In daily life and work, signature pens are indispensable writing tools. However, ordinary signature pens are easy to smudge or disappear after contacting water, which brings troubles to many written contents that need to be preserved for a long time. The emergence of waterproof fineliner pens has solved this problem well. Even if the handwriting is soaked in water or wet by rain, it is still clearly visible. So, what is unique about waterproof fineliner pens? How is it waterproof? This article will discuss in detail the composition and working principle of waterproof fineliner pens.
1. Working principle of waterproof fineliner pens
The reason why waterproof fineliner pens are waterproof mainly depends on the following scientific principles:
1.1 Hydrophobicity of ink components
The main components of oil-based inks and pigment-based inks have hydrophobic properties and are insoluble in water. Therefore, even if water contacts the paper, it cannot dissolve the ink and keep it intact.
1.2 Physical adhesion of pigment particles
The tiny particles in pigment-based inks will be tightly adsorbed on the paper fibers, and will not be easily peeled off even if water flows. This adhesion ensures the water resistance of the handwriting.
1.3 Curing and penetration mechanism
Oil-based ink will penetrate deep into the paper after writing, and solidify as the solvent evaporates, thereby improving water resistance. In contrast, water-based pigment-based ink mainly relies on the curing of the ink surface to form a protective layer.
2. The core components of waterproof fineliner pens
The waterproof performance of waterproof fineliner pens mainly depends on the composition of the ink. The waterproof inks on the market are mainly divided into the following types:
2.1 Oil-based ink (oil-based ink)
Oil-based ink uses oily solvents as carriers, such as mineral oil, vegetable oil or synthetic oil. Its characteristics are:
It has extremely strong waterproof properties, and water cannot dissolve oil-based ink;
After writing, the ink penetrates the paper fibers and is not easy to erase;
The drying speed is moderate, but long-term storage may cause the pen tip to clog.
2.2 Pigment-based ink
Pigment-based ink uses water-insoluble micro-pigment as a colorant. Unlike water-based dye ink, its characteristics include:
The pigment particles in the ink adhere to the surface of the paper to form solid text or patterns;
It has strong water resistance and will not fade or dissolve even if soaked in water;
It has good light resistance and antioxidant ability, suitable for long-term archival documents or works of art.
2.3 Gel ink (neutral ink)
Gel ink usually uses water-based or oil-based solvents, combined with pigment particles or resin components to provide good waterproofness. Its characteristics include:
It writes smoothly and is suitable for daily office or signature.
Compared with traditional water-based ink, it has a certain degree of waterproofness, but not as strong as oil-based or pure pigment-based ink;
Suitable for users with high writing needs, but does not require extreme waterproofness.
Different types of ink determine the application scenarios and performance of waterproof fineliner pens. Therefore, choosing a suitable pen depends on specific usage needs.
3. Use and maintenance of waterproof fineliner pens
In order to extend the service life of waterproof fineliner pens, the following measures are recommended:
3.1 Avoid long periods of non-use
Oil-based inks and pigment-based inks tend to dry and solidify at the pen tip, so the pen cap should be tightly closed when not used frequently to prevent the ink from clogging the pen tip.
3.2 Store in a suitable environment
Avoid storing waterproof fineliner pens in high temperatures or humid environments to prevent the ink components from deteriorating or the solvent from volatilizing.
3.3 Choose a suitable writing angle
Maintaining a 45°~60° angle between the pen tip and the paper surface can reduce pen tip wear and ensure that the ink is released evenly and smoothly.
The core of waterproof fineliner pens is the synergistic effect of pigment-based inks, oil-based solvents, adhesives and curing agents. These ingredients together construct a water-resistant, quick-drying, and highly adhesive ink system that allows the handwriting to remain intact after contact with water.
Whether in office, art, outdoor, or medical fields, waterproof fineliner pens provide strong stability and safety.
