What is a Polish ?
Polish = a temporary coating that enhances and protects the
substrate to which it is applied
Enhances by cleaning and increasing gloss/color
Protects by depositing a barrier film that repels water and
also gives a degree of dirt repellency
Why are silicones used in car care?
Ease of Application-Lubricant
Polish Cleaning Ability-increase surface wettability
Ease of polishing-lubricant, less effort to polish
Gloss
Increased Colour Intensity (depth of gloss)
Surface Protection-Durability & Detergent
Resistance
Water Repellancy
Streakability-reduces “streaking” of polish
Surface Smoothness/slip-less easy for dirt to
adhere
CHARACTERISTIC
Low surface tension
Strong Si-O & Si-C bonds
High R.I:(1.375 -1.403)
Low intermolecular forces
(high chain flexibility)
Methyl groups
Low Glass Transition
BENEFIT
Spreads on most surfaces
UV, oxidative, thermal &
chemical stability
Gloss
Lubricity & high permeability,
low surface friction
Water repellency
Liquids at high molecular weight

Silicone Emulsions: benefits
Ease of Application – Streak resistance
Improved Cleaning - Low surface tension, increases surface wetting.
Allows more intimate contact between the abrasives/solvents
and surface
Polishing - Lubrication properties makes this much easier
Depth of Gloss / Color
Water repellency - Forms a lower surface tension film that
promotes water beading
Slip - Gives a smooth/lower friction surface
Silicone emulsions & oils: range
Sempure 35 & 60Water miscible 35 or 60% non-ionic emulsion of mid viscosity PDMSfor general purpose polish formulations
Sempure HV-3500 & HV-6500Water miscible 30 or 60% non-ionic emulsion of high & low viscosityPDMS blend for premium polish formulationsOptimized balance between ease of application, spreading,gloss & durability
Silicone oils 50, 350, 1000, 12.500, 60.000 cStFor customers who want to emulsify by themselvesand finetune their own emulsions
Formulation of Silicone oils
Can be formulated into
Solvent in water emulsions, normally use 50-1000 cSt PDMS
Water in solvent - can include high visc fluids
Polish formulations - use a combination of high/intermediate
viscosity fluids to optimize benefits

Volatile Fluids
Typical Properties:
Oil, alcohol solubility
Volatile
Non-greasy
Good spreadability/wetting
Leaves no residue
Colorless/odorless
Safe for most common surfaces
Applications
Replace solvent as carriers in polish
formulations (for “solventless” solvent
formulations)
Good spreading and easy to rub out
Cleaners-lift and remove dirt, low surface
tension increases surface wettability,
provides more contact between abrasives &
surface

BRB 5533Lauryl PEG/PPG 18/18 Dimethicone
Applications
Designed for formulating stable water in silicone
emulsions or emulsions in which volatile silicones
make up the oil phase
Emulsions based on silicone glycols are less greasy
than typical water in oil products
Aminofunctional Fluids for
durability
Polar amine groups which effectively anchors the product to substrate
physical attraction to negatively charged surfaces
Curable forms contain OCH3 undergoes a condensation reaction,
provides a cross-linked film on substrate
chemical adhesion & soft feel
The amino functionality enables the polish to “plate” itself on the substrate

How is durability achieved
Aminofunctional Fluids: range
BRB Sempure 373340% cationic emulsion of amino
silicone for extended durability
For maximum durability:
BRB 864 50% active solvent-based, 160 cSt,
excellent gloss, ease of application,
rub out, softer, flexible film
BRB 869100% active, 40 cSt, detergent
resistance. Harder, more brittle film,
higher durability
