Hydroxyapatite Ca10(PO4) 6(OH) 2(HA) bioceramic composition is close to the inorganic composition of human bone, has good biocompatibility, and can form strong chemical binding with bone, It is an ideal alternative material for hard tissue. However, the current HA implant has high elastic modulus and low strength, and its activity is not satisfactory. By using phosphate glass adhesive, HA raw powder is bonded together under the traditional sintering temperature, which reduces the elastic modulus and ensures the material activity.

Cohen Technologies Ltd. recently announced that it has developed a Cosial sealed glue that can be used for heart bonding and has been successfully used clinically. The use of Cosel surgery in 21 cases of heart surgery in Europe was found to significantly reduce surgical adhesion compared to other methods. Subsequent preliminary clinical studies have shown that Cosial sealed glue has great development in heart, gynecology and abdominal surgery. potential. The application of adhesives in medicine has been hailed as a new growth point of adhesives industry. Structural glue consisting of epoxy resin or unsaturated polyester. In contemporary defense technology, stealth submarine is one of the symbols of naval equipment modernization. An important method of submarine stealth is to lay a muffler tile on the submarine shell. The muffler tile is a kind of rubber with sound absorption properties. In order to achieve the solid combination of silencing tiles and hull wall steel plates, it depends on adhesives.
