[UV Curing Time] How to Determine the Curing Time of UV Glue

UV glue curing time has recently called Tianhui to say how to determine the appropriate curing time of UV glue? How to set it? Today I will teach you how to determine the UV glue curing time, I hope it will be helpful to everyone. How to determine the solidification time of UV glue to determine a proper curing time for UV glue? First of all, we need an important tool, that is, radiation illumination meter. The radiation illumination meter can tell you how much light is strong at the rubber layer. Different methods depend on how you use adhesives. If glue is used between two substrates, the thickness of the rubber layer is usually 0.05 0.1mm. Tianhui's UVLED face light source, the light is generally greater than 500MW/CM2. Under this light, the solidification time of this type of glue is 2 5s. Of course, each glue indicates the curing energy it needs on the TDS. In general, the solidification time under this strong light should be less than 5s. If you seal a deeper part, it is important to curing the depth. Lotte TDS is generally measured at 50 mW/CM2. Such solidification depth is generally 1mm 2mm. Aventk's transparent glue is similar to this data. For the curing energy or curing time described by TDS, we can generally only be a reference. The most important thing is to test it in person. This is the best way to calculate the correct curing time. Set the minimum light strong on the rubber layer, you can use 50 mW/cm2. You can do it by increasing the distance of the light, until the radiation meter measured at 50 mW/cm2. After setting a fixed light strong, curing adhesive in different time. You can see the stretching strength, pressure resistance, table drying time, solidification depth, hardness or other data points climb to a maximum value and then enter the stable period. Once you determine the starting point of the steady period and add a safe range, you have a basic process. You can also set the time unchanged, change the light strong, and then dose the same data point. You can determine your process by understanding the maximum and minimum light strong and the time that requires curing glue.
