                99-956B alkali-soluble anti-etching

                This series of matte blue printing ink, has the characteristics of high viscosity and thixotropic thick thick, can produce very clear circuit board products.
                It can be widely used in industrial circuit boards and the like.
                This acid resistance of corrosion inhibitors:
                1, provides a high degree of print resolution.
                2, the ability of anti-such as ferric chloride, ammonium persulfate, copper chloride etchant.
                3, to provide the greatest degree of precision replicas and strong force.
                4, can be removed by an alkaline solution of sodium hydroxide.
                5, the ignition point: 40 ℃.
                6, the storage period: in the case of a closed container for up to two years (@ 25 ℃).
                7, viscosity: 25000mpa.s (NDJ-1 viscometer, spindle No. 4, rotation speed of 12 revolutions per minute at 25 ℃)
                Instructions:
                1, screen: Use the direct and indirect film version of stainless steel, polyester or nylon monofilaments dimension can, as to how to select the appropriate screen and mesh, they should according to the desired effect or printing inks the heap thick set, when you need to print fine lines, use solvent-resistance film is formed with a single silk-dimensional version of the stainless steel, mesh 270-300 (100-110 thread / cm) or 120 filaments / cm of polyester network.
                2, peel: containing 2% -4% sodium hydroxide solution, dip or spray on the circuit board can be stripped ink, in addition to other common chlorinated solvents can; use strong high-pressure water wash plate after etching the remaining liquid.
                3, Printing: careful and stir or diluted before use, using a durometer polyurethane rubber scraper were 65-75 when printing.
                4. Dilution: Under normal circumstances is not diluted, but when you want to add a volatile solvent printing and adjust the correct ink viscosity, you can use SSI 2000 thinner for dilution, the maximum dosage of 5%.
                5. Drying: at room temperature for about 60 minutes to dry the need, but according to the circumstances surrounding the stack thickness and the ink may be, please note, not over 90 degrees Celsius, 10 minutes, in the infrared drying machine, as long as a minutes to dry, but to root
                 According to the apparatus of the kind of light bulbs, light size, and distance.
                Precautions:
                1) Stir before use to avoid moisture absorption.
                2), since the plastic surface characteristics are not the same, before use do sample testing to determine the quality.
                3) according to standard health regulations and safety regulations to use this product, there should be no harm to the human body, but as other general chemicals, the use of this product should also try to avoid skin and eye are contaminated, if they splash and should be based on a large number of Rinse, and treatment.
                4), indicating that this technical information and data within the company through many years of research engineers and believed to be accurate, but it does not mean that when the ink use can get the same effect, because this information is based on technical engineers test environment was developed , so when using the ink, should be workshops and operating conditions, after the actual test print and determine whether the customer fit.
