Why Polyaspartic Polyurea Surpasses Traditional Waterproofing Materials?

Progress in materials is a response to societal needs. The principle of "survival of the fittest" in nature is equally applicable in the realm of materials.

Polyaspartic polyurea 's rise to fame in the 21st century is attributed to its outstanding properties, its versatility across a broad range of applications, and its ease of application. In the industry, polyaspartic polyurea is often referred to as the "noble waterproofing coating," and its demand is soaring year by year. According to industry forecasts, in the coming years, the production of polyaspartic polyurea will far surpass that of traditional waterproofing materials, like waterproofing membranes and coatings.

The appeal of polyaspartic polyurea in the waterproofing sector began with its exceptional properties, which are gradually replacing traditional waterproofing materials. A significant reason for this shift is its long lifespan. Many waterproofing repair companies opt for polyaspartic polyurea during renovations or new projects, showcasing the cutting-edge technology and immense market value of this high-end waterproofing material.

So, what makes polyaspartic polyurea superior to traditional waterproofing materials like waterproofing membranes and coatings? Based on its independently developed series of polyurea products and on-site technical guidance, Feiyang has summarized ten reasons why polyaspartic polyurea outperforms traditional waterproofing materials:

1. Coating Performance: Polyaspartic polyurea boasts exceptional UV resistance, high elasticity, and a tensile strength that exceeds 400%. Traditional waterproofing materials can't match this. Polyaspartic polyurea remains intact without cracking or powdering, even resisting leaks caused by building settlement cracks.
2. Tensile Strength: Polyaspartic polyurea's tensile strength exceeds 10MPa, indicating its remarkable stress variation capacity. In contrast, traditional membranes have a strength of just 3MPa, and coatings offer 6MPa. This difference is a primary reason why traditional waterproof layers are prone to tearing and delamination.
3. Adhesion: Testing the bond between polyaspartic polyurea and the concrete base layer reveals an average adhesion strength of over 4MPa. Traditional waterproofing materials only achieve 2MPa. Insufficient adhesion often results in the waterproof layer detaching or forming air pockets, which are quality defects.
4. Temperature Resistance: Traditional waterproofing materials cannot be applied at temperatures below 5°C and might become brittle and crack in extreme cold. They might also soften or even melt in high heat. In contrast, polyaspartic polyurea can be used in a temperature range of -20 to 120°C, making it suitable for both extremely cold and hot environments.
5. Integrity: Polyaspartic polyurea can be applied by hand brushing, roller coating, or spraying, forming a seamless membrane. This continuity eliminates the gaps that can occur with overlapped traditional waterproofing rolls.
6. Superior Weather Resistance: Polyaspartic polyurea inherently possesses excellent weather resistance. It can be directly exposed as the outermost layer, serving as a protective layer without needing an additional protective layer, which reduces construction costs and building load.
7. Longevity: Polyaspartic polyurea has a lifespan exceeding 30 years, often referred to as the "long-lasting coating" or "luxury coating." Traditional waterproofing rolls last only 3-6 years, and coatings last 1-5 years. This difference explains the industry's growing affection for polyaspartic polyurea.
8. Safety and Environmental Protection: Traditional waterproof rolls require heat to melt, posing fire hazards and emitting harmful gases. Most coatings, except water-based ones, contain diluents or solvents with high VOCs, which are harmful, flammable, and explosive. Polyaspartic polyurea, with 100% solid content and zero VOC emissions, is safe and eco-friendly.
9. Efficiency: Traditional waterproofing requires extensive manual labor, making it slow and costly. Polyaspartic polyurea cures quickly and offers diverse application methods, significantly saving time and labor.
10. Convenience: Polyaspartic polyurea can be applied over old waterproofing layers, eliminating the need to remove the existing layer, saving time and costs associated with demolition.

Understanding these distinctions and the superior physical and chemical properties of polyurea provides clarity on why it surpasses traditional waterproofing materials.
