- 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.

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.
