Description:
Vacuum Bag Silicone is great to make reusable silicone bag process for automotive industry like truck body panels, construction of formula racing cars, manufacture small/medium sized turbine blades, building cladding panels and architectural trim panels, marine industry, high-tech aerospace and defence industries is growing rapidly etc.
With traditional vacuum infusion the accepted solution for large scale products and RTM for smaller components, the reusable silicone bag process has a very useful place in the spectrum of processes , as it helps to bridge the gap between these two existing processes.
Features:
Using silicone for vaumm bag casting has many advantages:
1.) Low viscosity
2.) Fast gel time
3.) Long shelf life
4.) No shrinkage
5.) Resistance against epoxy resins&polyester
6.) Addition cure
Data Sheet:
Operation Method:
By brushing, spraying available
How does our customer use it?
1.)Flange seal details and moulded flow runners are positioned.
2.)Once the vacuum channel formers have been positioned, a spay machine is used to apply the bluesil silicone product to mold.
3.)The silicone is able to replicate complex details.
4.)Silicone is also used to form the peripheral sealing flange.
5.)Cloth is used to reinforce the bag in strategic areas and to increase durablility
6.)Metal inserts assist in lifting and handing the bag.Curing time in 20 mins
7.)Once the curing stage is over, it’s time to release the vacuum bag.
8.)The silicone bag is self-releasing. It will not adhere to master mold allowing for easy operator removal
9.)Now the’ A’ surface mould is cleaned and treated with release agent.
10. )A gel coat layer is then applied.
11. )The RTM type ‘ combination mat’s glass reinforcement is applied with foam cores used in some area.
12.)A layer of ‘flow-mesh’ can be used to accelerate resin flow.
13.)The silicone bag is positioned over the fibre leaving a cavity for the resion to fill.
14.)Connections are made to vacuum pump and the machine that will mix and inject the resin.
15.)The resin flows into the mould through the fibre
16.)After curing , the vacuum bag relsease from the newly formed boat hull, the bag is reusable , saving time and significantly increasing productivity
17.)If a’peel-ply’ layer has been used, it’s removed at his stage
18.)The moulding can now be released from the mould.
19.)The finished moulding is true to the original in every detail thanks to the state-of-the art silicone vacuum bag technology.
Storage:
Store in a cool and dry place 18 months from the date of production.
Warm Tips:
* It should be stored in a dry place in its original sealed container.
* Read the product safety data sheet(MSDS) carefully before using, which can be got from the supplier.
