TECHNICAL INFORMATION
Etherified methylol melamine crosslinking agent
GENERAL PROPERTIES
- Free formaldehyde contents is lower than conventional methylol melamine
crossliking.
- Gives a stiff handle on woven and knitted fabric made from natural and stnthetic
fibres.
- Is used alone or combination with reactants used for the shrink resistant finish of textile made from
- natural and regenerated cellulose.
- Is wash fast fixing.
- Gives boil wash fast effects on cotton.
- Gves a full handle on cotton and blends with synthetic
fibres.
- Improving the shrink resistant of cotton and blends with synthetic
fibres.
- Improving the shrink resistant of cotton and increases the resilience, also the shape retention.
- Can be used for binding of mineral fibrous webs, especially of glass fibrous webs.

SPECIAL ADVICE
- A small quantity of acetic acid is recommended to add into the bath to prevent the solution turns to turbid appearance.
PROCESSING
The required quantity of Durapret MF is diluted in cold water.
The application is done at the usual temperatures, curing is done depending from field of application and catalyst at temperatures between 130° - 170°C for 5 minutes to 15 seconds.
