In this modern age, every single thing we use is changing. The effect of technology is everywhere but the only difference is some changes can be observed but some cannot be observed. One classic example of a thing wherein we cannot sense the advancement is wall paints.
The painting and coating industry is a very huge industry in itself and it puts in a substantial amount of money in research and development. Thus, there are a lot of advancements which happened in recent times. Today, there are a variety of interior and exterior paints available ranging from Antibacterial paints to temperature-sensitive paints.
So, let us have a look at these news types of paints and the science & technology behind these paints.
Let me tell you that there are 4.5 million species of bacterial and fungal species in the world and these tiny things are everywhere around you and are always ready to make you unhealthy. In the right conditions, microbes can double every 30 minutes.
A typical wall is a very good place for bacteria and fungus to grow. That is why you need to be careful and make a smart choice while painting your walls. To solve this problem, paint manufacturers have come up with Anti-bacterial paints.
These paints inhibit the growth of bacteria by stopping their reproduction process.
Coming to the science behind it, these paints have some active anti-bacterial agents like activated silver. Materials like silver give out some ions which interfere with the reproduction process of bacteria and inhibit it. This is called activated Silver Ion technology if silver is the anti-bacterial agent.
2.Odour Eliminating Paints
There are a lot of organic compounds especially aldehydes which give bad smell and are commonly produced inside living areas from fabrics like carpets.
To solve this problem, a lot of paint brands have made revolutionary formulas to make paints that can reduce common interior odour. One such technology is called Activated Carbon Technology wherein the activated carbon absorbs these organic compounds in air and tries to keep the room fresh for a longer time.
Sounds great, isn’t it?
Basically, the activated carbon encourages a popular chemical process called adsorption which pulls in fine particulates into its pores and locks down pollutants and bad-smelling chemicals most importantly formaldehyde.
3.Heat Sensitive Paints
Heat sensitive paint is a type of paint that changes colors depending on the temperature of surroundings. This property of materials is called Thermochromism. These paints have thermochromic pigments that are sensitive to heat.
After absorbing a specific amount of light or heat, the crystalline or molecular structure of these pigments reversibly changes in a way that they now absorb and emit light at a different wavelength than at a lower temperature. So, that is how these paints work.
Though these types of paints do not have practical applications in painting your house, you can think of using it to give a creative look and to amaze people in some places in your house.
A classic example where this paint is used is in baby bottles which change color when the temperature goes above the safety limit.
4.Fire Retardant Paints and Coatings
Fire retardant paints have the ability to inhibit fire. There are a lot of fire accidents every year which causes a lot of deaths. Keeping this in mind brands have come up with fire retardant paints. There are two broad forms in these types of paint.
In this type, the heat generated due to fire causes the materials to swell and form an insulation layer.
2.Combustion Retardant Type
In this type, the chemicals in the paint fuse together due to the heat and stop combustion. An example of such chemicals used in these paints is chlorinated paraffin or chlorinated rubber.
5. Washable Paints
Paints loose shine and get stains as time passes. It becomes pretty difficult to keep walls clean especially in houses with children who love painting on walls.
Everyone wants there walls to look brand news for a long time and that is why a lot of brands are coming up with special types of paints that are highly washable.
These emulsions have some special cross-linking polymers and fine pigments which makes it easy for us to wipe out stains from the walls.
6. Dry Erase Paints
Today, everyone needs a big whiteboard. So, the idea of converting a wall into a whiteboard sounds awesome, right?
A new type of paint called dry erase paint allows you to convert any wall/surface keeping the same background & color to a write-erase surface.
These paints come in two cans and you need to mix an equal amount of paints from two cans before painting any wall.
So, those were 6 different types of paints which we wanted you to know. Some of these paints are crazy, aren’t they?
Tell us which type of paint surprised you and made you think “Does this type of paint exists??” Do you know about any other crazy type of paint? Let us know in the comments. Let us also know which type of paint you are going to try out.
