1, which contains different components:
Super glue is a kind of industrial glue, which contains organic solvent toluene.
UV adhesives include: epoxy acrylate, polyurethane acrylate, polyether acrylate, polyester acrylate, acrylic resin, etc.
2. Different characteristics:
Cyanoacrylate in super glue is an acrylic resin, which can be bonded almost instantly (forming its strongest chemical bond). The only reaction initiator it needs is hydroxyl ion in water. Hydroxyl ions are easy to obtain, because almost any surface you want to bond contains hydroxyl ions.
UV glue can be positioned in a few seconds and reach the highest strength in one minute; It is completely transparent after curing, and the product does not turn yellow or white for a long time; It has the characteristics of environmental resistance, no whitening, good flexibility and at least a little moisture.
3. Different application fields
Super glue:
Medical application: α -cyanoacrylate medical adhesive is a kind of instant adhesive, which has the characteristics of one component, no solvent, no pressure during bonding, rapid curing at room temperature and no special treatment after bonding.
Application in automobile industry: Metal automobile parts can be bonded together, which is of great significance to future automobile manufacturing. This new super adhesive contains a newly developed adhesion promoter, which can be used to firmly bond metal parts together without welding.
UV glue:
Craft glass: glass products, glass furniture, electronic scales bonding; Crystal jewelry craft products, fixed inlay; Adhesion of transparent plastic products.
Micro-motor: fixed, wire circuit board bonded and fixed; CD-ROM drive: fixed laser head, fixed lens and fixed circuit board; Transfer printing: transfer printing adhesive and surface protection adhesive; Bonding of automobile industry parts: bonding of automobile lamp assembly, automobile rearview mirror and airbag parts and fuel injection system.
