12.What is the best glue material for led strip light?Epoxy glue?PU glue?Silicon glue?
Now there 3 kinds of glue using in led strip lights.Epoxy resin glue,PU(polyurethane) glue and silicon glue.
What is the different between this 3 kinds of glue?
Epoxy resin glue is widely using in the market.Low price,good waterproof,low toxicity.
Epoxy resin glue weakness,yellow turning easy,not good for heat dissipation,not good for low temperature.If we using epoxy resin glue for led strip light,when the temperature below 0℃,it will become very tough,not flexible and easy damage.Not easy for working in low temperature area.
The PU (polyurethane) glue is better than epoxy resin glue because of its good Yellow degeneration resistance, good Low temperature resistance.
However, its price is higher as well as the toxicity.When solidify the PU glue, it will lead to some low molecular compounds,which is toxicity , it is bad for health when workers inhalation.
So it is not better to operate in workshop,That’s why it has less share on the market .
Silicon glue,it including the all advantages of PU glue and epoxy glue,which with good heat resistance,good low temperature resistance,good yellow degeneration resistance and low toxicity .The glue will not change yellow for use a long time and also good smell .
Now most of suppliers are use this silicon glue for led strip light,and more high quality led productions, which are think highly of by the customers.
