Waterproof materials are widely used products in the market. In the aquatic products industry, as well as in raincoats, umbrellas, etc., such labels are all made of waterproof materials.
Base Materials
PVC (Polyvinyl Chloride)
It has good waterproof performance, is soft in texture and has a certain elasticity, which can fit the surfaces of various shaped objects well. For example, it can adhere perfectly to the surface of even very rough paper. Therefore, the advantage of this PVC material is its wide range of applications.
It has strong chemical corrosion resistance and is not easily eroded by substances such as water, acids and alkalis. It can maintain stable performance in different environments, which means it has strong adaptability. It can be used in various different weather conditions and harsh climates. So, for extremely cold and extremely hot regions, these materials can be used to solve the problems.
The cost is relatively low, and it has good processing performance. It can be surface-treated through processes such as printing and coating to make waterproof stickers in various colors and patterns.
PET (Polyethylene Terephthalate)
It has excellent water resistance and moisture resistance, and can effectively block the penetration of water.
It has high mechanical strength, is tough and durable, and is not easy to tear or break. It can maintain good physical properties even in a humid environment. This material has good water resistance and strong tolerance, and can exist well in any environment.
It has high transparency and can be used to make transparent waterproof stickers, which can clearly display the content of the pasted object. At the same time, it has good printing adaptability and can achieve exquisite printing effects.
PP (Polypropylene)
It has good waterproof performance, as well as certain flexibility and tensile resistance, and can adapt to the deformation and bending of the object surface. In addition to its good waterproof performance, it also has strong flexibility, that is, it can be well preserved in any environment.
It is wear-resistant, has good chemical stability, has good tolerance to water and most chemical substances, and is not prone to hydrolysis or corrosion.
It has a relatively low specific gravity and a thin texture, which is convenient for processing and use. It is suitable for making various types of waterproof stickers, especially in application scenarios that require lightweight materials.
Adhesives
Acrylate Adhesive
It has good adhesion to a variety of base materials and can form a strong bond with the surface of the object in a wet or underwater environment.
It has strong water resistance. The adhesive layer formed after curing has excellent waterproof performance and can effectively prevent water from penetrating between the sticker and the object surface.
It has good weather resistance and chemical resistance, and can maintain stable bonding performance under different environmental conditions. It is not easily affected by factors such as water, ultraviolet rays, and temperature changes.
Silicone Rubber Adhesive
It has excellent waterproof performance and can maintain good sealing and bonding effects in various harsh water environments.
It has excellent high-temperature and low-temperature resistance, and can maintain elasticity and stickiness within a wide temperature range, adapting to use in different climatic conditions.
It has good adhesion to a variety of materials, especially to common pasted object surfaces such as plastics, metals and glass, and can ensure that the waterproof sticker is closely combined with the object.
Polyurethane Adhesive
It has good water resistance and moisture resistance, and can quickly cure and form a high-strength bond in a humid environment.
The adhesive layer has excellent flexibility and impact resistance, and can adapt to the slight deformation and vibration of the object surface. It is not easy to crack or fall off, thus ensuring the long-term waterproof effect of the waterproof sticker.
It has good bonding performance to a variety of base materials, and the formula can be adjusted according to different application requirements to meet the use requirements of various waterproof stickers.
Surface Coatings
Waterproof Varnish
It forms a transparent protective film on the surface of the sticker, effectively blocking the contact between water and the sticker base material and adhesive, and improving the waterproof performance.
It has good wear resistance and scratch resistance, can protect the surface of the sticker from damage by external factors, and prolong the service life of the waterproof sticker.
The glossiness of the varnish can be adjusted according to needs, so that the waterproof sticker has different appearance effects, such as matte, semi-gloss or high-gloss, etc., to meet the aesthetic needs of different customers.
Fluorocarbon Coating
It has an extremely low surface energy, which can make water droplets roll off the surface of the sticker, thus achieving excellent waterproof effect. At the same time, it also has a self-cleaning function and is not easy to be stained with dust and dirt.
It has excellent weather resistance, can resist the erosion of natural factors such as ultraviolet rays and acid rain, and is not easy to fade, age or lose its waterproof performance when exposed to the outdoor environment for a long time.
The coating has high hardness and strong wear resistance, can effectively protect the surface of the sticker, and improve its performance in various harsh environments.
Silicone Coating
It has good waterproofness and breathability. It can not only prevent water from entering the inside of the sticker, but also allow the water vapor on the surface of the pasted object to escape through the coating, avoiding the sticker from falling off or the object surface from being damaged due to the accumulation of water vapor.
It has good high-temperature and low-temperature resistance, and can maintain stable performance under extreme temperature conditions, suitable for the application of waterproof stickers in various different climatic environments.
The coating is soft and elastic, can adapt to the bending and deformation of the sticker on different object surfaces, and also has good tear resistance, enhancing the overall durability of the sticker.
