    Description

    The light-color TPUA-E33D (similar to RFE) is an established, universal curing agent for adhesive based on hydroxyl polyurethane, natural and synthetic rubber. TPUA-E33D can be used instead of TPUA-13-F25G . RFE is even more satisfactory from the aspect of industrial hygiene.

      

    Application

    After the addition of TPUA-E33D, the ready-to-use double-component adhesive should be applied within a period (pot life) which is determined not only by its content of rubber but also by the other ingredients of the formulation (e.g. resins, antioxidants, solvents, etc.) If the adhesive is not used within this period, it may become increasingly difficult to apply and its viscosity increases rapidly until irreversible gelling ultimately occurs.

      

    Typical Properties

    Chemical composition

    Contains 27% thiophosphoric-tris-(p-isocyanato-phenyl ester) and 73% ethyl acetate

    Appearance

    Clear yellow to brownish liquid

    NCO content, % by weight

    7.2±0.2

    Solubility

    Soluble in acetone, toluene and methyl ethyl ketone and aromatic solvents

    Storage stability

    Reacts readily with moisture; for the best performance it should be kept dry and stored at temperatures between 5oC and 32℃

     

    Compatibility With Solvents

    TPUA-E33D can be diluted with anhydrous and alcohol-free ethyl acetate dichloropropane, trichloroethylene, acetone, methyl ethyl ketone, toluene, and other solvents. The addition of relatively large proportions of aliphatic hydrocarbons can cause turbidity; but the solution of natural rubber in aliphatic hydrocarbons shows good compatibility with TPUA-E33D, in the absence of other solvents.

     

     

    Performance

    TPUA-E33D shows good bonding strength in PVC with much plasticizer, SBR with plenty of oil, coating leather, silk and so on.
