Weld-On_® 2354 is a fast-drying clear solvent cement. Because it is water thin, it can be applied by brush, syringe, spray, and most other methods. It forms bonds by the softening and fusion of the two surfaces in contact, then cures rapidly. Within a few minutes bonded items should be of sufficient strength to handle. Relatively high strength is reached in 24 to 48 hours and continues to increase for a number of weeks. Joined material generally maintain the same physical properties, including original rigidity or flexibility.
