Application

--

Fire proof coatings, polyolefin, rubber and thermo-
setting plastics.

MC modification, for polyolefin, rubber and textile coating.

Organic silcone treatment for fire proof coatings.

Excellent water-
resistance property.

Epoxy resin coating, excellent water-
resistance property and more environment friendly.


Remarks:DS (Delivery specification):Inspect periodically to assure product quality. 

TD (Technical data):Random inspection. 


Characters

•Excellent thermal stability and stable viscosity. 

•Low water solubility and good immigration resistance property. 

•High polymerization degree(n≥1000)


Applications

XS-APP II Series is specially suitable for polyolefin and unsaturated resin .

1) Water based intumescent fire proof coatings :

In this system, acrylic resin works as basic resin, APP works as acid source, pentaerythritol works as charring source. When fire occurs, the thick charring layer will be formed on the surface to isolate heat, insulate oxygen and flammable gases, controls the rate of temperature rising effectively.


Fire proof coating on steel.

Dosage: 15-25%,can match the standard of DIN4102

Adhesive and sealant

Dosage: 10-25%
Epoxy resin: 25%, UL94V-0 (3.0mm)


2) Foamed PU:

We suggest to use XS-APP II 300 with the emulsion of polyol. To avoid precipitation, it needs agitation to maintain the better dispersion. The final product can match the B1 level.


3) Other applications: 

Epoxy resin

Dosage: 15-25%, UL94 V-0

Paper, Wood

DIN4102-B1

Unsaurated resin

UL94 V-0

Textile

Related standards, from 15-35%


Packing and Storage

25Kg/Bag. PP woven bag with PE film inner lining or paper-plastic bag.

Store in ventilated, dry place, avoid direct sunlight.
