B 678-0 Spacer

B 678-0 Spacer

Product number: BO5209362S

Description

B 678-0 Spacer offers the possibility to bond larger surfaces due to its elasticity. The spacers ensure that there is sufficient adhesive over the entire surface. The higher weight of larger adhesive parts is compensated. Spacers are not visible. The clear appearance remains.

B 678-0 is also light-curing, so laminated safety glass and other UV-impermeable glass can be used. In combination with Pyrosil® it is also often possible to produce objects for outdoor use. B 678-0 equalises tensions and compensates for the different expansion rates of different materials. When bonding with wood, stone or plastics, test bonding must always be carried out

Very sensitive to light. If necessary, darken ambient light during processing to avoid premature curing.

Application note:
Observe the safety data sheet, the processing instructions and the relevant technical guidelines and standards
