The Scientific Side of Permanent Markers

The Scientific Side

For a lot of professionals who use permanent markers or “Sharpie,” one of the biggest questions is how this thing works. Why are these permanent markers staying permanently? The science behind this technological marvel, usually overlooked, involves three main ingredients: resin, carrier, and colorant. With the right combinations, these ingredients make “Sharpie” or permanent marker work.


While its definition sounds pretty obvious, it is not. Usually, these markers need to meet two qualifications to be considered as a permanent marker: it needs to use pigments or dyes, and it needs to adhere to all surfaces, as well as water-resistant.

According to experts, writing using this device can be expected to last at least three to four months, and several years at most. Although people might use this every day, there is a big chance that people are hard-pressed to explain how it works. This device contains common ingredients that make up regular markers.

These components dictate how the device interact to deliver a clean and reliable line. Always remember that its lasting effect is usually a misnomer as most devices labeled as everlasting are not light-fast unless it is marked explicitly by manufacturers as archival markers.

What do these things consist of?

These pens are hallowed plastic tubes that are airtight, with a single opening at its tip. These tubes encase a long stick of sponge-like and porous material, which sticks slightly out of its opening (also called the tip). The absorbent material inside is saturated with permanent ink as it drains or evaporates from the exposed tip. Its siphoning effect will draw the fluid from the inside, out of its tip. The ink is composed of three ingredients: resin, solvent, and colorant.


Colorants are pigments or dyes that give these fluids its unique color. Whether pink, yellow, neon, red, blue, black, or any other hue, colorants is what we see when we look at lines made by the device. The main difference between pigments and dyes is that pigments are usually water-insoluble or a non-polar solvent, while dyes are water-soluble.

The pigment is a non-polar solvent unless it is ground to very fine dust. Because of the powder’s property, they are usually the favored colorant choice for these devices, given their resistance to humidity dissolution and other environmental agents.


This is the key to making an excellent broad, felt-tip pens; without the solvent to transport and dissolve colorant, as well as the ink resin through the small sponge, these pens will not work. Although water is a polar solvent, these solvents need to be non-polar to break down resins and colorants, which are usually non-polar.

Traditionally, manufacturers use xylene, but because of health hazards, they switched to lesser toxic component like isopropanol and ethanol, since children are starting to use these items for school-related activities. Once the liquid ink us applied to the surface, solvents automatically evaporate, leaving only the resin and colorant.


These are glue-like polymer. Inks made of resin make sure that the colorant sticks to the surface once the it evaporates. If the ink is only made of solvent and colorant, the colorant will turn to powder and fall on the surface as soon as the solvent component evaporated or dried. While ink made of this component is naturally very sticky, the solvent will keep it fluid and free inside the sealed plastic tube.


The difference between non-permanent and permanent market rest on its resin component; broad, felt-tip pen has resins that non-polar. It does not dissolve in water. That is why, if the ink with a non-polar component gets on a surface, it will stay there permanently. But if you use chemicals like acetone, a non-polar solvent, instead of water, it will dissolve the resin and remove the mark.

On the other hand, non-permanent ones use ink made with resin that is water-soluble or readily dissolves in water. Not only that, but permanent markers may also use specific dyes and pigments that are not water-soluble or do not dissolve easily in water.


While removing these ink sounds like very contradicting, there are ways to remove it. Non-solvent chemicals like acetone, as well as alcohol, will remove it from both porous and non-porous materials. A lot of household items like hair spray or deodorant contain alcohol and can be used to remove these inks.

How To Choose a Commercial Printer Maintenance Contract

Commercial Printer

While choosing the right kind of commercial printer for your business can affect efficiency and advertising success, deciding how to maintain the device can be just as vital. These printers are typically larger than personal units, have a high-volume printing capacity and may include additional features, such as the ability to scan and copy documents. If you have decided that the repair and maintenance of your office printers are best handled by a servicing company, there are a few factors you might consider before you choose a contract.

Consider the Number of Printers You Own 

If you run a small business, then you may only have one or two printers that manage all of your print media jobs. However, a repair and maintenance contract may still benefit you, especially when you consider how a printer breakdown could affect your employee’s productivity. If you own a larger business and use a variety of different printers, then you may want to choose a company that offers flexible contracts and can customize them according to your needs.

Read Reviews 

Taking the time to read printer repair and maintenance company reviews online may help you avoid overspending or wasting time contacting businesses that cannot meet your requirements. For example, if you need printer service Washington DC, you can browse reviews to gauge whether you are in a specific service area, what other companies have experienced and whether the company you choose can service your printer brand.

Gauge Repair Vs. Contract Costs 

Before you agree to a printer repair contract, you may want to review the cost of individual repair jobs versus the cost of an annual service contract. If you find that your printers need maintenance or repairs more than a few times per year, then you may want to invest in a service agreement.

When business printers break down, it can impact productivity. Having an affordable and flexible service contract in place may help you avoid extended downtime and the cost of emergency repair visits.

Essential Metals in the Automotive Industry


It’s no secret that many various metals are involved in manufacturing auto parts. Less commonly known, though, is which specific metals are used the most and for what reasons. Whether it’s for mechanical strength, resistance to damage, weight, low costs or ease of manufacturing, there are particular metals and alloys that the industry has come to rely on.

Steel and Iron

Easy to work, inexpensive, readily available and reliably strong, steel is a staple in automobiles. The chassis and body panels of a vehicle, as well as many wheels, are frequently made of steel, not only for durability but also for flexibility—steel bends or dents under impact, absorbing kinetic energy well without breaking, which is a vital safety feature in cars and trucks. Some steel alloys have key traits besides mechanical strength that make them valuable; stainless steel, for instance, makes for corrosion-resistant bolts and exhaust pipes.

Iron is less common in modern models, usually outclassed by steel or other alloys. However, iron can be cast more readily than steel, making it useful for complex parts that need high dimensional stability.


Most people think of metal foil or cans when they think of aluminum, so it might surprise you to know that aluminum alloys can boast strength on par with steel. On top of that, aluminum is significantly lighter than steel, and surface treatments can make it corrosion resistant. Though working aluminum has historically been more expensive, modern advances in metalworking allow aluminum die castings to be used for a variety of auto parts, making its use more common nowadays. Still, economically speaking, aluminum remains a high-end material for many purposes.


Titanium is considered a premium metal in the automotive industry. While it’s prohibitively expensive to work with, limiting it to high-end models, it possesses an unparalleled strength-to-density ratio along with high stiffness, corrosion and oxidation resistance and consistent performance across a wide temperature range. Luxury sports cars make use of titanium to boost toughness and remain lightweight.

The prized materials in the automotive industry have changed over time as advances in technology-enabled more economic manufacturing. As metalworking practices continue to evolve, alloys that are costly now may see wider usage in the future.…
