A Summary of Common Basic Knowledge in The Adhesive Industry (Ⅱ)

Ⅱ. Ingredients

1. Binder: The substance that mainly plays a bonding role in the adhesive formula.

2. Curing agent hardening (agent hardener): a substance that directly participates in chemical reactions to cure the adhesive.

3. Latent curing agent: A curing agent that is chemically inert under normal conditions and works under specific conditions.

4. Blocked curing agent: A curing agent or hardener that temporarily loses chemical activity and can be reactivated by physical or chemical methods as required.

5. Accelerator promoter: a substance that promotes chemical reactions, shortens curing time, and lowers curing temperature in the formula.

6. Diluent: a liquid substance used to reduce the viscosity and solid content concentration of the adhesive.

7. Reactive diluent: A diluent that contains active groups in the molecule and can participate in the curing reaction.

8. Dispersing agent: a substance that disperses adhesive components in the medium.

9. Filler: a non-adhesive solid substance added in order to improve the performance of the adhesive or reduce costs.

10. Modifier modifying agent: An ingredient added to the adhesive formula to improve its performance. Such as fillers, tougheners and other substances.

11. Stabilizer: A substance that helps the adhesive maintain its stability during preparation, storage and use.

12. Tackifier: A substance that can increase the viscosity of the adhesive film or expand the viscosity range of the adhesive.

13. Thickener: A substance added to increase the apparent viscosity of the adhesive.

14. Flexibilizer: A substance in the formula that improves the brittleness of the adhesive and increases its toughness.

15. Catalyst: A substance that can change the rate of a chemical reaction and theoretically maintain its chemical properties unchanged at the end of the reaction.

16. Extender: A substance that has a little adhesive effect, but is mainly added to the adhesive to reduce costs.

17. Inhibitor retarder: A substance that can inhibit chemical reactions and can be used in certain types of adhesives to extend their storage or pot life.

18. Release paper: protective paper for film and tape. It is easily removed from the film or tape before use.
