RT8608 Styrene Acrylic Resin Emulsion for Stone Paint
RT8608 is an acrylic-styrene copolymer manufactured by Celotech Ruico. Unlike emulsions commonly used in acrylic latex paint formulations, RT8608 is specially designed as a binder for stone paint and transparent waterproof coatings.
- It exhibits excellent resistance to water whitening and alkali.
- Its superior barrier properties significantly improve waterproofing and stain resistance.
- It demonstrates excellent mechanical and chemical stability.
- It is particularly suitable for repairing localized cracks in walls.

Styrene Acrylic Latex Application
RT8608 is ideal for exterior wall stone paint, delivering strong water-whitening and alkali resistance with a dense, durable film. It helps the coating maintain adhesion, stain resistance, and weather stability, while also supporting localized crack repair on cement and concrete substrates.
For transparent waterproof coating, RT8608 offers excellent barrier performance and stable film formation. It can help build a clear protective layer with strong waterproofing and stain resistance. Hence, it suits exterior building surfaces that need both durable protection and a clean appearance.
RT8608 can be used for surface protection on outdoor wooden structures, especially in humid or tropical environments. Its good water resistance, chemical stability, and protective barrier properties help reduce moisture penetration, surface contamination, and premature coating failure.
Styrene Acrylic Resin Emulsion Package and Storage
The Celotech Ruico RT8605 should be stored in a dark, cool place at temperatures between 5°C and 35°C in tightly sealed containers and is valid for 6 months. Avoid freezing of the material! Local legislation on storage must be followed.
There are three types of packaging: 50kg plastic drums, 200kg plastic drums, and 1000kg intermediate bulk containers (IBCs).

FAQ About RT8608 Styrene Acrylic Resin Emulsion
- Due to different climates in different countries, local storage regulations must be followed.
- RT8608 may be susceptible to microbial attack after opening, so consider adding appropriate fungicides for preservation.
- Avoid contact of RT8608 with the eyes and skin.
RT8608 is suitable for the high shear forces involved in the production of real stone paint. This emulsion has excellent barrier properties and can be used for surface protection of outdoor wooden structures in tropical and humid areas, as well as for transparent waterproof latex paint for buildings, providing the waterproof layer with excellent waterproofing and stain resistance.
RT8608 is not suitable for all exterior wall substrates. It is mainly used on common building substrates such as cement mortar and concrete. When using it, ensure that the substrate is firm, dry, and free of oil stains.
It can exhibit excellent mechanical stability and calcium ion stability, as well as good mineral aggregate compatibility during manufacturing high-shear stone paint.
Yes. Styrene Acrylic Resin RT8608 is suitable for stone paint formulations containing mineral aggregates such as sand.
The dosage of RT8608 depends on the formulation design, pigment or filler content, and your coating performance requirements. You need to work out the dosage with formulation tests and real application results.
Styrene Acrylic Copolymer RT8608 demonstrates good chemical stability. Generally, it can be compatible with our thickeners, defoamers, dispersants and so on. We can work with you to test first.
