than ordinary latex paint. Cement mortar wall surface, due to its inherent characteristics, shrinks in volume during hardening, resulting in voids and tiny cracks at the interface between cement and sand. Under the action of temperature, humidity, freeze-thaw, and external forces, the voids and tiny cracks grow and connect. cracks visible to the naked eye. The ingress of moisture can accelerate and worsen the condition . Although the coating film of ordinary paint has a certain degree of flexibility, it can also withstand the expansion and contraction displacement related to the usual thermal conditions , but they cannot resist the development of cracks, that is to say, when cracks appear on the concrete wall, the coating The layers will also crack together, presenting a problem affecting its protective and decorative functions. The application of elastic latex paint has just solved this problem satisfactorily.
(2) Roof waterproof coating
The elastic latex paint with excellent tensile strength, elongation at break, bonding strength and impermeability is applied alone or compounded with carcass reinforcement materials on the roof and the surface of the substrate that needs to be waterproofed to form a continuous coating. , Seamless, integral , and a certain thickness of coating film, which plays the role of waterproof and impervious.
