2. Main ingredients: special acrylic copolymer;

 

3. Property; water solubility, pH 8.0 ~ 8.5, non-ionic;

 

4. This product pays attention to environmental protection, does not contain any plasticizing ingredients, and has the fastness of oily ink. It is suitable for PVC, leatherette, combed nylon fabric. It can be used for down clothing, windbreaker, assault clothing, umbrella cloth, sunscreen, canvas, combed fabric, etc. it has good covering power, good effect, strong fastness, washable, non irritating smell, and good surface gloss after printing;

 

5. Storage period: 8 months at room temperature (sealed state) without adding other raw materials (such as crosslinking agent and color paste).

 

3、 Operation precautions: use parameters

 

1. Scope of application: manual block printing, flat screen and round screen machine printing. Recommended use: 150 mesh to 180 mesh wire mesh;

 

2. It is recommended to use: 150 mesh to 180 mesh wire mesh; oil scraper, 65 ° - 75 ° flat scraper;

 

3. This product is not easy to plug the net. It can be printed directly. It is a two-component product. 2% catalyst (No;

 

4. If the printing is not overheated, it needs to be dried naturally for 48 hours. Recommended overheating method: after printing and natural drying, bake 80 ℃ (the reverse side of the printed fabric) do not overheat the front side of the pattern to prevent blistering. 3-5 minutes to achieve the best results;

 

5. Before production of large goods, we must first test the small sample to make the small sample as the standard.

The water-based ink is usually alkaline (mainly maintained by amines). If the pH value of the water-based ink is too high, it will affect the drying speed of the ink; if the pH value is too low, the drying speed will be faster, but it is easy to reduce the solubility of the ink, block the printing plate, and cause the problem of dirty layout. Amine will volatilize continuously in the printing process, and pH value will drop continuously. In order to maintain the stability of printing, it is generally necessary to monitor the change of pH value in the printing process in time. When pH value drops below 8.5, it is better to supplement amine auxiliaries in time for adjustment. A better way is to directly add amine additives to the diluent of ink, so as to maintain the stability of pH value.
