Shading coatings are generally divided into black glue, colored glue and silver glue. In terms of sun protection ability, vinyl >: colored glue > silver glue, but coated umbrellas should not be used in rainy days as far as possible, and the coating is easy to fall off. In the choice of umbrella color, dark color has better sunscreen effect than light color.

Vinyl umbrella is characterized by enhanced anti-ultraviolet ability, no odor and no aging, while silver umbrella relies on coating to prevent ultraviolet rays. The quality of coating directly determines the degree of ultraviolet protection. Most of the silver umbrellas on the market are nominally UV-proof and easy to age.

Matters needing attention in using sun umbrella

1, it is necessary to pay attention to the corrosive effect of rain on the sunscreen coating. In order to maintain the sun protection performance of the sun umbrella, it must be used separately from the umbrella. If the umbrella surface is dirty, you can gently scrub it with a soft brush dipped in clear water. Don't rub it by hand or too often, otherwise it will also affect the sunscreen effect.

2. If you want to maintain the parasol and extend the service time, it is best to use the parasol and umbrella separately.

3, the sun umbrella can't stop the rain, because the rain contains a lot of impurities such as sulfide. If the sunscreen paint outside the sun umbrella is often washed by rain, it will gradually fade and its anti-ultraviolet function will be weakened.
