silicone encapsulant 

                    HM-6402L A/B

Product description

Two parts potting adhesive, with 1.41 refractive index. Normally used as potting adhesive in LED corn light . with high transparency, excellent releasing the bubble , short curing period,   good mold unloading property and excellent resistance to high and low temperature.

 silicone encapsulant

Parameter

Guide

1.     Mix two parts with ratio of 1:1, operating in the dry and dustless

2.     Use dispenser to mix evenly then fluid dispensing. Or put it into 100Pa vacuum container and release the bubble at room temperature.

3.      Spray coating mold  release agent on the mold before fluid dispensing, before gel injection, warm the LED corn light in the 150℃ for over 30 minutes to remove dampness . fluid dispensing quickly before the LED corn light absorb moisture again

4.     Put the sample at room temperature for 30 minutes until no bubble.

5.     Put it in the  80℃ oven  and bake for 30 minutes , then turn the heat up to 150℃ immediately. It will cured completely. Then release the mold.

6.      Put the un-used silicone in the clean airtight container, and put them on the worktable then use it conveniently.

Remark

1.     HM-6402A/B is additional organic silicon. Temperature has a great influence on the curing speed.  We should pay attention to the stirring speed and time when deploying, Control the temperature under 35 ℃

2.     HM-6402A/B is additional organic silicon elastomer. Avoid Contact with N,P,S, alkyne, diene, pb,  Sn, Cd,Hg, and  heavy metals .In case it hardens  incompletely or not , clear the surface before potting

3.     Different operations will lead to different results .such as bubble,  interlayer, degumming, crack glue. Please avoid the causing factors, or consult relevant personnel.

4.     Vacuum equipment is an open system and don't be mixed with epoxy resin. in case it cured and hinder, the ideal is to set up a production line of silicon.

5.     Need to use the silicon mixing container and stir bar,  avoid contact silicon with rubber gloves .

6.     Because the silicon is uneasy to release the bubble,  when the gas and the bubble engulfed in the silicon during the injection, please heating at the begining of the room temperature to release the bubble.

7.     Not good bonding, the reason is incompletely vulcanize, and has not been effective joint with the adhesive. In order to improve the adhesive strength We can raise the  temperature or prolong bake time .

8.     Because we can not control the condition and the way of our products, the technical data should not be as a substitute for user testing. If you doubt the material will inhibit curing, we advise you to do a small compliance test to make sure the certain particular application fit or not, or consulting our company technical staff to get help.

Storage

1.     Stay in cool and shady place. 6 months after the date of manufacture. After shelf life, we can keep using after several  all technical indicators met the  specification .

2.     These products don't belong to dangerous goods, so they can be transported as normal chemicals. 

3.     A & B must be sealed in  dry place, but be careful of Leakage.
