Specifications are based on Dongsen’s current approved product data source. Final suitability should be validated in the customer’s actual formulation and process conditions.
BI-70C can be considered for textile and fabric bonding or lamination formulations where a water-based blocked polyisocyanate crosslinker is required.
Dongsen supplies BI-70C as a raw-material crosslinker, not as a finished textile adhesive.
Final suitability should be validated in the customer’s actual formulation and process conditions.
Consider BI-70C when evaluating a water-based blocked polyisocyanate crosslinker for textile and fabric bonding or lamination formulations.
Its HDI Trimer technology classification, anionic water-dispersible form and 120°C deblocking temperature are confirmed selection parameters. Refer to the Technical Data tab for the complete specification and validate suitability against the customer’s formulation and thermal process window.
BI-70D, BI-70E and BI-35C may also be reviewed as related grades within the confirmed Textile / Fabric application direction. These are selection directions only and do not imply comparative performance.
For grade-selection support, provide Dongsen with the relevant formulation and process requirements for technical review.
For current BI-70C technical documentation and document-status confirmation, contact Dongsen technical support.
