产品名称

Anode low-temperature curing varnish

The anode low-temperature curing varnish, model ed-7, is independently developed by our company according to the current electrophoretic market demand and future development direction.

Description

I.Product introduction

The anode low-temperature curing varnish, model ed-7, is independently developed by our company according to the current electrophoretic market demand and future development direction.

The ed-7 has many advantages, such as good corrosion resistance, high penetration, excellent stability and convenient storage.At the same time, the coating can be cured directly at 120 ° low temperature without pre baking, which can save about 30% energy compared with high temperature electrophoretic coating.

At the same time, the anode low temperature electrophoretic paint can be widely used in workpieces that are easy to deform and change color after high temperature baking, such as aluminum alloy, zinc alloy, die-casting iron, die-casting copper and other materials.2、 Product specifications.

e. The paint can't be knocked off

f. Resistant to washing for 72 hours without blistering, wrinkling or falling off

g. Acid resistant salt spray (CASS) single side corrosion and blistering < 4mm

2, test results

a. Hardness and dry adhesion: RT × 10min, 120 ℃× 60min, RT × 12h curing after electrophoresis, dry film thickness about 14 μ M

Test as usual

Test sample: aluminum plate

Resin number Pencil hardness Baige adhesion

Ed-7 ≥ 2H level 0

Resin number	Pencil hardness	Baige adhesion
ED-7	More than 2H	0level

b. High pressure adhesion: after electrophoresis, RT × 10min, 120 ℃× 60min, RT × 12h maintenance, dry film thickness of about 14 μ m, use high-pressure boiler with standard steam pressure gauge.Using deionized water, the conductivity is less than 10 μ s / C ㎡.Put the workpiece into the water temperature of 95-99 ℃, draw a hundred grids with a spacing of 1mm first, the workpiece to be measured is suspended in the water, can not touch the bottom of the pot and the surface of the water, the pressure is kept at 0.1MPa, the time is 2h, after taking out the workpiece, pull it with a tape with a standard adhesion of (10 ± 1) n / 25mm.Pull with minimum angle.Level 0-1 is pass requirement

Test sample: aluminum plate

Resin No. pull after high pressure adhesion for 2h

Ed-7 level 0 pass requirements

Resin number	Pull after high pressure adhesion for 2h	By request
ED-7	0level	By request

c. Impact test: after electrophoresis, RT × 10min, 120 ℃× 60min, RT × 12h curing, dry film thickness: 14 μ m, use the paint film impactor with standard diameter of 8mm steel ball, and the height of impact protrusion is 2.5mm without paint dropping as the passing requirement

Test sample: aluminum plate

Resin number impact resistance

d. Boiling water resistance: RT × 10min, 120 ℃× 60min, RT × 12h maintenance after electrophoresis, dry film thickness of about 14 μ M

Use deionized water with conductivity less than 10 μs / C ㎡and put it into water temperature of 95-99 ℃. The tested workpiece is suspended in the water and can not touch the bottom of the pot or surface for 5h. Take out the paint film of the workpiece without falling off, blistering and wrinkling

Test sample: aluminum plate

Resin No. boiling water resistant 5h

Ed-7 has no shedding, blistering and wrinkling requirements

Resin number	Boiling water resistant 5h	By request
ED-7	No peeling, blistering or wrinkling	By request

f. Washing resistance: RT × 10min, 180 ℃× 25min, RT × 12h maintenance after electrophoresis, dry film thickness of about 14 μ M

Prepare 30g / L test solution with deionized water and place the sample in the test solution at 38 ±1 ℃for 72h.Pull the adhesive tape with standard adhesive force (10 ±1) n / 25mm, and pull the adhesive tape quickly at an angle perpendicular to the surface of the paint film. It is required that the paint film does not fall off or blister.

Test sample: aluminum plate

Resin No. resistant to pull after 72 hours of washing

Ed-7 has no shedding and blistering requirements

Resin number	Resistant to pulling after 72 hours of washing	By request
ED-7	No peeling and blistering	By request

e. Acid resistant salt spray (CASS): RT × 10min, 120 ℃× 60min, RT × 12h maintenance after electrophoresis, dry film thickness of about 14 μ m, salt spray test according to GB / t10125, single side corrosion and foaming of fork < 4mm
