WHAT IS KHADI BINDER?
Khadi print paste is available in the market as a white paste ready for printing. The exact composition of khadi paste is a trade secret but it is essentially prepared by the incorporation of titanium dioxide as white pigment. The content of titanium dioxide could be as high as 25-30%. This paste is used for producing white prints on white fabric or on dyed fabric. Because of high concentration of titanium dioxide and binder the prints are harsh. Harshness of the prints can be compensated by using plasticized binders which produce soft film on polymerization.
NOTE: If pigment colour is incorporated in the khadi paste colour print effect can be obtained against colour background imitating colour discharge effects

P R I N T I N G GUIDELINES
SHOULD WE OR SHOULD WE NOT USE CATALYSTS? Since Stretch Khadi Binder is a self cross linking acrylic emulsion, Catalysts is not necessary to achieve film durability where curing conditions are optimum. But where curing conditions are less than optimum, an acid or lateen acid catalyst is recommended . The use of Di- Ammonium as catalyst is recommended typicaly due to anionic emulsifying system of our Stretch Khadi Binder. OPTIMUM drying and CURING CONDITIONS Prints are dried at 80oC to 90oC on a drying cylinder range or on hot glue and subsequently cured at 140oC -150oC for 3 – 5 minutes
