Brief description
The DC series is an abrasion-resistant, chemically resistant, formable, two-component, double-curing screen printing ink.
Product Characteristics
DC is a two-component ink can be blister moulding, wear-resistant, chemical-resistant double curing varnish, printed on the PC surface as a protective layer, after curing the varnish layer can be through the automotive industry, a variety of skin care products, chemical testing and other conditions, the product is used in automotive interior parts, home appliances and other wide range of integration of the moulded components.
Ink Characteristics
1. Screen printing ink system that can be printed on PC material surface.
2. High-pressure blister moulding.
3. Excellent abrasion resistance and chemical resistance.
4. High-gloss, matte, metal effect can be selected.
Printing conditions
1.Before UV curing, keep DC colours away from light.
2. Avoid visible and ultraviolet light during the printing process as much as possible, and the finished product should also be placed away from light to prevent product samples from cracking during the moulding process.
3.Add curing agent into the ink and mix well, machine speed 2000 rpm for 1min.
4.The ink with hardener should be used for 6 hours at room temperature (25°).
Drying conditions
1.Finger touch drying: after the ink printing is finished, immediately enter the tunnel oven for baking, the tunnel temperature does not exceed 8 out of the product to reach finger touch drying can be.
2.Final drying: After the surface drying, the product is put on the shelf for final curing, temperature 85℃, 30min.
Moulding process
1. Before moulding, if the product has been left for more than 8 hours, it should be preheated and dried at 80℃ for 30min to prevent the subsequent moulding from generating air bubbles.
2.For PC material, the high pressure moulding temperature is between 170-185℃, the specific temperature should be adjusted according to the actual product.
Curing parameters
1. Suggested lamp source: mercury lamp UV 250 to 410nm.max.365nm
2. Curing energy: 1600 to 2000 mj/cm².
3. After curing, the product can be subsequently moulded and cut, injection moulded, etc.
Storage conditions
Unopened used time is 1 year, open ink is 6 months, need to be stored in dry, cool, ventilated (5-30 °) conditions.

SPS-AS carbon fiber squeegee for duplex drum screen printing machine
SPS-AS carbon fiber squeegee is suitable for reciprocating cylinder screen printing machine. It uses carbon fiber board and Japanese ASM anti-static solvent-resistant polyurethane rubber. The printing quality is stable and the service life is high.
GM-IO is a UV curable screen printing insulating ink with excellent adhesion, high flexibility, good printability and UV curing fast drying characteristics, suitable for blood glucose meters, keyboard circuits, membrane switches and so on.
In the process of screen printing, squeegee, screen plate, substrate material and other mutual friction, generating static electricity. When static electricity accumulates to a higher voltage difference, the edge of the pattern will produce flying ink, drawing and other bad.SPS-ASM anti-static squeegee resistance <108Ω, part of the charge through the squeegee dissipation, reduce the voltage difference, to avoid flying ink and wire drawing and other problems.
In the process of cell production, the effect of screen printing will directly affect the conversion efficiency of the cell, the core of printing is the aspect ratio of the silver paste after printing. Therefore, the screen, silver paste and squeegee must remain innovative, when writing higher screen printing requirements in just ten years, the requirements of the gate line is becoming more and more fine, has been from the initial 60um into the current 30um, or even finer; Subsequent to the replacement of the squeegee (as shown in the figure below), and now SPS-AS-SL single-sided photovoltaic carbon fibre squeegee is becoming more and more popular!
FGB-MP Glass Fibre Board Squeegee
SPS-MP-X series squeegee is a new generation of one-piece squeegee specially developed by Plet and Japan Polyurethane Chemical Company for the narrow line width printing of battery cells. Compared with the traditional sanding squeegee, it has significant effect on wet weight control, printing life and efficiency improvement, etc. Using this squeegee can achieve the purpose of cost reduction and efficiency improvement.
1. Manufactured using Japanese squeegee processing, it exhibits superior solvent and wear resistance; 2. The fiberglass board scraping glue combines the fiberglass board with scraping glue, offering the elasticity of the scraping glue and the structural support of the fiberglass board. This allows for a stable printing angle to be maintained even during extended periods, ensuring uniform ink thickness.
