Tank filter sealing Liquid tank glue is mainly used for potting and sealing of liquid tank filters, high efficiency filters, liquid tank air conditioner filters, liquid tank purification filters, etc.
Product serial number
Product description

1. Product characteristics and application
HY9405# is a low-viscosity , viscous, gel-like transparent two-component addition type silicone potting compound. It can be cured at room temperature or by heating. The higher the temperature, the faster the curing. This product does not produce any by-products in the curing reaction, and can be applied to the surfaces of PC (Poly-carbonate) , PP , ABS , PVC and other materials and metals. Suitable for insulation, waterproofing and fixing of electronic accessories . Fully compliant with EU ROHS directive requirements.

2. Typical use 

-Slot type high efficiency filter

-Potting of electronic circuit boards, etc.


Third, the use of technology:

1.     Before mixing, firstly mix components A and B in their respective containers thoroughly.

2.     When mixing, the weight ratio of A component: B component = 1 : 1 should be observed .

3.  HY9405# can be defoamed as needed. The mixed solution A and B can be stirred evenly and put into a vacuum container, defoamed at 0.08MPa for 5 minutes , and it can be used for perfusion .

4.     The corresponding curing time should be maintained above the temperature given in the technical parameter table before and after curing. If the application thickness is thick, the curing time may exceed. Room temperature or heat curing is acceptable. The curing speed of the adhesive is affected by the curing temperature. It takes a long time to cure in winter. It is recommended to use heating to cure, 20 minutes at 80 ~ 100 , and about 8 hours at room temperature .


 The following substances may hinder the curing of this product, or cause uncured phenomena, so it is best to apply it after a simple experimental verification. If necessary, the application area needs to be cleaned.

..incompletely cured condensed silicone..amine - cured epoxy
resin..solder flux
