1. Mixing the two components
The components A and B are mixed by weight in the above indicated ratio. The mixing
can be carried out either by hand or using a low-speed electric or pneumatic mixer to
minimise the introduction of air and to avoid any temperature increase.
It is also possible to use a special mixing and dispensing machine for the two silicone
components. Further information is available upon request.
The mixture should be degassed preferably at 30 to 50 mbar to eliminate any
entrapped air. If a dispensing machine is used, the two components are degassed
separately prior to mixing.
The silicone mixture expands to 3 to 4 times of its initial volume and bubbles rise to
the surface. The bubbles progressively disappear and the mixture returns to its initial
volume after 5 to 10 minutes. Wait a few minutes to complete the degassing and then
flash the vacuum. The silicone is ready for pouring, either by gravity or under low
Note: Flashing the vacuum once or twice accelerates the degassing. It is
recommended to use a container with a high diameter / height ratio.
The system polymerises at 23°C. The curing may be slowed down at lower
temperature and contrary accelerated by heat.
Contact with certain materials can inhibit the crosslinking. See list below:
· natural rubbers vulcanised with sulphur
· RTV 2 silicone elastomers catalysed with metal salts, e.g. tin-compounds
· PVC stabilised with tin salts and additives
· epoxy resins catalysed with amines
In case of doubts, it is recommended to test the substrate by applying a small quantity
of the mixed silicone on a restricted area.
SILBIONE RTV 4410 1/1 B 储存温度介于 -10°C / 14°F 和 30°C / 86°F 之间时，从生产日期开始产品保质 6 个月
SILBIONE RTV 4410 1/1 B
The SILBIONE RTV 4410 1:1, 4410 QC Trans, 4411 A & B are two component
silicone elastomers that crosslink at room temperature by polyaddition reaction. The
polymerisation can be accelerated by heat.
The silicone materials are delivered as two low viscous liquid components, which once
mixed and cured, transform into an elastic and resistant material. Polymerisation
occurs without formation of heat.
