Besides, if you are planning to use stickers on expensive items (laptops, phones or cars…), we also recommend using removable sticker glue.
3. Repositionable Adhesive
For those who require even greater flexibility, repositionable adhesive is a suitable choice. With repositionable adhesive, stickers can be easily removed and repositioned multiple times without losing adhesive properties. This is especially beneficial when precise placement is crucial, such as stickers for window glassdoor, or office wall, because this allows for adjustments and ensuring a perfect alignment.
Types of sticker adhesive according to the substance used
Sticker adhesives also come in various types based on the substances used in their composition.
1. Water-Based Adhesive
Water-based sticker adhesive is an environmentally friendly option, as it is primarily composed of water, combined with polymer and additives. It is commonly used for paper labels and general-purpose applications, offering low toxicity and low odor.
2. Solvent-Based Adhesive
Solvent-based adhesive, on the other hand, is made up of organic solvents and synthetic resins. It provides excellent bonding strength and is often chosen for applications that require durability, such as outdoor labels or industrial use.
However, it’s important to note that solvent-based adhesives may contain higher levels of volatile organic compounds (VOCs). When these adhesives are used, the VOCs can be released into the air. Prolonged exposure to VOCs may lead to respiratory irritation, headaches, dizziness, and other health issues. Additionally, VOC emissions from solvent-based adhesives contribute to environmental pollution and can have a negative impact on air quality and ecosystems.
3. Acrylic Adhesive
Acrylic sticker adhesive, composed primarily of acrylic polymers, offers excellent bonding strength on different surfaces such as plastic, metal, and glass. It exhibits good resistance to UV rays, moisture, and temperature variations. Acrylic adhesives are often used in durable labels, automotive applications, and outdoor stickers.
4. Rubber-Based Adhesive
Rubber-based sticker adhesive is made from natural or synthetic rubber polymers. It offers good initial tack and flexibility, making it suitable for applications that require conformability, such as curved or uneven surfaces. For example, rubber-based adhesives are commonly used in promotional stickers that are applied to uneven street walls.
Types of sticker adhesive based on the way they are activated
1. Hot Melt Adhesive
Hot melt adhesive, typically composed of thermoplastic polymers, resins, and additives, is a solid adhesive that melts when heated, providing fast and reliable bonding. It is frequently used in high-speed labeling and packaging applications, bonding well with various materials including paper, plastic, and metals.
2. Pressure-Sensitive Adhesive
Pressure-sensitive sticker adhesive is tacky at room temperature and forms a bond when pressure is applied. It is commonly found in self-adhesive labels, tapes, and stickers, providing instant adhesion without the need for additional heat or solvents.
Things you need to consider when choosing sticker adhesive
1. Surface Compatibility
First and foremost, evaluate the surface compatibility. Different adhesives have varying levels of compatibility with different surfaces, such as paper, plastic, glass, metal, or fabric. Ensuring that the adhesive is suitable for the specific surface will ensure optimal adhesion.
2. Bonding Strength
Another important consideration is the bonding strength required for your stickers. Consider the weight or size of the sticker, the intended application, and the expected environmental conditions. Some applications may require stronger adhesive labels to ensure long-term adhesion, while others may require a more temporary or removable adhesive option.
3. Removability
Removability is a crucial factor to think about, especially if you anticipate the need to reposition or remove the stickers without leaving residue or causing damage. Depending on your requirements, you can choose between permanent sticker labels that offer a strong and long-lasting bond or removable adhesives that allow for easy removal without residue.
4. Temperature Resistance
Temperature resistance is also a vital consideration, particularly if your stickers will be exposed to extreme temperatures. Some adhesives perform well in high heat or freezing conditions, while others may lose their adhesive properties. It’s important to choose an adhesive that can withstand the temperature variations of your intended application.
5. Environmental Factors
Environmental factors should also be taken into account. Consider the stickers’ exposure to moisture, humidity, UV rays, or chemicals. Select an adhesive that is specifically designed to withstand these conditions and maintain its adhesion. This ensures that your stickers will remain securely attached even in challenging environments.
6. Application Method
The application method is another aspect to consider. Some adhesives are suitable for manual application, while others may require automated processes. Ensure that the adhesive you choose is compatible with your intended application method for ease of use and efficiency.
7. Health and Safety
Lastly, it’s important to consider health and safety aspects associated with the adhesive. Some adhesives may contain volatile organic compounds or other potentially harmful substances. If necessary, choose adhesives that meet specific health and safety regulations or opt for low-contain volatile organic compounds or eco-friendly options to minimize any potential risks.
