CCS Bonder Paste, Chem/Rad Resistant

 This is a high-modulus, two-component epoxy paste adhesive formulated for chemical and radiation resistant bonding. It is used to bond precast concrete segments to concrete or steel, and for bonding concrete, masonry, stone, and steel to each other. Additionally, it is suitable for filling spalls, gaps, and cracks where high chemical and/or radiation resistance is needed.

 The material consists of Part A (resin) and Part B (hardener) in a 2:1 volume ratio. It can be extended with dried silica sand (1:1 volume ratio) for specific applications requiring reduced heat generation or thicker applications. It can be applied without sag up to 1/4 inch thick.

 This epoxy paste is applied in structural bonding of concrete or steel, filling voids, and surface leveling. It can be used on horizontal, vertical, and overhead surfaces. It is particularly suited for environments where chemical and radiation resistance are critical.
