Sweat Barrier

What is Sweat Barrier?

Sweat Barrier, a coating agent, opens the door to a world of freedom for those who have given up on a number of accessories due to concerns about nickel (metal) allergies, and to be able to choose without worrying about the material!

Have you ever…

always feeling itchy when wearing your piercings?
see your skin turn red due to your necklace?
annoyed and impatient because of rings and watches you wear?
want to enjoy being fashion-conscious with your favorite accessories without paying attention to materials?

Sweat Barrier will make your wishes come true!

Why did we developed it?

KAGEYAMA Hitoshi, one of Japan’s leading developers of industrial coatings, has been developing coating agents for accessories for his wife, who suffers from nickel (metal) allergies, along with his main work. In 2020, he succeeded in developing Sweat Barrier, an anti-allergy fluorine coating agent.
Thus, he decided to bring Sweat Barrier to people suffering from nickel (metal) allergies* around the world.
(*According to Wikipedia, 17.1% of women and 3% of men suffer from nickel (metal) allergies.)

What have we achieved so far?

We founded Suffix Co., Ltd. to bring Sweat Barrier to all people suffering from nickel (metal) allergies.To enhance the safety of the manufacturing environment, we set up our base in Nagano Prefecture, one of the cleanest places in Japan, and as soon as we started selling our products in the Japanese EC market, they gained overwhelming support on Amazon Japan and Rakuten Market.

What is our mission?

We will fill the earth with smiles and contribute to the realization of world peace by supplying the world with a coating agent for accessories that prevents nickel (metal) allergies by allowing users to apply it themselves.

Customer’s Voices

There was no change in the appearance of either the jewel or the metal, and I had no problem leaving it on for 20 hours at a time when I was starting to sweat. It dries quickly, doesn’t have any strange smell, and is easy to use, yet works great! I’m impressed that even when I use it on a small, thin chain ring, it still feels great. (Female, 20s)
I had a collection of slightly pricey earrings with designs I really liked.I didn’t want to put a sticky coating on my expensive earrings, so I searched for a resin cover for the shaft if it was a straight design, but came across this product.I ordered it with such high hopes that it would work well for my expensive earrings, without ruining the design like resin covers and without being too thick like other coatings!
When I wear an accessory without applying any coating, the contacting part immediately got hot and itchy, and I couldn’t stand it.I was battling the itch for days after that. However, it has no problem with Sweat Barrier.I can’t wait to try it on my other beautiful earrings that remain in my room.I really thought I would never be able to wear my favorite designs again.But thanks to this product, it makes it possible! (Female, 50’s)
I regret so much and should not have given up the accessories of the past that I gave up. (Female, 30s)

Here’s how Sweat Barrier is tested by public institution:
