Hot bonding silicone ring glue environmental protection high temperature silicone special glue H-8620AB

H-8620AB Silicone hot geling

H-8620AB is a two-component plus-molding liquid silicone rubber glue that is heated and cured quickly, and has good adhesion to various substrates after curing. The compound has good flow and branching properties before curing; After curing, it has excellent electrical insulation and is used for silicone bonding silicone (silicone tubes, silicone strips are bonded), insulation, moisture-proof, shock-absorbing sealing or bonding of various electronic components.

Youlite brand glue H-8620How to use:

1.1 Use ratio: A:B=1:1 (weight ratio);

1.2 Weigh the material proportionally and mix evenly;

1.3 Degassing the well-mixed glue mixture under vacuum is depressurized, and then the glue is poured or applied to the place to be sealed or bonded;

1.4 Yu18After heating at 0°C for 10-15 seconds, it solidifies into silica gel.

Notes:

Glue should be stored tightly;

At a certain temperature, the curing time is related to the size of the potting part and the heat transfer efficiency of the environment.

In the process of vulcanization, it is strictly forbidden to come into contact with compounds containing sulfur, tin, arsenic, phosphorus, nitrogen, and lead, otherwise it will cause poor curing of the glue, so the compatibility test between silicone rubber and the substrate should be carried out before use.
