Must-see! Do a good job of water-like industrial paint winter coating skills have been organized for you!

Winter is coming, with the temperature drop, the temperature difference between day and night becomes bigger, which has a great impact on the construction of paint. Non-drying, hanging and other ills are common problems in autumn and winter paint construction, which bothers many construction teams.
Have "environmental protection", "fashion" temperament, water-based paint once listed to become the darling of the paint industry, by the end-user favorite, but because of the "proud", "high cold" personality, water-based paint construction process often need a hundred care, a little careless will appear coating accident . Coupled with the coming of winter, the construction of water-like paint is facing a huge test.
below for summing up the experience and lessons of water-based paint winter coating, after a lot of detailed theoretical exploration and practical research, brought water-based paint winter painting "six-step" note analysis, to help you easily play winter coating.
step1 substrate treatment - "three degrees"
cleanliness: oil removal, rust removal must be carried out before coating to reduce paint film defects (ideal rust removal grade: injection cleaning Sa21/2 levels) roughness: smooth, dense surface to be treated to the appropriate roughness substrate temperature control at 10 to 50 degrees C is appropriate;
International common surface treatment standard comparison
Step2: water paint deployment - "good water"
can only use pure water or drink tap water can not use hard water, salt water, acidic water, moldy water can not add oily thinner, otherwise there will be particles, holes and other issues;
Step3: Construction viscosity - "high point good"
water-based industrial paint viscosity should be higher than the same type of oily products water-based paint atomization process thinner volatilization than paint less, if the viscosity is low easy to produce flow hanging ideal construction viscosity range: 20 to 70s (4 cups) water-based paint is mostly non-Newtonian fluid (shearing and reducing adhesion), medium and high viscosity under easy to construct;
Step4: coating equipment - "to be dedicated"
water-based paint coating can use oil spray gun, but before use to thoroughly clean the residual solvents and coatings in the spray gun and paint all lines and metal parts in contact with water-based paint are required to use stainless steel electrostitive spraying, water-based paint generally does not need to be adjusted, but spraying equipment (spray gun, pump) need to be replaced with water-specific equipment;
Step 5: Coating Kit - "Look Recommended"Metals White blank surface must be coated with primer or primer in one paint, not direct construction paint water-coated paint coating film thickness should not be too high, otherwise easy to hang and affect dryness recommended dry film thickness of each road: finish is not greater than 40 sm The primer is not greater than 60 sm recommended thin coating multiple channels can be used "oil base and water surface" matching, but large-scale coating before the need to verify adhesion is not recommended "water base and oil surface", especially in a single group of water-based primer construction paint;
Step6: Coating drying - "controlling temperature and humidity"increase the temperature control. , dehumidification equipment, to ensure that the coating environment temperature is not less than 10 degrees C, humidity is not higher than 75% if the optimal construction window (temperature: 20 to 35 degrees C, humidity: 45 to 70%) coating, the coating effect is better;
After the above "six steps" careful care, water-based industrial paint "high-cool miss" seconds become "soft green cute", showing "fashion", "environmental protection" temperament at the same time, coating effect also captured the hearts of more users.
about the winter coating summary - only the construction environment is controlled, the coating process is reasonable, in order to do a good job of water-based paint winter coating!
