【Deep Coating Society Popular Science Knowledge】What is the role of silicone resin in the production of special paper?

What is the role of silicone resin in the production of special paper, among many silicone materials, silicone materials are the most widely used one, and its excellent performance allows silicone resin to play a role
in many industries.
In the production of special paper, silicone resin is also used, today Xinjiayi Xiaobian will take you to understand what role silicone resin plays in the production of special paper, let's
take a look.

The coating concentration and coating amount of silicone resin applied to the peeling paper must be appropriately selected
according to the nature of the paper.
Generally speaking, the solid silicone resin content in the paper should be 0.
5G/M2, which can be coated by Meyer type coater or roller coater
.
After drying, heat treatment
is carried out at 120-180°C.
The amount of silicone resin coated has a certain relationship with the peeling performance of the paper, which in turn depends on the density of the base paper or the quality of the
original pulp.
For example, cellophane with high smoothness and chemical resistance, as well as substrates with similar properties to cellophane, can be fully effective because silicone resins penetrate slowly and tend to remain on the paper web
.

Whether solvent-based or emulsion-based silicone resins are used, in the case of a small amount of resin, the silicone often penetrates into the paper in large quantities, and the expected peeling effect
is not obtained.
In short, whether a stripping paper can achieve the desired peeling effect also depends on how much
silicone remains on the paper.
In order to improve the density and smoothness of the paper, a layer of hydrophilic film-forming substances such as polyvinyl alcohol can be pre-coated on the paper and properly calendered
.

Stripping paper made from non-adhesive processing of silicone resin has many
uses.
For example, just as a pressure-sensitive sticker paper, there are many varieties of goods, such as pasted wallpaper, pasted tiles, pasted cardboard, and decorative materials for doors and windows
.
In addition, adhesive paper tape, adhesive paper, sealing tape, etc.

are used as daily necessities.

Silicone resin has excellent performance and can play many roles in the production of special paper, in addition to many products in life are also related
to silicone resin.
