1. Silica gel crystal drop: Silica gel crystal drop is a common crystal drop, mainly made of silica gel polymer. It has excellent transparency and adhesion, and can be used to bond glass, plastic, metal and other materials. Silica gel crystal drops also have the characteristics of high temperature resistance and good weather resistance, and are suitable for outdoor environment.
2.UV crystal glue drop: UV crystal glue drop is a kind of crystal glue that needs ultraviolet radiation to cure. It usually exists in liquid form, and only when it is irradiated by ultraviolet rays will it quickly solidify into a transparent solid. UV crystal glue drops have the characteristics of fast curing speed and high bonding strength, and are suitable for electronic component packaging, glass repair and other occasions requiring rapid curing.
3. Hot-melt crystal dripping glue: Hot-melt crystal dripping glue is a kind of crystal dripping glue that needs heating to melt. It usually exists in the form of solid particles or strips. It needs to be heated by hot melt glue gun before it becomes liquid, and then it drops on the object to be bonded. Hot melt adhesive drops have the characteristics of fast curing speed and high bonding strength, and are suitable for bonding various materials, such as wood, paper and cloth.
4. Two-component crystal drops: Two-component crystal drops are composed of two different liquid components, which need to be mixed in a certain proportion. This kind of crystal glue usually has high bonding strength and durability, and is suitable for bonding metals, ceramics and other materials that need to bear large forces.
5. Waterborne crystal drops: Waterborne crystal drops are crystal drops with water as solvent. Compared with other types of crystal drops, it is more environmentally friendly, non-toxic and non-irritating. Water-based crystal drops are suitable for some occasions with high environmental requirements, such as food packaging, medical devices and so on.
In short, there are many kinds of crystal drops, including silica gel crystal drops, UV crystal drops, hot melt crystal drops, two-component crystal drops and water-based crystal drops, each of which has its own unique characteristics and application scope. When choosing to use, it is necessary to choose the appropriate crystal drops according to the specific needs and material characteristics.
