What is the difference between water-based adhesive and Silicone Adhesive?
1. Different in nature

Silicone adhesive is an organic polymer material, and water-based adhesive is a very hydrophilic three-dimensional network structure gel, so the properties of the two are different.

2. Different characteristics

Waterborne glue can expand rapidly in water, and can keep a large amount of water in this expanded state without dissolving. Silicone adhesive is hydrophilic and has a framework of biphasic materials.

3. Different uses

As a kind of material with high water absorption and water retention, water-based adhesive is widely used in drought resistance in arid areas, facial mask in cosmetics, antipyretic patch, analgesic patch and many other fields. Silicone adhesive is often used to make contact lenses.

4. Different oxygen permeability

The oxygen permeability of silicone contact lenses is generally five times that of water-based contact lenses. Because the oxygen permeability of hydrogel contact lenses is closely related to its water content, generally speaking, hydrogel products with high water content will have higher oxygen permeability and higher corneal metabolic permeability.
