Silicone rubber adhesive, Neutral General purpose silicone adhesive, RTV, silicone adhesive dots
SI3333 coating is room temperature curing one component organic silicone filling adhesive. With moisture, dust and corona proof, cushion and earthquake proof, SI3333 is one kind of self-levelling and flowing room temperature dealcoholized silicone adhesive, it exactly complies with the requirements of the EU RoHS.
Features
1. One-component, easy handling
2. Cured fast within 10mins
3. Good adhesion to most substrates
4. No corrosion to most material, eg. Metal Cu and PU plastic.
5. Stable and flexible at the temperature -60° C to +250° C
Usage
1 Designed to provide long term bonding and to protect against moisture, environmental attack, mechanical and thermal shock as well as vibration especially where a high strength product is required.
Typical applications include: Bonding of sensitive electronic components and sub-assemblies.
Operation:
1. Cleaning: Cleaning the surfaces that to be glued and coated, removing the rust, dust, greasy dirt and other foreign matter and substance.
2. Gluing: Cutting nozzle to the required angle, extruding the liquid cement to the cleaned surface and making it well-distributed, then folding and fixing the glued surfaces.
3. Curing: Placing the glued or sealed components in the air to make them cured naturally. Curing is a process that being cured from surface to the internal. The sealant will be cured at a depth of 2~4mm within 24 hours (at room temperature and 55% relative humidity), if the glue position is deeper, especially the parts that not easy to come into the air, the time that being completely cured will be longer, if the temperature is low, the curing time will also be extended. It will take more than 7 days to make 6 mm thick sealant fully cured.
Attention:
Tightening and sealing preserve the leftover sealant after the operation. Removing the cured cement at the sealing part that might happen during the preservation, it could be normally used again.
Package:
310ml cartridge, 25PCS/carton
Storage and transport
1. Kept in cool and dry place(≤ 35° C), the shelf life is 12 months when stored below 25° C.
2. Not restricted. Looking out the leakage in the process of transportation.
3. Confirming the condition of the products that out of deadline before using.

Founded in DEC. 2003, SEPUNA has been engaged in researching, manufacturing and marketing automobile sealant and adhesive for 9 years.
Since the foundation, SEPUNA Chemical has been focusing on adhesive's researching and application. Then in 2005, We acquired PUNADE technology which is from Switzerland.
Within 9 years, SEPUNA mainly develops Silicone, Polyurethane and Epoxy resin adhesives. And in the future, we will enlarge our line to Unsaturated, Natural and Acrylic Resin adhesive.
After 9 years' improvement, by the keep researching and innovation, SEPUNA is already a mature adhesive supplier with the core competitiveness.
