3 SDS-2 Dust Suppressant
Technical Data Sheet
1. PRODUCT DESCRIPTION
3M™ SDS-2 Dust Suppressant is a biodegradable,
concentrated water management tool, for use wherever
dust suppression is required, such as:
 Mine haul roads
 Stockpiles
 Construction Sites
 Unsealed roads
 Parking Areas
 Longwall mining
3M™ SDS-2 Dust Suppressant is a water based solution
which includes a blend of wetting agents. The wetting
agents are designed to accelerate water penetration and
increase water retention of the road surface.
3M™ SDS-2 Dust Suppressant, when used according to
instructions, enables a reduction in water consumed for
dust suppression purposes. Repeated applications have a
cumulative effect, maintaining subsoil moisture content for
long periods, depending on soil types, traffic and weather
conditions. 3M™ SDS-2 Dust Suppressant has been
formulated to lower water surface tension, allowing it to
penetrate and effectively knockdown dust particles
A recommended dilution rate of 0.1% means a 20 litre pail
of 3M™ SDS-2 Dust Suppressant is added to 20,000 litres
of water. Higher dilution rates can be applied, dependant
upon site conditions. Consult your 3M representative.
Advantages of using 3M™ SDS-2 Dust Suppressant
 Reduces water consumption at low dilutions
 Biodegradable
 Saves equipment and labour costs
 No disruption to production schedule
 Uses existing equipment
 Mixes easily with water
 No rinsing of tanker needed

3. RECOMMENDED APPLICATION METHOD
3M™ SDS-2 Dust Suppressant can be applied by water
trucks equipped with rotary pump and spray manifold or
by water cannon.
4. MIXING INSTRUCTIONS
It is recommended that 3M™ SDS-2 Dust Suppressant is
added directly from the pail to the water vessel, however a
dosing pump may be used if desired. To avoid excessive
foaming, 3M™ SDS-2 Dust Suppressant should be added to
the water vessel after the water has been loaded. The product
self mixes during truck movement.
5. APPLICATION
Nominal dilution is 0.1% in water, at a recommended
maximum coverage of 0.5 litres per square metre per
application pass. Diluted product should be applied as often as
required to control dust. It is not necessary to stop traffic to
allow application; however care should be taken to avoid
applying excessive solution at road corners. For stock piles
and other low traffic zones, it is recommended that 3M™
SDS-2 Dust Suppressant is applied at 0.2% dilution.
Higher application rates and dilution levels may be required
for a high temperature or windy environment, according to the
conditions at individual sites. Discuss this with your 3M
representative or 3M Technical Service.

7. ENVIRONMENTAL
All ingredients of 3M™ SDS-2 Dust Suppressant have been
assessed as biodegradable. It is unlikely to have significant
effects on wastewater treatment organisms or aquatic life;
however measures should be taken to avoid release of any
chemical additives directly into waterways.
8. HANDLING and STORAGE
When diluted, 3M SDS-2 Dust Suppressant does not present
any unusual hazards. The diluted product is not classified
as hazardous according to the criteria of National Exposure
Standards Australia. When applying the diluted product, good
industrial hygiene practices should be used to minimize any
exposure to potential skin, eye or respiratory contact.
3M™ SDS-2 Dust Suppressant is stable when stored under
normal warehouse conditions, for 5 years from manufacture.
Do not freeze. Keep container tightly closed when not in use.
9. PACKAGING
3M™ SDS-2 Dust Suppressant is packaged in recyclable 20
litre, 200 litre & 1000 litre containers.
