Installation Instructions

RTV2 Liquid Silicone White Color LED PCB Board Silicone for Electronic Potting Rubber Silicone:

1.Measuring & mixing

Before you begin, accurately weigh Part A and Part B. 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-airing

Can 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 performance

Pouring-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 Curing

Vulcanizing: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.

FAQ

RTV2 Liquid Silicone White Color LED PCB Board Silicone for Electronic Potting Rubber 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.
