Precautions
· Before use, pour into the group A, or according to the required ratio of deployment, with how much with the number, mix well after use, and within 6 hours after the preparation of finished
• Tools used during construction must be dry and clean
· The surface to be painted must be clean, no water, no acid and alkali
· It is strictly forbidden to contact with water, acid, alkali and alcohol during the process of paint and coating. Component B can easily react with water, alcohol, etc., with paint after the remaining part of Group B must be tightly sealed barrels, so as to avoid moisture caused by cement loss
In order to make the A and B components fully cross-linked and cured completely, with paint after 25 ℃ in the temperature curing 30min before painting. Temperature below 25 ℃ can be appropriate to extend the aging time
· The paint is not subject to the longest painting interval limit, completely cured without sandpaper to be able to fight the second finish painting
· Construction and drying The relative humidity during solidification shall not be more than 75%, otherwise it will cause serious film blistering
· When the temperature is below 0 ℃, the curing reaction is stopped, so it is not suitable for outdoor construction
· This product must be cured after coating 7 days before delivery
