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

▶ 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

•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.
