Problems solved by technology

At present, conventional primer components mainly include acrylic resin, silicone resin, polyester resin, PU glue, water-based resin and corresponding curing agent or other components. The main components of the formula are usually more than 3, plus The solvents used in the field are often multi-component, resulting in cumbersome process flow, many influencing factors, and difficult cost control
Moreover, for different coating materials, it is necessary to adjust the corresponding primer components reasonably, and it is often difficult for one primer to be used for different coating materials.

Abstract

The invention discloses a primer. The primer comprises reactive silane and a solvent. The invention further discloses a thin film containing a primer layer. The thin film comprises a base film and the primer layer formed by curing the primer on the surface of the base film. A primer layer formed by the primer can improve the binding force between a film coating material and a film, so that the requirement of adhesiveness can be met without adding an anchoring agent in a silica gel and silicon release film formula, and the primer is simple in formula, suitable for various film coating materials such as a pressure-sensitive adhesive, silica gel and a silicon release agent and high in universality.

Description

technical field [0001] The invention relates to the technical field of film surface treatment, in particular to a primer and a film containing the primer. Background technique [0002] In the fields of display and optoelectronics, in order to meet the needs of various occasions, it is often necessary to compound coating materials such as silica gel and silicon release agent with polyester films for use in display and optoelectronic materials. Due to the poor interface wettability of the polyester film, the adhesion with the silica gel and the silicon release agent is not good, and it is easy to separate the adhesive layer from the film layer, and the adhesive layer falls off, resulting in defects. In order to solve this problem, the commonly used method is to add anchoring agent to the components of silica gel and silicon release agent, so as to improve the adhesive performance of the adhesive layer formed on the polyester film surface. However, the addition of the anchorin...
