What technical requirements define polymer modified asphalt emulsion waterproofing leather for asphalt or bitumen modification?
Polymer modified asphalt emulsion waterproofing leather requires specific technical parameters for optimal performance. Key requirements include a minimum polymer content of 3-5% for enhanced elasticity and adhesion. The emulsion should exhibit a viscosity of 100-300 cP at 25°C to ensure proper application. Additionally, a stable particle size distribution, typically between 0.5 to 5 microns, is essential for uniform coverage. The pH level should be maintained between 6 and 8 to ensure compatibility with various substrates.
