Abstract
A bonding structure used for forming a sealed space (for example, a container) for containing or transferring an organotin compound, wherein the bonding structure is a structure in which a first metal member (for example, a lid of the container) is connected to a second metal member (for example, a container body of the container) via a metal gasket or a metal O-ring, and the metal gasket or the metal O-ring has a surface having a Vickers hardness set to be not less than lower than a Vickers hardness of a surface of a portion of the metal member, the portion being contacted with the metal gasket or the metal O-ring.
Claims17
A container comprising a bonding structure, wherein the bonding structure comprises:
- a first metal member;
- a second metal member having a portion connected to the first metal member via a metal gasket or a metal O-ring,
- wherein the metal gasket or the metal O-ring has a contact surface having a Vickers hardness of from 150 to 200;
- wherein a contact surface of the portion of the first and second metal members has a Vickers hardness of from 180 to 300;
- wherein the Vickers hardness of the contact surface of the metal gasket or the metal O-ring is from 10 to 120 lower than the Vickers hardness of the contact surface of the portion of the first and second metal members, and
- wherein the container is filled with an organotin compound having formula (1):
- wherein R is a hydrocarbon group, p is 0 or 1, X is a hydrolysable substituent, m is an integer of 1 to 4, and m+p is 2 or 4.
A container, comprising a bonding structure, wherein the bonding structure comprises:
- a first metal member;
- a second metal member having a portion connected to the first metal member via a metal gasket or a metal O-ring,
- wherein the metal gasket or the metal O-ring has a contact surface having a Vickers hardness of from 150 to 200;
- wherein a contact surface of the portion of the first and second metal members has a Vickers hardness of from 180 to 300;
- and
- wherein the Vickers hardness of the contact surface of the metal gasket or the metal O-ring is from 10 to 120 lower than the Vickers hardness of the contact surface of the portion of the first and second metal members.
