Frequently Asked Questions
DuPont Dusgon® Dust Suppression Products Dusgon 6004, 6005, 6006


1. What is Dusgon®?
Dusgon® is the brand name for a range of dust suppression agents produced and sold buy DuPont. Dusgon products can be used to control dust emissions from a variety of dusty materials. Dusgon® 6004, 6005, 6006 are surface treatment products, which mean they are normally applied to the surface of dusty material to reduce the dust emissions caused by wind and air movement. Please consult your DuPont representative to determine which Dusgon® product is suitable for your application

2. What is the composition of Dusgon® or what are they made of?
Dusgon® 6004, 6005 and 6006 are proprietry formulations so we cannot disclose the full composition. However, we can disclose the Dusgon® agents are milky white coloured aqueous polymer dispersions that contain up to 60% (by weight) synthetic polymers, wetting agents and water.

3. Does Dusgon® contain any dangerous or hazardous chemicals?
The Dusgon 6004, 6005 and 6006 products are NOT Classified as a Hazardous Good by the Australian Safety and Compensation Council (ASCC) previously National Occupational Health & Safety Commission (NOHSC). This means the Dusgon® products are NOT classified as: Flammable, Toxic, Corrosive, Carcinogenic, Mutagenic, or Reproductive toxin. Dusgon DOES NOT contain: solvents, salts, heavy metals, corrosives, acids, organochlorides, oils.
Using the Australian Dangerous Goods (ADG) Code for transportation by sea, road and rail, Dusgon® 6004, 6005 and 6006 are NOT Classified as a Dangerous Good. According to these regulations the Dusgon products does NOT require a UN number or Dangerous Goods Classification.

4. What dusty materials can Dusgon® be used on?
Dusgon® dust suppression agents can be used on a variety of dusty materials such as: soil, coal, iron ore and other mined minerals. Please consult your DuPont representative to determine if Dusgon can be used on your dusty material.

5. What applications can Dusgon® be used in?
Dusgon® agents can be used for: stockpiles, rail wagon and truck transportation applications, unsealed roads and open areas. Dusgon can also be used in other applications. Please consult your DuPont representative to determine if Dusgon can be used on your application.

6. How is Dusgon® supplied?
Dusgon® is supplied in concentrate form and diluted to the appropriate concentration before use. Dusgon® can be supplied in different size containers. Please consult your DuPont representative for the sizes available.

7. How to use or apply Dusgon®?
Dusgon® is applied by diluting the concentrate in water and spraying it over the surface of the dusty material. The treatment should be allowed to penetrate into the material. The treatment should be effective immediately. To be most effective, especially at higher wind speeds, the treatment should be allowed to dry. Please consult your DuPont representative for the appropriate dilution and application rates.

8. What does Dusgon® look like after it is applied?
The Dusgon® treatment should be milky white when it is applied but will dry to almost colourless. Dusgon® can also be coloured to suit your application. Please consult your DuPont representative if you wish to add a colouring to Dusgon®.

9. How does Dusgon® work?
Dusgon® dust suppression agents work by binding the particles together to form larger agglomerates or binding the particles into a large 3 dimensional matrix (crust) forming a protective layer on the surface of the dusty material that is exposed to wind and air movement. This stabilises the dust particles into a larger mass which makes it difficult for the particles to get airborne and increases the dust lift off wind speed.

10. What happens when it rains?
Once the treatment is dry, the Dusgon® agents are not affected by rain. The polymer will not re-dissolve or re-disperse in water.

11. Are there any OHS issues with Dusgon® ? What PPE do I need when using Dusgon®?
Although Dusgon® products are Not Hazardous or Toxic, as a guide to good safety, handling practices and occupational hygiene DuPont recommends any chemical be handled with appropriate precautions eye protection (safety glasses) and skin protection (gloves and long sleeved clothing). Please refer to the appropriate MSDS and Safe Handling Guide for more information.

12. What impact will Dusgon® have on my equipment?

The polymers in the Dusgon® agents are not known to react with metals and therefore not likely to cause corrosion in equipment made from steel, stainless steel or aluminium. However, because the final solution is normally made up by diluting the Dusgon® concentrate with water at the point of use, the quality of the water used will have the most impact on any likely corrosion. We recommend you check the quality of the water that will be used to dilute the Dusgon® concentrate.

13. What impact will Dusgon® have on my coal or iron ore?
The amount of polymer that is applied per tonne of material is very small, usually in the 1 to 10 ppm range (0.0001 to 0.001%). The polymers in Dusgon, like most other polymers, are totally combusted by 650 degrees Celsius.

14. How long will one (1) application of Dusgon® last?
The 3 dimensional matrix (crust) formed by Dusgon is not designed to withstand mechanical damage. If undamaged, one application can be effective for months until the polymer undergoes degradation under sunlight (UV).

15. How is Dusgon® affected by sunlight (UV)?
Like most polymers, Dusgon® will undergo degradation under UV light. The rate of degradation is determined by the product application rate and concentration in addition to the extent of exposure and intensity.

16. What is the storage life of Dusgon® Products?
The recommended storage life of Dusgon® products is two years

17. How should Dusgon® Products be stored?
The optimum storage temperature range is 10–35 degrees Celsius. Do not allow the product to freeze as this will damage the product. The product can withstand temperatures up to 50 degrees Celsius for short periods of time without detrimental effects.
