∎Directions for Use

Preparation for Operation：

● Tools ：The serrated plastic board, brush, plastic barrels, 30Kg electronics, rubber gloves and cleaning tools like blade .etc

● Environmental requirements：The temperature is 5~35 C and the humidity is 35 ~ 85%RH

● Cleaning：The substrate surface must be solid, dry and be clean. Such as no dust, grease, asphalt, tar, paint, wax, rust, water repellent, curing agent,

isolating agent and film. Surface cleaning can be dealt with by removing, cutting, grinding, cleaning, blowing, and so on.

● If there are cracks on the substrate surface, first step is to fill them, and the surface should be leveled. Operation after the sealant curing more than 3mm.

●Theoretical dosage: 1.0mm thick, 1.3 Kg /㎡coating needed.

 

Operation：

●First Step

Brushing the part like corner, tubes root, then symmetrical scraping. The thickness of the coating is generally 0.5mm. (Avoid bubble). When operation,It should be considered about the size, shape and environment of the construction area.

●Second Step

Symmetrical scraping when the coating is completely solidified (about 12 hours later). The thickness of the coating should be 0.7mm, and the direction of smearing should be perpendicular to the first time. The specific operation is the same as the first step.

●Third Step

Symmetrical scraping when the coating is completely solidified (about 12 hours later). The direction of smearing should be perpendicular to the second time. The specific operation is the same as the first step.The operation times depends on the

design thickness, the overall thickness is 2.0-2.2mm

.

After application

●Protection:

If necessary,a proper protective layer can be operated on the surface of the coating.

●Tools Cleaning :

It can be soaked in toluene or xylene. It is strictly forbidden to immerse in alcohol and other alcohol solvents.If it is not used for a long time, it should be cleaned immediately with alcohol or other organic solvents. The cured glue can only be

scraped or torn off.

∎Attention of operation

● Don’t mix alcohol into the product, it will cause the product invalid. The tools with the alcohol can’t be used before cleaning well.

● Avoid contact with eyes and skin. If contact with your skin, scrub first with soap water or alcohol, then rinse with water. If contact with your eyes, rinse with plenty of water, and seek medical treatment immediately.

● It is forbidden to build on the surface of the wet substrate.

●Transportation:Avoid,damp,high temperature, isolation and rain, far away from heat, handle with care and prohibit extrusion collision.

● Tools Cleaning : It can be soaked in toluene or xylene. It is strictly forbidden to immerse in alcohol and other alcohol solvents.If it is not used for a long time, it should be cleaned immediately with alcohol or other organic solvents. The cured glue can only be scraped or torn off.

∎Transport &Storage

● Transport: Keep the sealed product away from moisture, the sun, high temperature and avoid collisions.

● Storage: Keep the sealed product into cool, dry place.

● Storage temperature: 5~25℃. Humidity: ≤50%RH.

●Cartridge and Sausage :9 month. Pail/Drum:6 month.

Notice:If the temperature is higher than 40 ℃ or the humidity is more than 80%RH, the shelf life may be shorter.
