Product Description

Condensation type silicone sealant
A/B HT-9918BK
A/B HT-9918BK is a double component condensation type silicone sealing material, can be cured at room temperature, curing process of release of ethanol molecules, PC (Poly-carbonate), ABS, PVC, PP, copper and other materials will not produce corrosion. Good adhesion to most electronic parts (PE, PP).
A typical use: protection, indoor and outdoor LED display potting, encapsulating module of electronic components
Two, technical parameters

Thermal conductivity W/ (M - K) 0.3
The range of applications of high-end LED screen.
The biggest characteristic is good, can be deep curing
Three, the use of technology:
3.1 before mixing, group A need to use the appropriate mix of manual or mechanical components, B should be in a sealed state by fully shake
Device, then use.
3.2 when you need to adhere to the application materials, please confirm whether you can attach, and then apply.
3.3 mixed, the general weight ratio is A:B = 10:1, if need to change the proportion, to respond to the mixed proportion of change
Simple experiment. The average amount of B is more, the curing time is shorter, the operation time is shorter.
3.4 in general, filling thickness below 20mm can be naturally defoamed, without further deaeration. If the filling thickness, surface
And may be bubbles and pinholes, therefore, should put the mixture into a vacuum vessel, in 700mmHg to debubble
Less 5 minutes.
3.5 environmental temperature is higher, the curing is faster, the operation time is shorter. Generally do not recommend heating curing, so as to avoid the surface and internal pinhole
Or bubble, affecting the appearance and sealing performance.
Four, packaging specifications: 22KG/ sets (A 20kg/ 2kg/, B plastic bucket)
Five, storage and transportation:
5.1 store in a cool dry place, storage period of 9 months (25 C).
5.2 such products are not dangerous goods, can be transported by the general chemical.
5.3 colloid A, B components are required to be sealed to preserve, be careful in the process of transport leakage!
5.4 products over the period of storage should be confirmed to have no exception after the use of.
The above performance data is the typical data measured in the laboratory environment of the temperature 25, humidity 70%, only for the use of the reference, and can not guarantee the full data in a specific environment, please customers in the use of experimental data as the standard.
