Three major pottings refer to silicone potting rubber, epoxy potting rubber, polyurethane, use in the electronic industry, as well as electron potting glue. Experience the definition of each definition before making excellent disadvantages to understand more and more. Next, the performance of Di Monlong's technicians.
Epoxy resin is a polymer polymer, a molecular formula (C11H12O3) N, which is a class of polymers containing two or more epoxy groups in molecules. It is a polycondensation product of epoxy chloropropane to bisphenol A or polyol.

Silicone, ie silicon compound refers to a compound containing Si-C bonds, and at least one organic group is directly connected to silicon atoms. It is often used to use oxygen, sulfur, nitrogen or the like to make organic groups and silicon atoms. The connected compound is also treated as an organosilicon compound.

Polyurethane (PU) is a generally known as polyurethane, which is a polymer compound containing a repeating carbamate group. Polyurethane is reacted by a hydroxyl group of isocyanate groups and polyols, forming a polyurethane group, and a polyurethane group links a small molecule organic substance into a high molecular material of a macromolecular linear or crosslinked structure.
Polyurethane
| Contrast | Epoxy resin | Silicone | Polyurethane |
|---|---|---|---|
| odor | Big large | Small small | Small small |
| Viscosity | Higher, wear pump | Low low beneath hang down | Low low beneath hang down |
| settlement | Easy, cake | Not easy to settle | Well-dispersed |
| Well-dispersed | More serious wear on machinery | Suitable for mechanical operation | Suitable for mechanical operation |
| Curing temperature | Room temperature, medium temperature, high temperature | Usually room temperature | Room temperature |
| hardness | high height your | Low low beneath hang down | wide range |
| Adhesive | powerful strength | Low low beneath hang down | medium |
| proper temperature | -20 ~ 100 ° C | -60 ~ 200 ° C | -60 ~ 120 ° C |
| Power | Big large | Small small | middle in medium hit the mark |
| Mechanical performance | it is good good well love | generally general just like | Ok, slightly lower than epoxy |
| toughness | Poor, no shock | Good, impact resistance | General, impact resistance |
| General, impact resistance | generally general just like | excellent | generally general just like |
| Waterproof | it is good good well love | generally general just like | Good, lower than epoxy |
Through this form, it is not more intuitive to see the advantages and disadvantages between the three, and what you don't understand can contact us, you will know anything, you will provide you with a home-type intimate service.
