The differences and advantages of water-based acrylic pressure sensitive adhesive and other pressure sensitive adhesive

Compared with other types of Water-based Acrylic PSA, it has the following advantages and differences:

1. Chemical composition: Water-based acrylic pressure sensitive adhesive is emulsion adhesive with water as solvent, and other pressure sensitive adhesive is usually based on organic solvent adhesives.
2. Environmentally friendly: Water-based acrylic pressure sensitive adhesive has a lower volatile organic compounds (VOCs) content, reducing environmental pollution and complying with environmental regulations. Other organic solvent-based pressure sensitive adhesives may contain more VOCs.
3. Safety: Water based acrylic pressure sensitive adhesive as a solvent in the water, relatively safe. It does not burn easily and poses a low health risk to people and the working environment.
4. Bonding properties: Water-based acrylic pressure sensitive adhesive has good initial viscosity and shear properties, and can provide reliable bonding properties over a wide range of temperatures. It has good adhesion and peeling power, suitable for a variety of surface materials.
5. Adjustability and adjustment: the composition of water-based acrylic pressure sensitive adhesive can be changed by adjusting the formula to change its bonding performance, such as increasing high temperature resistance and improving bonding strength. This allows it to be customized to the requirements of a particular application.
6. Drying speed: Water-based acrylic pressure sensitive adhesive evaporates water during the drying process, so it usually takes longer drying time to achieve the best bonding properties. In contrast, other organic solvent-based pressure sensitive adhesives may dry faster and are suitable for applications requiring rapid bonding.

   

It is important to note that water-based acrylic pressure sensitive adhesives also have some limitations, such as their sensitivity to water, so their performance in wet environments may be affected. In addition, under some specific extreme conditions such as high temperature and chemical resistance, other types of pressure sensitive adhesive may perform better. Therefore, in the selection of adhesives, it is necessary to consider the characteristics and advantages and disadvantages of different types of pressure sensitive adhesives according to the specific application requirements.
