A non-stick, durable, and long-serving coating in an inner surface of a tube that transports adhesive, a material of the coating includes polysiloxane. The polysiloxane includes a first monomer unit and a second monomer unit. The first monomer unit is at least one group selected from the group consisting of —O—Si—(R1)(R2)(R3), Si—(R1)(R2)(—O—)2, and Si—(R1)(—O—)3, the R1, R2 and R3 being independently selected from the group consisting of substituted alkyl and unsubstituted alkyl. The second monomer unit includes Si(—O—)4. An injection needle and a method for manufacturing the coating on an injection needle is also provided. |
