Cross-linking Agent
Crosslinking agent called bridging agent, is an important component of light hydrocarbons to resist, the photoresist photochemical curing effect, depends on the crosslinking agent with double photosensitive functional groups to participate in the reaction, crosslinking agent double free radicals after exposure, its function, and hydrocarbon resin phase in the bridge bond formed between polymer molecular chain, into the three dimensional structure of insoluble substance.
How to choose suitable cross-linking agents?
For different cross-linking agents, should choose suitable for its use of cross-linking agents, cross-linking agents have the following requirements:
The active group of the crosslinking agent can react with the components in the adhesive to form a crosslinking structure.
The cross-linking efficiency is high, and stable cross-linking structure can be obtained as long as a small amount is added.
The crosslinking speed is suitable, too fast too slow are unfavorable.
The best comprehensive effect can be obtained when several crosslinking agents are mixed.
Cross-linking agent in process treatment and storage period is stable, no harmful reaction and condensation. No poison, no irritation, no pollution of the environment.
