First, high quality glue products, it has the high elasticity and high toughness high tensile force and adhesion stick relay and so on characteristics, use after potting products, can withstand various outdoor environment test, after one to two years or more years of time, it can keep a very stable performance, and found the glue shrinkage rate of change is very small.Of course, high-end performance in addition to special requirements, that is additional matt, thermal conductivity, flame retardant characteristics.

by glue good quality products, good quality compared with the high quality products, good quality with good elasticity, such as performance, adhesion and flexibility, tensile force stick relay can withstand various outdoor environment test, after a year or two or more years, can keep good and stable performance, and found the glue smaller shrinkage rate of change.

Finally, ordinary glue products, ordinary glue products have a certain elasticity and softness, and have a good tensile length but tensile strength and strength is not very large, adhesion Adhesion is lower than good potting glue. After one year or many years of potting, this kind of product has obvious shrinkage rate. The greater the shrinkage rate, the lower the pure material of glue and the less cost.
