[Introduction]
The active substance of ROCIMA® 361 has an anti-algae and anti-fungal effect on industrial products. ROCIMA® 361 is a liquid product that can be pumped.
ROCIMA® 361 is mainly used for exterior wall paints and plasters, but also for interior wall paints with high air humidity.

[Application range and antifungal antibacterial activity]
ROCIMA® 361 is especially suitable for the protection against fungal algae in rough outer wall coatings. Such walls are usually covered with dirt and contain various air particles, such as industrial combustion and soot produced by internal combustion engines. Dust and fertilizer, pollen and other natural objects. These grimees are usually microbial cultures that provide a relatively modest need for microbial growth.
ROCIMA® 361 provides dual protection for wall coverings and plasters. First, it prevents the coating or plaster layer from becoming a fungus and algae culture medium. Secondly, when the surface becomes wet due to rain or condensation, the active substance of the product can ooze out from the plaster and paint layers to the moisture. Face to prevent the growth of fungi and algae.
If a building is exposed to long-term moisture due to its defects, its structural defects must be compensated before successful use of the microbicide.
ROCIMA® 361 is a dry film antifungal antifungal agent. Therefore, we strongly recommend the addition of ROCIMA® GT or KATHON® LXE as an in-can preservative.
ROCIMA® 361 must be thoroughly mixed with the product to be protected and should therefore be added at the beginning of the production process.
For special applications, we recommend that you first contact our sales or technical staff.
[Usage]
The optimum amount of ROCIMA® 361 is highly dependent on the likelihood, extent, treatment requirements and general sensitivity of the film to fungal and algal growth.
Since the required antifungal antifungal agent needs to be added separately and cannot be regenerated by itself, it is important to accurately predict the degree of microbial contamination, which provides a basis for determining the optimal amount of ROCIMA® 361.
For the above reasons, the range of additions listed below is for reference only.
paint
0.5-3.0%
Stucco
0.2-2.0%
If the paint film is exposed to the atmosphere for a long period of time or requires continuous condensation or contamination, increase the amount of ROCIMA® 361 added to the recommended amount.
We recommend first estimating the amount added in the lab. Practical experiments can also be carried out if necessary.
[Use and processing]
Before using this product, please refer to the product safety data sheet and strictly follow the operating procedures.
Operators need the technology and expertise to use and process industrial chemicals.
In general, safety goggles, gloves, and protective clothing should be worn to avoid contact with the eyes and skin. In case of accidental contact with the eyes or skin, rinse immediately with plenty of warm water and receive medical attention if necessary.
