Description

technical field

[0001] The invention belongs to the field of organosilicon chemistry, and in particular relates to a solvent-based paper release agent with a high residual adhesion rate and a preparation method thereof. Background technique

[0002] Paper release agent is mainly used in the production of release paper (also known as anti-adhesive paper), the purpose of which is to make the adhesive and the substrate easily peeled off. Therefore, release paper is widely used to make various pressure-sensitive tapes (paper sheets) and packaging materials for various sticky substances.

[0003] Silicone release agents are widely used due to their low toxicity, low surface energy, good wettability with substrates, wide range of temperature applications, and low migration to adhesives. Excellent paper release agents generally need to meet the following requirements: 1. Appropriate peeling force: The peeling force of the release layer to the adhesive layer can be divided into lig...
