APPLICATION INSTRUCTIONS
· Thoroughly stir Component B until it is completely uniform before construction.
· Mixing Ratio: This product is a two - component package, with A:B = 1:1 (by volume).
· It is recommended to use the high - temperature and high - pressure impact mixing equipment specified by our company during construction.
· Coating Thickness: 1 - 2mm (depending on user requirements).
· Theoretical Coating Rate: 4.5㎡/GAL.
· Coating Interval: The minimum time has no limit, and the maximum should not exceed 3 hours (at 25℃ and 50% humidity).
· Unused Component A should be sealed with nitrogen for storage.
· This system is solvent - free, and it is strictly forbidden to add any diluent.
DRYING TIME
· Surface dry: ≤1min, and it can reach walking strength within 10min (at 25℃ and 50% humidity).
CONSTRUCTION CONDITIONS
· The substrate temperature during construction should be at least 3℃ higher than the dew point, and the environmental humidity should be ≤90%RH.
· When constructing in a confined space, ensure good ventilation.
PACKAGING SPECIFICATIONS

Component B: 53.348GAL/DRUM.
Customized packaging is also available according to user requirements.
STORAGE
Store in cool, dry, ventilated indoor areas at 5℃-30℃. Shelf life: 12 months.
SAFETY PRECAUTIONS
·It is strictly forbidden to have any open flames in the batching and construction site, and good ventilation should be maintained. Construction personnel must wear protective gear to avoid skin contact.
·If the paint splashes on the skin, it should be cleaned immediately with an appropriate cleaning agent or soapy water.
·If it splashes into the eyes, rinse them repeatedly with clean water, keep the eyes open, and seek medical treatment immediately.
DISCLAIMER
· The above information is compiled based on the actual tests and usage experience of our company's technical personnel and can be used as a construction guide. However, due to differences in the painting environment and supporting schemes, it is recommended that users conduct preliminary tests and trials according to their actual needs and purposes before confirming the use. Our company only guarantees the quality and stability of the product itself. When our company's technical personnel are not on the painting site, our company is only responsible for the quality of the coating product itself.
· The protective effect of any coating highly depends on the painting construction. Construction factors such as surface treatment and film thickness will directly affect the service life of the coating. When using this product, users should meet the agreed construction conditions.
