    Product Applications
    • Addolink®TR is used at low ratios only (about 2 - 10 % of the total amount of crosslinking agent).
    • Addolink®TR ismiscible with Addolink®B and Addolink® R at all ratios.
    • The reaction between Addolink® TR and polyisocyanates leads to three-dimensional crosslinking of the hard segments, which reduces the segregation of the hard and soft segments in the elastomer.
    • This effect can be utilized to reduce the Shore hardness of soft elastomers.
    • It also improves their resistance to swelling, but reduces their tear strength.
    • In hard elastomers it reduces shrinkage phenomena and stress cracking.

    Packaging Type
    Product Packaging

    Alu-laminated PE bags, contents 25 kg.

    Storage & Handling

    Storage Conditions
    • Addolink®TR Flakes is hygroscopic and thus to be stored in a dry place.
    • When Addolink®TR Flakes is stored in firmly closed original containers at dry conditions at approx. 25 °C, a shelf-life of 24 months from manufacturing date can be expected.
    • As Addolink® TR Flakes is crystalline at room temperature, it has to be melted before use (e. g. in an oven at 70 °C).
    • Care must be taken to melt the entire contents of the container and to homogenize them by stirring.
    • Otherwise the product ́s extremely small water content becomes locally concentrated.
    • This procedure must also be followed whenever the product is melted subsequently.
    • As mixtures of Addolink® TR Flakes and Addolink® B remain liquid at room temperature (approx. 23 °C), it is advisable to prepare a stock of them in view of the fact that they are frequently required.
    • Under no circumstances should Addolink® TR Flakes be kept liquid simply by being left in an oven indefinitely.
    • The containers should be resealed tightly after use to prevent contamination by impurities and exposure to moisture.
