Principle of antifogging agent
The anti-fogging agent adopts a new generation of dispersed anti-dripping materials and nano organic active agents. The glass surface treated by the anti-fogging agent has a super hydrophilic nano film, which makes the fog contact with it to form a low freezing point mixture to prevent fogging .Maintaining time can be as long as 15 days. And non-toxic, non-odor, non-corrosive.
Classification
According to the way the anti-fogging agent is added to the plastic, the anti-fogging agent can be divided into two types: the internal addition type and the external coating type. The internal addition type anti-fogging agent is added to the resin during the batching, and its characteristics are that it is not easy to lose and has long-lasting performance. , But it is difficult to obtain good anti-fogging properties for polymers with higher crystallinity; the outer coating type anti-fogging agent is dissolved in organic solvents or water and applied to the surface of the plastic film, and is easy to use, low in cost, but has poor durability It is easy to be washed off or wiped off. It can only be used when the built-in anti-fogging agent is ineffective or when durability is not required.
