SILCOLAPSE®,THE ART OF FOAM CONTROL

Bluestar Silicones. Delivering Your Potential.

BLUESTAR SILICONES ANTIFOAMS

From laboratory testing to the industrial trials, our teams help you to choose the best antifoam/defoamer.

What type of foam control agent do you need? Do you need a liquid or a solid? A water free or a water based product? If aqueous what is the pH? What is the temperature of the system? What is your foaming material? Is there any regulation status requested? Which defoamer are you currently using?

Our experts have the competences and equipments to answer all these questions, to test your systems with several SILCOLAPSE® antifoams to define the optimum SILCOLAPSE® product for your application and technical needs.

Water treatment

SILCOLAPSE® defoamers are used in:■ domestic and

industrial waste water treatment.

Thanks to the harmless nature of our silicone, our customers achieve compliance with environmental standards.

Oil and gas

SILCOLAPSE® defoamers improve overall productivity in oil and gas operations:■ drilling■ extracting■ producing■ purification process■ separation process.

Our silicone formulations are classified non-toxic in aquatic environments (algae and marine fauna).

Pulp

SILCOLAPSE® antifoams are used in pulp mills for both hardwood and softwood to speed up pulp washing and drainage.

SILCOLAPSE® defoamers present:■ outstanding

knock down■ high durability in

high temperature and high alkaline foaming media

■ no deposit on cellulose fibers.

Chemical industries

SILCOLAPSE® defoamers are used to control and regulate foam in numerous processes like synthesis,distillation, transfer, filtration...

And are optimized to withstand the most hostile environments, whether very strongly acid or alkaline.

Agrochemicals

SILCOLAPSE® antifoams have been developed to control foam:■ during

manufacturing of pesticides and specialty fertilizers

■ in tank mix spray applications

■ in accordance with Agricultural (Ag) regulations.

OUR APPLICATIONS

All quality controls are made in reference standard NF T-77 112.In addition, we carry out other tests to regularly measure the effectiveness of our products with for example:

■ Fall and recycling test: NF T-73 412■ Gas bubbling test: NF T-73 413■ Shaking test: NF T-77 112■ Washing machine test for detergency■ Ross-Miles test for diesel fuel: NF M-07 075

SILCOLAPSE® : CONTROL YOUR FOAM

What is foam?Foam often results from contamination of a pure liquid by dirt, surfactants, pigments or metabolized waste. It is a dispersion of gas in a continuous phase. Foam is thermodynamically unstable but remains because of:■ the nature and proportion of surfactants

(mainly impurities)■ the viscosity of the medium.

Prevent or destroy foam■ Foam destroying agents are

called “defoamers”.■ Foam preventive substances are

known as “antifoam agents”. ■ Bubbles preventive agents are called

“deaerating” agents.

How do silicone antifoams work?A silicone antifoam droplet penetrates a bubble wall, and spreads on the liquid-gas interface causing the bubble wall to become unstable and collapse.

Benefits of foam control■ More productivity, no loss of product,

betterplant efficiency…■ Avoid product defects such as voids in inks,

paints &coating, adhesion loss, spots in textile…

■ Reduce safety hazards: liquid levels misreadings,liquid overflowing…

■ Eye irritation risks■ Environmental hazards.

1- Antifoam introduction in the film between the air bubbles

2- Silicone spreading on the film surface > Drainage

3- Film dewetting - Bridging

4- Film breaking and air release

Antifoaming and defoaming benefits of silicone compared to organic antifoams:■ Lower surface tension, greater defoaming action ■ Better resistance to heat and chemicals ■ Chemically inert, no reaction with other substances ■ Persistence, longer lasting action ■ Cost efficiency thanks to its effectiveness and persistence

at low use levels ■ Highly safe and environmentally compatible.
