Liquid insulation for wires: 7 advantages over PVC insulating tape and heat shrink
Wrapping electrical tape or shrinking in hard-to-reach places is not so easy to accomplish. This is only possible on flat areas. Relatively recently (around 2010), liquid insulation appeared. It is evenly and evenly applied to the wires, creating an integral protective film that does not conduct electricity.
Now you can freely buy liquid electrical tape in online stores (see below cost). Made from solvents and polymers. The result is a dielectric composition for convenient wire insulation.
I recently bought such a product. I saw positive reviews on the forums and wanted to try it.
The composition is available in liquid form. Sold in cans, tubes, cans (aerosol). I chose liquid duct tape in a jar.
pros
- Layer flexibility,
- Resistance to moisture, shock is higher than that of PVC electrical tape,
- Long service life,
- Not afraid of ultraviolet radiation,
- High adhesion,
- No need to use heat shrink, electrical tape, etc. isolation,
- Withstands heavy loads.
Cons that were identified by me:
- Costs more (the price is lower)
- It is inconvenient to apply. You have to pour it onto paper and then apply insulation with a stick or brush.
First you need to prepare everything. We strip the wires and use twisting or soldering. I always use twist.
In a jar, you need to mix the composition thoroughly. There is a tassel on the lid of the jar. But it was not convenient for me to use it.
Therefore, he poured the product a little on paper and applied the required amount to the wire with a wooden stick.
Then it remains to wait until the setting occurs. Initial hardening after 15-20 minutes. Full hardening (maximum strength) is achieved after 24 hours.
A big plus is that after curing, the liquid insulation remains flexible.
The result is reliable electrical, mechanical and chemical protection. It is used in auto electrician, electrical engineering, household wiring repair or household appliances.
The material does not get rough in the cold. The jar may be expensive, but it will last for a long time. Convenient thing!
