DEAP-3600 in SNOLAB is a Dark matter Experiment with 3600 kg liquid Argon using Pulse shape discrimination. The detector consists of a 1.7m-diameter Acrylic Vessel (AV) bonded with 255 acrylic light guides. The inner surface of AV is coated with the wavelength shifter to allow 255 PMTs to register argon scintillation light.
It is expected to reach a sensitivity of 10^{-46} CM^2 for a 100 GeV WIMP. An overview of DEAP-3600 will be given, especially with focus on light guide bonding process. Besides, low-background control of acrylics in the JUNO project will also be discussed.
