Acronal^®  ECO 7806: Low-odor polymer cementitious waterproof coatings, bringing the industry to the next level

Odor-neutral environmental protection is an important direction for the upgrade and high-quality development of waterproof materials. Polymer cementitious waterproof coatings are widely applied in wet indoor areas. Low-odor waterproof materials are vital for the health of workers and the indoor environment.

During the application process, when liquid and powder components are mixed, traditional polymer emulsions often release significant amounts of ammonia under alkaline conditions. Ammonia is a basic substance that strongly irritates the skin, particularly the mucous membranes of the mouth, nose, and upper respiratory tract.

To reduce the ongoing harm to the health of workers and the surrounding environment, Acronal^® ECO 7806, is formulated with a unique polymer composition and production process. Not only is the polymer itself low in odor, Free from harmful substances like formaldehyde and ammonia, but it also releases no ammonia when mixed with cementitious powders (click on the video below for the experiment). This truly achieves low-odor environment.

Cementitious waterproof coatings are widely used in areas like kitchens, bathrooms, and balconies, which are constantly exposed to moisture. The coatings are essential to maintain sufficient flexibility to cover micro-cracks under prolonged water exposure, ensuring long-term waterproof performance.

• Acronal^® ECO 7806, through the unique polymerization technology, endowed the waterproof film with outstanding initial flexibility—high tensile strength and elongation.
• After immersion in water, the strength retention rate and elongation far exceed standard requirements (refer to GB/T 23445-2009 Type II and III), enabling the waterproof materials to meet the diverse demands across different seasons and regions amidst varying conditions.

To meet the renovation needs of both new and existing buildings, polymer cementitious waterproof coatings are formulated into different grades according to the GB/T 23445-2009 standard, catering to various application scenarios.

To address the need for flexible formulations, Acronal^® ECO 7806 can be formulated with varying liquid-to-powder ratios (1:1.5 or 1:2.2) to meet the strength and elongation requirements of Type II and III. Additionally, BASF offers corresponding formulation solutions based on Acronal^® ECO 7806 for different regional cement powders, enabling you to upgrade your polymer cementitious waterproofing product lines quickly and provide a low-odor environment.
