How to Get Vinyl to Stick to Silicone
Silicone is the latest and most popular product today. You can find them everywhere from tumblers to bracelets. Since its introduction to the market, hobbyists and DIYers were fascinated and wondered if they could embellish their silicone accessories with vinyl. The question is will the vinyl stick? Let’s find out. First, let’s take a brief overview of silicone
Properties of Silicone
Silicone is a polymer made up of siloxane, typically colorless oils or rubber-like substances. Its chemical composition and structure give it unique properties and various useful applications. This material has the high bonding energy of the silicon-to-oxygen (Si-O) backbone.
This makes silicone an ideal material for use in harsh environments, such as in the aerospace and automotive industries, where it can withstand extreme temperatures and exposure to chemicals.
Silicone also exhibits excellent thermal stability and resistance to high and low temperatures. Its low thermal conductivity can be described as high thermal (heat) resistance, making it ideal for use in high-temperature applications. Another property of silicone is its water-repellency and resistance to weathering.
So, will vinyl stick to silicone? It’s a challenging task but it’s possible. But you need to use the right type of vinyl. Let’s continue the discussion.
How to Apply HTV and Vinyl Stickers on Silicone
Vinyl is not meant to adhere well to silicone surfaces. So, applying heat transfer vinyl (HTV) and vinyl stickers on silicone can be a challenging task. However, with the right techniques and materials, it is possible to achieve a successful application.

Clean the Surface of the Silicone
The first step is to prepare the silicone surface by cleaning it thoroughly with rubbing alcohol to remove any dirt or oils that may prevent proper adhesion. It is important to ensure that the surface is completely dry before proceeding with the application. Silicone free of nubs, grooves, and serrations is the best surface for applying your design.
Choose the Right Vinyl
Then, select the right vinyl. This step is crucial for the successful application of silicone. We recommend stretchable or silicone HTV for its ability to conform to the flexible and stretchy surface of the silicone.
It is also important to select a vinyl that is suitable for the intended use, such as a vinyl that is durable and waterproof for items that will be exposed to frequent use and washing.
PVC vinyl is the most common type for this application, as it offers good adhesion and flexibility. However, you may also want to consider using polyurethane vinyl, which is more durable and resistant to wear and tear.
Both types of vinyl should be applied with a specialized adhesive designed for silicone. It’s important to follow the instructions on the adhesive package to ensure proper adhesion.
Apply Your Designs
Depending on the vinyl you choose, the application may differ a bit. For heat transfer vinyl, you will need additional tools such as a mug heat press. After choosing the design, use a cutter and weed off the excess vinyl.

Applying heat and pressure is the final step in achieving proper adhesion of HTV on silicone. Use the appropriate type of heat press with accurate temperature and pressure settings. While applying, use a carrier sheet to protect the vinyl during the application process.
The recommended temperature for applying HTV on silicone is between 300-320°F, and the pressure should be even and steady to ensure a strong bond between the vinyl adhesive and the silicone surface.
Certain types of stickers are better suited for sticking to silicone than others. Vinyl stickers are known to stick well to silicone surfaces, making them a great option for decorating phone cases or tablet covers.
Teckwrap Craft vinyl stickers, a type of high-performance polyester, are specifically designed to permanently adhere to silicone and siliconized surfaces. However, not all stickers will adhere well to silicone surfaces, and some may require additional adhesive support to stick.
The adhesiveness of stickers on silicone can vary depending on several factors. One of the primary factors affecting sticker adhesion is the type of adhesive used on the sticker.
Rubber adhesives, for example, are known for their high-tack and can adhere well to surfaces such as silicone, Teflon, plastics, and even rubber itself.
Additionally, the strength of the adhesive, the length of time the label is stuck onto the case, the surface texture of the silicone case, and the type of sticker being used can all play a role in determining the sticker's ability to adhere to the silicone surface.

Allow To Cure
Depending on layer thickness, the product takes 24 - 48 hours to fully cure. Temperature and humidity also affect the curing process. A humid environment will cure the product faster than a dry environment.
Although adhesive vinyl or HTV are quick dry once you finish the application, you still need to let the adhesive backing work its magic on the silicone. Test out your work by applying some pressure with your fingers - if it holds then you have successfully applied your vinyl onto your silicone surface!
Tips for Getting Vinyl to Stick to Silicone
Heating vinyl can also help it adhere better to the silicone surface. Using a hairdryer or heat gun on the surface of the vinyl can help dry the adhesive and affix it better.
It is important to be careful when using heat, as too much heat can damage the vinyl or the silicone surface. Additionally, giving the adhesive time to cool off and bond with the silicone surface is crucial.
Avoid silicone items that are too flexible. Siliconized ones will be perfect and your adhesive vinyl will work fine. Additionally, using strong adhesives, such as transfer tapes, can help improve the vinyl's ability to stick to the silicone surface.
Finally, ensuring that the vinyl sticker is applied evenly and with enough pressure can also help improve its adhesiveness to the silicone case.
Factors that Affect the Adhesion to Silicone
Silicone is a flexible material that may cause the hot glue to stretch and become misshapen when applied. To avoid these issues, it is best to avoid putting your silicone tumbler or lunch boxes near direct heat.
You're using old adhesive vinyl. Although these materials don't expire, the effectiveness of adhesive backing might deteriorate over time, especially if the vinyl were not stored properly.
For HTV, you might not be using the right temperature. Make sure to check on the appropriate setting for the vinyl you're using. Always read the instructions if the vinyl is a cold or hot peel.
