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

Product rangeBRB CM 50 (cyclic), CM 40 (cyclic), Silicone oil 0,65 cst (linear)depending on required rate of evaporation

Silicone GlycolsTypical Properties

- Improve cleaning of oils & greases

- Reduce labour of application

D5 & PEG/PPG-18/18 Dimethicone

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
