RT8609 Styrene Acrylic Latex Binder
RT8609 is also a rigid acrylic waterproof emulsion with excellent color retention and weather resistance. It was developed by Celotech Ruico manufacturers to meet the requirements for the manufacture of rigid cement-based waterproof coatings.
- Without plasticizers and APEO.
- Excellent compatibility with cement.
- Good adhesion, strength, water resistance, and alkali resistance.
- Meets the waterproofing requirements for basements, kitchens, bathrooms, and other areas.

Practical Application Value in Construction Coatings
While many construction coatings appear normal during the initial application phase, they are prone to developing the following issues after prolonged exposure to sunlight and rain:
- Whitening of the paint film
- Chalking and dusting
- Loss of surface gloss
- Alkali efflorescence from the substrate
- Reduced coating adhesion
RT8609 is specifically engineered with a focus on outdoor durability; it addresses these issues through a stable polymer structure and is particularly well-suited for:
- Exterior wall areas subject to long-term exposure
- Humid environments
- Highly alkaline cement substrates
- Construction scenarios characterized by significant temperature fluctuations

FAQ About RT8609 Styrene Acrylic Latex Binder
The shelf life of RT8609 is one year from the date of its initial use.
The RT8609 coating emulsion can be protected from microbial erosion during transportation and storage in its original unopened packaging. To prevent microbial erosion during processing and in open packaging, hygiene should be maintained when using it. In some cases, it is recommended to add a bactericide appropriately to avoid problems caused by microorganisms.
To assist customers in meeting their own requirements for product handling, safety, and disposal, as well as to comply with applicable local health and safety regulations. Celotech Ruico will provide Safety Data Sheets, which will be updated regularly. Therefore, before handling or using any product, please request and review the latest SDS. If you have any other questions, please contact your Celotech Ruico contact person.
It won’t affect its construction performance; instead, it will enhance it. During the construction process, it will be more smooth and stable.
It means that the coating it forms is characterized by “high strength and low deformation,” prioritizing resistance to water pressure and structural stability rather than tensile deformation.
Flexible systems are better able to stretch and “bridge cracks,” whereas RT8609 places greater emphasis on “structural density” and resistance to hydrostatic pressure.
Basements are constantly exposed to damp or even pressurized water environments; they require a combination of “impermeability + alkali resistance + structural stability”—areas where rigid systems hold a distinct advantage.
