Does The Adhesive In The Center Bar Of Dymo 30299 Hurt The Jewelry？

The following are common jewelry materials and their corrosion resistance, including ceramics, artificial crystals, metals, and resin, among which metals have several subcategories. We’ll discuss each one individually. 

1. Ceramics: 

High-precision ceramics mixed with precious metal alloy powders, used in jewellery for their unique aesthetics.

 Corrosion Resistance: Excellent; resists water, neutral and acidic liquids, strong acids, chlorine, bromine, iodine, and organic compounds.

2. Artificial Crystals (e.g., Swarovski): 

Known for precise cutting, synthetic crystals shine brilliantly, adding luxury to jewellery.

Corrosion Resistance: Moderate; crystals are not typically affected by corrosion but can lose their shine over time due to surface wear.

3. Metals: 

Includes various metals used in jewellery design. Corrosion resistance varies by type:

Titanium:

Known for its anodizing property, which allows for different colors.

Corrosion Resistance: Excellent; forms a protective oxide layer, highly resistant in marine and chemical environments.

Copper:

A non-precious metal often used with PVD coatings for diversity in design.

 Corrosion Resistance: Poor; prone to corrosion in humid, acidic, or salty environments, forming green patina.

Aluminium:

Lightweight metal often used in modern jewellery designs.

 Corrosion Resistance: Good; forms a natural oxide layer, but can corrode in acidic or basic environments.

Gold:

A precious metal with timeless appeal and shine.

 Corrosion Resistance: Excellent; highly resistant to oxidation and corrosion, maintains its shine in most environments.

Silver:

Popular in jewellery for its lustrous appearance.

Corrosion Resistance: Moderate; tarnishes in air due to reaction with sulfur, forming black silver sulfide.

Tin:

Used in combination with other metals, often for coating to prevent rusting.

Corrosion Resistance: Good; performs well in dry environments, but can corrode in moist or acidic conditions.

4. Resin: 

A lightweight, flexible material used for unique jewellery designs.

 Corrosion Resistance: Excellent; generally immune to corrosion, though can degrade under UV light or extreme temperatures. 

Many people worry that the adhesive on labels might damage their jewelry. However, the adhesive used in Dymo 30299 labels is designed to be safe and won’t harm your jewelry. Here’s why:

1. Neutral Adhesive:

Betckey labels use a neutral adhesive formula that has passed the strict FDA certification, so you don’t need to worry about it damaging your jewelry. The FDA (Food and Drug Administration) sets high safety standards to make sure that products are safe for use, especially when they come into contact with sensitive items like food, skin, or jewelry. For an adhesive to pass FDA certification, it means it has been tested and proven not to contain harmful chemicals or cause any damage, which is why you can trust it to be safe for your jewelry.

2. Non-toxic and Safe Materials:

The adhesive is non-toxic and eco-friendly, ensuring that it doesn’t release harmful chemicals that could corrode jewelry or affect its surface.

3. Moisture-resistant Design:

Some labels also have waterproof and moisture-resistant properties, reducing exposure to humidity or acidic substances and further lowering the risk of corrosion.
