Adhesion
Strong, lasting bond to a wide range of flexible and rigid substrates, without pre-treatment in most applications.
Chemical resistance
Withstands exposure to solvents, cleaning agents and everyday chemicals without degrading the printed pattern.
Mechanical resistance
High resistance to abrasion, scratching and flexing, ensuring durability throughout the product’s lifecycle.

Fast polymerization
Rapid UV curing supports high-speed production lines with minimal drying time and no solvent evaporation step.
High resolution
Sharp, well-defined fine features, enabling detailed patterns and small-scale functional designs.
Finish quality
Smooth, uniform surface finish with consistent gloss and appearance across the printed area.
Storage & shelf life
Store in a cool, dry place away from direct light and heat sources. Reseal the container promptly after each use to preserve viscosity and curing performance.
Process recommandation
UV curing is compatible with standard UV-LED or mercury lamp systems. Curing dose and line speed should be adjusted to substrate, ink film thickness and geometry.
Pipettes
Designed for high-precision applications, our micro and nano-deposition pipettes print line widths from 1 µm down to 0.5 µm, with consistent, contamination-free results thanks to a single-use design.

FAQ
How do I choose the right pipette?
The choice depends on the line width you need to print. Quartz pipettes, from 300 nm to 700 nm, cover the finest range; glass pipettes, from 1.5 µm up to 50 µm, extend that range up to 80 µm line width. If you are unsure, tell us about your project, and we will help you select the right pipette.
Can I use my own ink?
Yes. HPCaP is compatible with a range of third-party inks, including PVP, polymer, UV resist, metal-organic decomposition (MOD), and quantum dot inks, in addition to Hummink’s silver and gold inks. Printability cannot be guaranteed with other inks. Contact us to check the compatibility of your ink.
What’s the minimum order quantity?
Our pipettes are sold in boxes of 10 (MOQ: 1 box).
How should I store the inks?
Store between 4–8°C, and minimize exposure to air once opened. Under proper storage, our inks have a shelf life of 6 months from production.
What is the recommended sintering temperature for our Ag ink?
The recommended sintering temperature for Hummink silver ink is 190 – 220 °C, with a minimum sintering time of 20 minutes. The required duration may vary depending on the characteristics of the printed pattern, particularly its dimensions and thickness. Larger or thicker structures may require longer sintering times to ensure proper sintering and achieve optimal electrical conductivity
How do I fill a pipette with ink?
The pipette can be filled with a syringe. Filling cones, available with our patented CentrifugInk, make filling easier. The CentrifugInk then fills the pipette all the way to the tip and avoids air bubbles.
