abstract
This specification covers the testing and material properties of water-dispersed protective roof coatings composed of water-based acrylic latex elastic emulsion polymers, where a variety of pigments and other additives are added to provide the desired physical properties. The manufactured product shall be in liquid form and may be applied to the roof surface by brushing, scraping, rolling or spraying. Its application guide is not discussed here. The coating must be tested and meet the liquid characteristics required for solid viscosity, volume and weight. Conversely, the film should also conform to the physical properties of drying as follows: initial elongation at break; Initial tensile strength under maximum stress; The final elongation at break after accelerated weathering; Through; Edema; Adhesion force; Fungal resistance; Tear resistance; And low temperature flexibility after accelerated weathering.
