          Surface treatment

                        · Before the paint film must be dry

                        · Remove the dirt, dust and other dirt on the film before the film, no acid and alkali and water condensation

          Construction conditions

                        · When the temperature is below 0 ℃, it is not suitable for outdoor construction

                        • Substrate temperature should be above 3 ℃ above dew point

                        · Relative humidity less than 75%

          Coating method

          Packing Group A 20L barrel 20kg

                          Group B: 2.5L in 4L drums

          Shelf life of 12 months

          Group B for 6 months


          · 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
