Intumescent coatings

how to select an"APP"

In order to obtain optimum material performance, the APP need to:

　　Be dispersed properly into polymer

　　Be compatible with the polymer matrix

　　Be insoluble in water for better weathering performances

What is more, to facilitate the processing of formulations, APP need to have:

　　Good flowability

　　Good thermal stability to provide a lager processing window

To fulfill all these requirements, Exflam APP202, 203，204 provide significant

improvements in terms of material processability and performances:

¤ Coated APP benefits:

　　 Low hydrolysis

　　　Low solubility in water

　　　Less acidity

　　　Better compatibility with some polymers

　　　Better thermal stability

　　　Easier processing

　　　Less abrasion
