Best Water based release agent manufacturers talk about the principle of the release agent
The release agent is a functional substance between the mold and the finished product. The release agent is chemically resistant and will not be dissolved when it comes in contact with the chemical components of different resins. Do you know what the working principle of the release agent is? Follow the editor of Best Water based release agent manufacturers to have a simple look at it!
1. The polar chemical bond interacts with the mold surface to form a regenerative adsorption film;
2. The silicon-oxygen bond in polysiloxane can be regarded as a weak dipole. When the release agent is spread on the surface of the mold into a single orientation arrangement, the molecule adopts a unique extended chain configuration;
3. The free surface is covered by alkyl groups in a densely packed manner, and the demoulding ability increases with the density of the alkyl group; but when the alkyl group occupies a large steric hindrance, the stretching configuration is limited, and the demolding ability will be reduced;
4. The molecular weight and viscosity of the release agent are also related to the release ability. The molecular weight is small and the spreadability is good, but the heat resistance is poor.
In summary, the editor of Best Water based release agent manufacturers tells about the relevant knowledge about the principle of the release agent.
