HF Series Carbon Slurry
- Commodity name： HF Series Carbon Slurry
Classification:
Keywords: Squeegee | Screen | Ink
HF is a halogen-free, environmentally friendly carbon paste that offers exceptional weather resistance, high opacity, and multifunctional performance—specifically designed for demanding outdoor and industrial environments as well as high-end home appliances.
Product Features:
·Environmental specifications: Halogen-free, low-VOC, compliant with Japan’s RoHS and REACH regulations, and meeting Japanese electronic industry environmental standards;
·Weather resistance: UV-resistant, aging-resistant, acid- and alkali-resistant, and oil-stain-resistant; remains free of chalking even after prolonged outdoor use.
·High coverage: High-blackness carbon-based formulation that provides complete coverage of the base color with a thin coat and offers excellent insulating and isolating properties.
·Insulation + Conductivity Balance: The surface is dense, providing creepage and clearance protection as well as prevention of microshort circuits.
Instructions:
No diluent is required for normal printing; after stirring, the ink can be directly fed into the press.
Thinner:
No diluent is required for normal printing.
“Only in the following situations is a small addition necessary.”
·High workshop temperature, thickened paste, and difficult scraping and printing
·Ultra-fine lines; requires better leveling
·Ink return deviation, printing is not fine
Add a small amount of Special No. 8 thinner.
Screen and Squeegee:
Screen mesh: 22–26 N tension polyester mesh, mesh count: 200 mesh (200–220)
Scraper: 70°–75° medium-hard polyurethane scraper
Printing substrate:
Compatible with: PET, PC, automotive-grade composite panels, and outdoor weather-resistant plastics.
Positioning: automotive, outdoor applications, high-end home appliances, and oil- and stain-resistant, aging-resistant substrates.
Curing conditions:
150℃ 30min
Sheet resistance range: (area resistance converted from 10 µm)
20 Ω–MΩ/□
Storage method:
Store in a cool, dry, light-protected, and sealed container at 5°C to 25°C.
Unopened, original packaging:
6 months (store sealed at 5–25°C)
After opening (lid removed, diluent added):
Use up within 1–2 months.
Once the container is opened, it is prone to moisture absorption, solvent evaporation, and carbon powder settling, causing the formulation to thicken over time and resulting in unstable resistance values.

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.
