                        Drying time (25 )

                                Table dry 5min

                                Hard work 1h

          Pipeline drying time (steel preheating 50 , bake temperature 120 ) 5min

          Painting interval

          Minimum coating interval of 8h or more, before painting with a cloth dipped in 107 thinner wipe 704 paint film surface to determine whether the complete curing. If the zinc powder dissolved in the cloth, indicating that the film has not yet fully cured, to continue to dry; at less than 70% relative humidity, the film can be sprinkled on the water to make the film curing; dry cloth to colorless Dissolved), that the film has been cured completely before painting the next road.

          The maximum coating interval is unlimited, but the zinc salt must be removed before overcoating.

          Can use the time (A, B mixed)

          Available time24h12h6h

           It is recommended to coat the number of channels without air spray 1, dry film thickness 20m.

          After supporting paint with chlorinated rubber, epoxy, epoxy asphalt, asphalt, polyurethane, ethylene and other systems supporting the use of coatings. But not with oily, alkyd, polyester paint used in supporting.

          Surface treatment Steel sandblasting to Sa2.5, surface roughness 30-75m

          Construction conditions Construction can be carried out at -20 C to 50 C

                               • When the temperature of the substrate is too high (40 ), spray gun must be used, but the temperature of the substrate should not exceed 60 . In order to avoid dry spray must be adjusted to 107 thinner dry spray so far

                                • Substrate temperature should be above 3 above dew point

                                Relative humidity not more than 85%

          Coating method

          Airless spray

                     Diluent 107 Diluent

                     Dilution 0-10% (by weight of the paint) * Note to prevent dry spray

                     Nozzle diameter 0.4-0.5mm

                     The discharge pressure was 15 MPa (about 150 kg / cm2)

            Air spraying

                         Diluent 107 Diluent

                         Dilution 0-10% (by weight of the paint) * Note to prevent dry spray

                         The nozzle diameter is 2.0-2.5mm

                         Air pressure 0.3-0.6MPa (about 3-6kg)

          Roller / brush Large area coating is not recommended, can only be used for small area repair

                               Diluent 107 Diluent

                               Dilution 0-5% (by weight of paint)

          Cleaner 107 Diluent

          For safety measures, please refer to the Material Safety Data Sheet (MSDS) of Anhui Kailin New Material Co., Ltd. (formerly Tianchang Kailin Chemical Co., Ltd.).

          Packing Group A (zinc paste) 20L barrels 20kg

                        B component (main agent) 10L barrels 10kg

          Shelf life of 6 months

          Notes During the construction of the mixer stir constantly to prevent zinc powder precipitation

                                When the temperature is above 30 , it is necessary to prevent the dry spray from adding 0-10% of the 107 diluent

                                704 inorganic zinc primer for the longest painting interval time is not restricted, but in the paint under the road before the paint must be completely removed from the zinc surface of the paint film formed, otherwise it will affect the film adhesion and protective effect of the interlayer

          Remark For the correct use of our products, please carefully read the "User's Guide" in this manual.

          Statement The above data and data are based on our test and practical experience in the use of accumulated and can be used as construction guide.
