Put Parts A and B into mixing container, mix thoroughly couple of minutes to make sure that you scrape the sides and bottom of the mixing container several times. After mixing parts A and B, vacuum degassing is recommended to eliminate any entrapped air in mixture. Vacuum time should be around 5~8 minutes. 2.De-airingCan use natural deaerating and vacuum method.Natural deaerating: let the mixed glue rest for 20- 30 minutes;The vacuum deaerating: take 5-10 minutes at vacuum degree 0.09- 0.1 MPa. 3.Pouring performancePouring-Before potting, the surface of parts and the mixing container keep clean and dry.)Encapsulate the mixture into the products to finish the pouring operation. 4.Curing / Post CuringVulcanizing:Put the sealed product in room temperature and let it cure in natural condition. It needs 6-8hrs for complete curing in room temperature. If you need to speed up, you can accelerate the curing process in higher temperature. Generally, it would take 60mins to cure completely under 60oC; 30mins under 80oC and 20mins at 120oC.Our AdvantagesLiquid Silicone Rubber for HEPA Filter Air Filter Sealing Gel Silicone:1.high quality similar to global big brand2.18 months shelf life3.50-1000 duplication time decided by product sizes4.silicone non toxic, environment friendly5.fast delivery within 4-6 days6.shipment by air or by sea is available7.24h after sales service 8.professional R&D teamPackaging & ShippingLiquid Silicone Rubber for HEPA Filter Air Filter Sealing Gel Silicone:Packing : 20KG, 25KG, 200 KG per drum Shipping : by air & by sea Delivery time: within 4-6 days after your payment confirmed in our bank Storage: Storage in cool, dry places. Shelf life: 18 months with the original unopened packageCertificationsLiquid Silicone Rubber for HEPA Filter Air Filter Sealing Gel Silicone: FAQLiquid Silicone Rubber for HEPA Filter Air Filter Sealing Gel Silicone:1. What's silicone products you are making?--liquid silicone, silicone rubber, silicone oil; Due to different silicone molds, our silicone has different viscosity, and cause different hardness, density to meet the requests from client. 2. Do you offer free sample to client?--Yes, we can provide the sample for test. 3. How about the quality control in your factory?--We have professional QC team to control the quality during production. Goods will be 100% inspected before shipment. 4. How to remove the bubbles during my mould making?--After mixing liquid silicone with curing agent, please put the material into vacuum machine to take off the bubbles. 5. How to get good silicone mould to use longer time?--The best way is: #A, Please choose the right liquid silicone according to your products. #B, Don't use any silicone oil in mold making, because it can make the silicone mould become too soft to use. #C, Silicone mould can be used longer after the whole silicone mould fully cured, so it's better to wait 2 hours after mould finished. 6. Why silicone rubber add curing agent after mixing a lot of bubbles? --This is normal physical phenomena. The liquid will produce a large number of bubbles in the mixing time, so, it must pass through the vacuum exhaust bubble treatment.
