The New development of JLS Ammonium Polyphosphate Surface Treatment without

Formaldehyde

1. Why JLS develop new grade APP104 series

2. JLS-APP104 series characteristic

3. In the textile water-proof is important:

Good water-proof ≠Good fire resistance effect

4. Difference between JLS-APP104 series grade product

5. How to use JLS-APP104 series

1. Why JLS develop new grade APP104 series

•New grade APP104 series for Textiles FR coating ▶ The limit of formaldehyde is the globality tendency.

▶The textile coating must pass water-proof testing generally. For specific standard, it must pass hot water-proof and steam testing generally.

▶ APP and other grade treated by ordinary method : →Difficult to pass water-proof testing →No to pass hot water-proof and steam testing

▶ APP modified by common melamine- formaldehyde treatment

→ Formaldehyde releasing

→ Some influnence in the efficiency of flame resistance

• Customary surface treatment problem

Based on APP(II, n>1000)Better water-proof, formaldehyde freeFor water base

▶ JLS-APP 104 → Common water-proof, formaldehyde free

▶ JLS-APP 104 S and JLS-APP 104 W

→ More high water-proof, maybe can pass hot water-proof and steam testing,

formaldehyde free

▶ JLS-104MF → For hot water-proof and steam testing, formaldehyde

(NH4PO3)n → (HPO3) m

2. Melamine transformation:C3N6H6 →NH3↑ + C

3. Carbon donor transformation:RCH2OH + (HPO3) m → C+H2O

•If using APP treated by MF resin in your formulation, the content of formaldehyde must go beyond the limit of standard.

(According to material formaldehyde test method)

★ In textile, there are many standard and regulate

•Domestic textile→Need dash test →DS 5852•Automobile →No need dash test →SMV SS302•Tennis →Need more strict dash test →CPAI 84 (USA)•Clothes →Need more strict dash test →CFR 1615/1616 (USA)•Plaything →No need dash test →EN 71(Eur.)•And so on

5.How do JLS-APP104 series used

★ Conclusion

1. JLS-APP104S/W :The balance of good water-proof and Formaldehyde free2. Water-solubility →JLS-APP104S and JLS-APP104W are better than JLS-

APP104, JLS-APP104MF is the best3. Flowability →JLS-APP104MF>JLS-APP104S>JLS-APP104W>JLS-APP104

→dispersive 4. Formaldehyde test → JLS-APP104MF have Formaldehyde, but can resist on

hot water and steam.
