A summary of common basic knowledge in the adhesive industry(Ⅳ)

Classification nouns (2)

21. Solvent-activated adhesive is an adhesive that uses a solvent to activate the dry adhesive film before use to make it sticky and complete the bonding.

22. Solventless adhesive is a solvent-free liquid, paste, or solid adhesive.

23. Sealing adhesive, an adhesive that plays a sealing role.

24. Anaerobic adhesive: An adhesive that inhibits curing when oxygen is present and cures itself when oxygen is isolated.

25. Photosensitive adhesive: An adhesive that relies on light energy to initiate curing.

26. Pressure-sensitive adhesive: A viscoelastic material that has long-lasting viscosity when it exists in a solvent-free state. The material instantly bonds to most solid surfaces with gentle pressure.

27. Pressure-sensitive adhesive tape: a tape-shaped product that applies pressure-sensitive adhesive to the base material.

28. Multiple layer adhesive: A film composed of different adhesives on both sides, usually with a carrier. Generally used for the bonding of core materials and panels in honeycomb sandwich structures.

29. Foaming adhesive: An adhesive that foams and expands in situ during curing, and relies on a large number of gas cells dispersed throughout the entire adhesive layer to reduce its apparent density.

30. Foamed adhesive (cellula adhesive): An adhesive that contains countless inflated microbubbles, thereby significantly reducing its surface density.

31. Encapsulated adhesive: An adhesive that encapsulates particles or droplets of reactive components in a protective film (microcapsule) and prevents solidification before the protective film is destroyed by appropriate methods.

32. Electric conductive adhesive: An adhesive with conductive properties. This adhesive generally contains conductive powders such as silver, copper, and graphite.

33. Heat activated adhesive: a dry adhesive that is made sticky by heating.

34. Hot-melt adhesive: An adhesive that is applied while molten and then cooled to a solid state to complete the bonding.

35. Contact adhesive: Apply to the surface of two adherends, dry and stack them together to form an adhesive with bonding strength without maintaining pressure.

36. Water-borne adhesive (aqueous adhesive): An adhesive that uses water as the solvent or dispersion medium.

37. Water-resistant adhesive: An adhesive that can maintain its bonding performance (or usage performance) even if the bonded parts are often exposed to moisture.

38. Hot-setting adhesive: An adhesive that requires heating to harden.
