Alcohol resistant PP non treatment silk screen printing ink

  Mainly used for ABS, hips, as, PVC, PC, PPC, PMMA, acrylic Untreated PP (polypropylene), partially untreated or treated PE (polyethylene), pet, PBT, PA / PA66 nylon, OPP film, BOPP film or sheet, LDPE (low density polyethylene), HDPE Screen printing or pad printing of other commonly used engineering plastic products such as (high density polyethylene)
Product characteristics: bright light, high hiding power, excellent adhesion, bright color, saturation and alcohol resistance

Performance test:
1
100 grid test: 1mm * 1mm * 100 grid 3M 600 adhesive tape peeling without color fading

2
Alcohol resistance test: 500 g / 5cm2 load 99% industrial alcohol absorbent cotton, 500 times back and forth, no change

Safety standard: tested by European standard EN-71 part3, American Standard ASTM f963-11 and EU ROHS environmental protection standard

Usage:
1
Diluent can be A-05 solvent of our company

2
Curing agent: you can choose to add 10% of 106 curing agent of our company to increase adhesion and improve ink film hardness, but it will affect ink color difference or slow down ink drying speed
The use time of the ink with curing agent is 4 ~ 6 hours
The higher the ambient temperature, the shorter the use time, and the remaining ink can not be recycled

3
Ink preparation: if it is necessary to add curing agent, add curing agent first, stir and stand for 5 minutes, then add diluent, fully stir and stand for 5 minutes

4
Our special S-300 slow drying paste can be added to prevent printing ink film from blurring, wire drawing or screen plugging

5
Rubber scraper: PU polyurethane; Hardness: 70 ~ 80 degrees is appropriate, and the ink scraping angle is 60 ~ 70 degrees * *

6
Screen selection: 100 ~ 420 mesh is suitable for printing (about 30 square meters can be printed with 300 mesh screen per kilogram of ink)

7
Wipe off grease / dust and other impurities on the surface of the substrate before printing

8
If the screen is blocked, it can be cleaned with 718 screen washing water, and then printed after the screen solvent volatilizes

9
Drying: dry the surface for 5-10 minutes at room temperature, after 24 hours of solid drying, or bake at 80 ℃ for 30 minutes, and cool after printing for 3 hours (the specific drying time depends on the local seasonal temperature)

Precautions:
1
The materials have different printability to the ink
It is recommended to make mass production after small batch trial printing

2
For multi-color overprint, the next color shall be printed after the surface is dry

3
The adhesion performance shall be tested after the ink film is completely dry

4
Pay attention to the temperature and humidity of the printing place: excessive humidity will affect the adhesion; If the humidity is too low, it will be easy to wire drawing; High temperature is easy to block the network

5
The ink must be sealed
During storage, it is strictly prohibited to contact open fire or high temperature, and placed in a cool place

6
It is not recommended to put the unused ink back into the undiluted ink to prevent color difference and other defects
