MIX

 

Mix two parts with ratio of 10:1, simplify the matching process, after mix well, use vacuum pump to release the bubble. The rubber should less than two-thirds of the container, in case the rubber overflow during release the bubble

 

Pouring and curing

 

Curing to elastomer within 4-8h at room temperature.  Decrease temperature can extend the vulcanization time.  Adjust the ratio of A & B can accelerate or decelerate the curing speed

 

Storage and Shelf life

keep sealing under 30C  , 6 months after the date of manufacture


REMARK                                                                       

Completely cured sealant is non-toxic, but do not directly contact with eyes or kids. Should keep ventilate when applying. We suggest that before applying, customer had better have a test to make sure our sealant can highly meet your demand.

; $ tf8;: 88 dana;color:black'>4.If require mat effect,pls add the C component, and only after 24-48h of potting, the mat effect comes out.Relatively,higher temperature can accelerate the mat effect, but keep in mind, should be lower than 50C.


5. Color depends on customer’s requirement.

Test

We suggest that customers should test this product before application and see if it could meet the demand.

Shelf life

Store under 30C and stay sealed

Shelf life of component A and B is 12 months after the date of manufacture.

Note: This product is subject to curing temperature, the  temperature is higher, the operation and full curing time will be shorter.

workmanship

Mixing A,B parts according to proportion A:B=10:1 on the basis of weight or volume until evenly. Suggest to stir A and B part respectively before mixing them to make it uniform distribution. Then dispense the adhesive on the potting position. If need high-thermal conductivity vacuum  deaeration

 is necessary otherwise no need. It can be cured at room temperature or by heating. But it is featured of room temperature curing, there is summertime and wintertime types, the two types are sthe same except for the operation time.

Note:

This silicon rubber is vulcanized by platinum catalys, the nitrogen, sulfur, phoshor and rgano-tin compound material may hinder its vulcanization, so please clean the rosin on the PCB and use the soldering tin with low lead content.

Packaging:40kg/set

Storage period :sealed under 30C, the A,B parts shelf life are 9 nine months after production. Thereare sediments come after 3 months,please mix it thorough eveness before using.
