Silicon glue material is with great heat resistance and flexibility for IP67 protection housing. However, silicon glue is not resistance to chlorine erosion that could not long time be submerged under water of swimming pool. For swimming pool IP68 LED linear light solutions, we need to use top grade PU material as housing for below reasons:

-Chlorine resistance, weather resistance, not yellowing, aging for long time under water operation.

-With the features of both rubber and plastic that flexible, high strength and wear resistance.

-Tightness and no water seepage
