Is it better for a sun umbrella to have a coating or not? What is the coating of a sun umbrella?

In order to avoid getting tanned in the summer, I finally made up my mind to buy a sun umbrella. However, after looking for a long time, I found that all sun umbrellas are coated. Are the current sun umbrellas with coatings better? Are sun umbrellas better with or without coating? What is the coating on a sun umbrella?

Is it better to have a sun umbrella with coating or without coating?

For uncoated umbrellas, it depends on whether they are sun protection umbrellas. Some umbrellas are uncoated but can provide sun protection. Umbrellas like these have to go through layers of processing before they can be manufactured, so they will be more expensive. In general, an umbrella without coating is not a sun protection umbrella and it cannot provide sun protection.

What is the coating of the sun umbrella?

The reason why sun umbrellas have sun protection effects is that a layer of coating is added on them. Let's take a look at the various coatings:

1. Ordinary silver glue: The earliest and most basic anti-ultraviolet fabric is brushed on general fabrics to play a role in sun protection. The disadvantage is that the silver glue on the umbrella surface is easy to fall off and the sun protection effect is general. UPF>30%

2. Ultra-fine encrypted silver glue: It is an upgraded version of ordinary silver glue, and the silver glue is not easy to fall off. UPF>35%

3. Pearl glue: brushed on the umbrella surface, it will shine silver in the sun, general sun protection, easy to fall off, UPF>30%

4. Double-sided silver glue: It can be called - the peerless duo. Such as the Snow, Moon, Wind and Flower of the Paradise Umbrella, with zero light transmittance, 100% UV protection, and 41% cooling effect. The most representative umbrella among the Paradise Umbrellas with super strong UV protection function. UPF=100%

5. Double-sided colored glue: inner silver glue, the umbrella surface is made of colored glue with advanced technology and bright colors. Not easy to fall off. They are the new generation of peerless duo. UPF=100%

6. Black glue: The umbrella surface may be leopard print or colorful pattern, and the inside of the umbrella is brushed with black glue, which has better sun protection function than silver glue. UPF>50%

7. Crystal glue: ultra-thin fabric, super UV protection, looks like natural marble. No fading. UPF>99%

8. Titanium metal color glue: imported fabric. It is the most advanced sun-protection fabric in the world. It is ultra-thin, environmentally friendly and 99% UV-proof. The cooling effect is very good. The umbrella surface is woven from encrypted molecules and has a strong water-repellent function. The umbrella surface is titanium metal color, bright and dazzling, and looks noble. UPF>99%.

9. Transparent coating: Glue-free umbrellas are made by injecting a transparent sunscreen coating into the PG umbrella cloth. It does not affect the high appearance of the umbrella cloth, and has a water-repellent effect. It can be used in both sunny and rainy days. Most of them are European and American brands.

What kind of coating is good for sun umbrellas?

The darkest coatings provide the best protection from the sun. Coated parasols use a glue layer to block the light source and thus block ultraviolet rays. Compared with the outer coating of the umbrella, the inner coating of the umbrella will have a longer lifespan. Good parasols have double-sided coating, and the coating is also divided into black glue, silver glue and colored glue. Silver glue parasols use inexpensive and high-quality sunshade cloth. Is black glue or silver glue better for parasols? We know that silver glue is placed on the inner side of the parasol and can block direct ultraviolet rays. Silver glue is cheaper than black glue, but its disadvantage is that it is easy to fall off and it is easy to crack after long-term exposure to the sun.

Can a sun umbrella protect against UV rays without coating?

Whether a sun umbrella can block ultraviolet rays or not, the texture of the fabric is not the most important thing. The main thing is what kind of technical processing the manufacturer has done on the fabric. Generally speaking, cotton and linen fabrics have certain UV protection properties, but the degree is not strong. In the past two years, most of the sun protection umbrellas sold on the market were coated with a layer of silver glue on the umbrella surface. This treatment can reflect and block some direct ultraviolet rays. However, the quality of silver glue varies. The silver glue of sun umbrellas produced by manufacturers with good technical conditions is not easy to fall off, while some cheap sun umbrellas are just coated with a layer of silver on the umbrella surface in order to make up the number, and the color fades after being exposed to sunlight several times.
