Styrofan^®  ECO 7577: Revolutionizing waterproofing technology with ready to use, super durability, and near-zero VOC

The quality of construction materials is often summarized as "30% material, 70% operation," because the performance of construction materials heavily depends on the contractor's understanding of the material, their experience, habits, and on-site handling ability. On the other hand, the factors affecting construction quality are varied, making quality control difficult and disputes hard to resolve. Therefore, in addition to professional training and project supervision, the development of new material technologies to reduce variable factors is also an important measure to improve project quality.

Typically, waterproofing materials under tiles use reliable cement-based waterproofing coatings, which require specific liquid-to-powder ratios, on-site mixing, and must be used within a specified time. Deviations in these steps can affect construction quality. BASF's Styrofan^®  ECO 7577 polymer dispersion adopts advanced polymerization technology, specifically for single-component mastic waterproof coatings, meeting the strict performance requirements for waterproofing beneath tiles. It requires no mixing, is ready to use right out of the can, has no time limits for use, reducing variable factors during application, making it simple and convenient.

Waterproofing beneath tiles is a concealed process that needs to prevent base layer cracking and water seepage, ensuring that subsequent tile installations do not lead to hollowing or detachment. The quality of this process is crucial for the future use of the building. According to industry standard JC/T 2415-2017 (liquid applied water impermeable products for use beneath ceramic tiling bonded with adhesives), there are very specific requirements for waterproof coatings in terms of crack resistance, adhesion, and durability.

The single-component mastic waterproof coating formulated with Styrofan^®  ECO 7577 is a highly flexible material with excellent crack-bridging capabilities. Even when the base layer has relatively wide cracks, there is no risk of leakage. Due to its special cross-linking structure, Styrofan^® ECO 7577 inherently possesses high adhesion and cohesion, and the embedded hydrolysis-resistant molecular chain design gives the waterproof coating superior water resistance and adhesion after alkali treatment, ensuring the long-term durability of the waterproof coating.

In building renovations, especially refurbishment projects, the environmental performance of materials not only directly relates to the on-site environment and the health of construction workers but also significantly affects the indoor environment and comfort of the occupants after quick move-in. As people pursue a higher quality of life and as scientific understanding of materials and detection methods improve, the environmental standards and requirements for materials have become more specific
