BTCA for Formaldehyde-Free Textile Finishing and Functional Polymer Development

1,2,3,4-Butanetetracarboxylic Acid (BTCA) is a technically differentiated polycarboxylic acid. It is evaluated both as a formaldehyde-free crosslinker for cellulose and as a building block for high-function polymer materials.

BTCA for Formaldehyde-Free Textile Finishing and Functional Polymer Development

Durable press is a formulation and process system

BTCA can form ester crosslinks with cellulose under suitable catalyst and curing conditions, supporting anti-crease and durable-press performance without relying on conventional formaldehyde-releasing resins. Performance depends on concentration, catalyst, wet pickup, drying, curing temperature and time.

Wrinkle recovery must be balanced against tensile or tear strength, shade, hand feel and wash durability. Laboratory optimization on the buyer's fabric and finishing line is therefore essential.

The same molecule can serve advanced materials

BTCA's four carboxyl groups also make it relevant to polyimide, crosslinking and functional-polymer development. These projects may value low metal ions, controlled moisture, color and high assay differently from textile grades. The end use should be declared before comparing offers.

Define grade and trial data

Request assay, appearance, moisture, acid-value or titration method, metal-ion limits, particle size, packaging and storage. For textiles, share fiber composition, fabric weight, target wrinkle recovery, strength limits, catalyst and curing capability. For polymers, define stoichiometry, thermal target and impurity sensitivity.
