_____
Exolit AP 462 can be used for all applications ammonium polyphosphate is suitable for. In cases where a specific phosphorus content is required to obtain the desired effect, the lower phosphorus content of Exolit AP 462 should be compensated by increasing the amount of product added.
Exolit AP 462應(yīng)用于多磷酸銨。 假設(shè)，需要到到預(yù)期的效果就必須達(dá)到磷含量，低磷含量的Exolit AP 462就得增加用量。

Exolit AP 462 can be used advantageously in intumescent coatings where the ammonium polyphosphate is required to have extremely low water solubility and where lower heat stability at temperatures above 300 °C contributes to more rapid foaming of the coating.
Exolit AP 462適用于膨脹型防火涂料，聚磷酸銨有非常低的水溶性和在較低的熱穩(wěn)定性，當(dāng)溫度高于300℃時(shí)有助于更快速發(fā)泡。

_____
Intumescent coatings膨脹型涂料使用

On account of its low water solubility, Exolit AP 462 is particularly suitable as an ”acid donor” for intumescent coatings. Other essential components of intumescent systems include a binder, a carbon donor (e.g. pentaerythritol) and a blowing agent (e.g. melamine).
因其低水溶性，Exolit AP 462適用于膨脹型防火涂料、粘合劑和發(fā)泡劑

On exposure to flame, the intumescent coatings form a carbonaceous foam which effectively shields the underlying material from temperature increases.

遇火時(shí)，膨脹型防火涂料，能形成碳泡沫，有效地屏蔽了底層材料溫度升高。

Steel structures coated with intumescent paints can meet the requirements of fire resistance classes specified in EN, DIN, BS, ASTM and others.

鋼結(jié)構(gòu)建筑物使用膨脹型防火涂料能夠滿足EN, DIN, BS, ASTM等標(biāo)準(zhǔn)防火的要求。

The application of Exolit AP 462 based intumescent coatings on wood or plastics enables these materials to qualify for Building Material Class B (DIN EN 13501-1).

Exolit AP 462膨脹型防火涂料用于木材或塑料，符合德國(guó)建筑B級(jí)標(biāo)準(zhǔn)(DIN EN 13501-1)

Exolit AP 462 imparts a good flame-retardant effect to adhesives and sealants when it is incorporated into the base formulation at the rate of 10 - 20 %.
只需添加10 - 20 % Exolit AP 462就可以在粘合劑和密封劑中達(dá)到極佳的阻燃效果。
_____
Polyurethane foams聚胺酯泡沫

Exolit AP 462 is a suitable non-halogenated flame retardant for polyurethane foams. If handling of Exolit AP 462 as a solid is not possible we recommend the dosage of the flame retardant by preparing an Exolit AP 462/polyol-suspension. Because of the low acid number of Exolit AP 462 it is also possible to incorporate this flame retardant in an Exolit AP 462/isocyanate suspension. To prevent the solid from settling the Exolit AP 462 suspensions should be stirred or circulated by pump.
Exolit AP 462聚氨酯發(fā)泡材可作為合適的無(wú)鹵阻燃劑。由于酸值低，即可與多元醇混合，

也可直接，也可與異氰酸酯配成懸浮分散液。為了防止沉降，需要用泵攪拌。

 

_____
Other applications其它應(yīng)用

Exolit AP 462 has an excellent flame-retardant effect in cellulose-containing materials such as paper and wood products. With chipboard products the B classification according to DIN EN 13501-1 can be achieved by adding 15 - 20 % Exolit AP 462. Casting resins based on epoxy resins or unsaturated polyester resins achieve the classification UL94-V0 with Exolit AP 462. 

Exolit AP 462具有極佳的阻燃性，同樣適用于紙制品和木制品。

B級(jí)硬紙板的材料只需添加15 - 20 %就能符合DIN EN 13501-1阻燃效果。

充填樹脂（環(huán)氧樹脂或不飽和聚酯樹脂）使用Exolit AP 462同樣能符合UL94-V0阻燃效果。
