Specifications are based on Dongsen’s current approved product data source.
Textile / Fabric
BI-35C is a water-based blocked HDI trimer crosslinker with a confirmed application direction for Textile / Fabric formulations and related textile-processing contexts.
Dongsen supplies BI-35C as an upstream raw-material crosslinker rather than a finished textile coating or adhesive product.
Application boundary: this confirmed mapping does not establish a fixed dosage, formulation ratio, resin compatibility, curing profile, bake profile, bond strength, wash resistance, durability or other customer-system result. Final suitability should be validated in the customer’s actual formulation and process conditions.
When to Consider BI-35C
Consider BI-35C when screening a water-based, water-soluble blocked HDI trimer crosslinker for Textile / Fabric formulations and when a 120°C deblocking-temperature grade is relevant to the formulation-selection process.
Confirmed Selection Signals
BI-35C is a water-based, water-soluble anionic blocked HDI trimer with a confirmed 120°C deblocking-temperature parameter. Refer to the Technical Data tab for the complete confirmed specification set.
Application Fit
Textile / Fabric is a confirmed application direction for BI-35C. Final suitability should be validated in the customer’s actual formulation and process conditions.
Important Selection Note
The 120°C value is the confirmed deblocking-temperature parameter for BI-35C. It should not be interpreted as a universal customer bake temperature or curing schedule.
When to Contact Dongsen
Contact Dongsen for grade-selection support when evaluating BI-35C in a specific textile or fabric formulation and production process.
What application direction is confirmed for BI-35C?
Textile / Fabric is a confirmed application direction for BI-35C. The confirmation establishes the application direction but does not define a universal dosage, formulation, resin compatibility, curing profile or finished-system performance.
What does the 120°C deblocking temperature mean for grade selection?
120°C is the confirmed deblocking-temperature parameter for BI-35C. It can be used as a grade-selection parameter, but it should not be treated as a universal customer bake temperature or curing schedule.
Is a public Technical Data Sheet available for BI-35C?
An approved public TDS for BI-35C is not available in the current reviewed evidence set. Please use the technical-support route below to request current product information and grade-selection support.
