The roof is the outer protective structure at the top of a building, typically serving to withstand external factors such as wind and sun exposure, ensuring the building's durability and sturdiness. Protective measures during roof construction are indispensable. Today, Feiyang introduces the application of polyaspartic polyurea in roof waterproofing.
Traditional roof waterproofing materials commonly include modified bituminous felt, waterproofing membranes, APP modified bitumen, polymer waterproofing rolls, and JS waterproofing paint. Traditional roof waterproofing materials, such as bitumen, waterproofing rolls, and APP, when exposed to sunlight, undergo photoaging which can result in warping and cracking. Even if the material itself doesn't warp or crack, it can still fracture due to the warping and cracking of the concrete (caused by stress, vibration, and other factors). Waterproofing rolls, in particular, have numerous seams, which, under the effects of outdoor photoaging, can accelerate leakage. Once leaks occur, pinpointing the exact location becomes challenging.
Polyaspartic polyurea surpasses traditional waterproofing materials in performance. It possesses excellent physicochemical properties, including high tensile and impact strength, flexibility, wear resistance, anti-slip properties, anti-aging, and corrosion resistance. Moreover, the polyaspartic polyurea coating adheres 100% to the substrate, offering a seamless surface with superior integrity and effective leakage prevention.
Due to its inherent flexibility, anti-aging properties, and mechanical strength, elastic polyaspartic polyurea remains unbroken even when concrete warps or cracks. Not only does it remain intact, but it also firmly "grips" the concrete, providing both waterproofing and protection. This elastic polyaspartic polyurea waterproofing material is especially suitable for high-end building structures' roof waterproofing, achieving a "once and for all" solution.
Feiyang has been specializing in the production of raw materials for polyaspartic coatings for 30 years and can provide polyaspartic resins, hardeners and coating formulations. Some of our polyaspartic coating formulations: Polyaspartic Coating
