These are formulations for traffic film removers.

 

There has been an increasing demand for formulations suitable for application by high pressure spraying equipment to clean soiled surfaces ranging from domestic motor cars to heavy goods vehicles.

The pressure equipment may be found on garage forecourts, in company transport departments, or even in a growing in a growing domestic market.

To the formulator some of the following may be of interest as potential starting points in developing a suitable TFR.

TFR 1

Product	Chemical Description	% W/W
SURFAC PD38	NTA	approx 30.0%
Sodium metasilicate	Sodium metasilicate	10.0%
SURFAC LB3 or SURFAC B4	Lauryl betaine or Cocamidopropyl betaine	8.0%

STEPANATE SXS30	Sodium Xylene Sulphonate	5.0%
Caustic Liquor (47%)	Sodium hydroxide	up to 2.0% (optional)
Water	Aqua	balance

Manufacturing Procedure
The product is easily made by charging the water (40^oC Preferable) to the mixing vessel and adding the ingredients in turn whilst constantly stirring.

To increase level of foam look at increasing the level of SURFAC LB3 or use a high foaming sarcosinate SURFACARE L30.

Water	Aqua	balance

TFR 6 (Heavy Duty Cleaner)

Product	Chemical Description	% W/W
SURFACARE L30	Sodium Lauryl Sarcosinate	7.0%
SURFAC UN65/95	C9-11 Pareth-6	2.0%
Caustic Liquor (47%)	Sodium hydroxide	10.0%
Sodium metasilicate	Sodium metasilicate	5.0%
SURFAC NTA Na3 POWDER	NTA	15.0%
Water	Aqua	balance

TFR 7

Product	Chemical Description	% W/W
SURFAC NA20	Sodium Polyphosphate	28.0%
SURFAC LB3 or SURFAC B4	Lauryl betaine or Cocamidopropyl betaine	11.0%
SURFAC UN6595	C9-11 Pareth-6	1.4%
Caustic Liquor (47%)	Sodium hydroxide	2.0%
Water	Aqua	balance

TFR 8
This product is based on SURFAC K18, a potassium Polyphosphate solution instead of the Tri Sodium Salt of Nitrilo Tri acetic Acid.

Product	Chemical Description	% W/W
SURFAC K18	Potassium Polyphosphate	25.0%
Sodium metasilicate	Sodium metasilicate	8.0%
SURFAC LB3 or SURFAC B4	Lauryl betaine or Cocamidopropyl betaine	5.0%
SURFAC UN9090	C9-11 Pareth-9	2.0%
STEPANATE SXS30	Sodium Xylene Sulphonate	7.0%
Caustic Liquor (47%)	Sodium hydroxide	2.0%
Water	Aqua	51.0%

Manufacture Procedure
Dissolve the SURFAC K18 and the Sodium metasilicate in water and then add STEPANATE SXS30 and then the Caustic Liquor.

Having mixed the SURFAC LB3 and SURFAC UN90/90 together by warming in a separate vessel, and with brisk stirring. Insolubles may be removed if necessary by filtration.

TFR 9
Concentrated TFR for use at low dilutions.

Product	Chemical Description	% W/W
SURFAC PD38	NTA	45.0%
STEPANATE SXS30	Sodium Xylene Sulphonate	25.0%
VERSENOL 120	Trisodium HEDTA	5.0% approx
SURFAC UN65/95	C9-11 Pareth-6	1.0% approx
Caustic Liquor (47%)	Sodium hydroxide	4.0% circa
Water	Aqua	balance

This formula should be tested extensively to arrive at suitable dilutions depending on application.

TFR 10 (Heavy Duty Traffic Film Remover)
This formulation has a fairly high alkalinity which, coupled with the degreasant properties afforded by the surfactants should prove very effective.

Obtaining this high alkalinity by higher concentrations of Caustic Soda alone, will cause problems of paint work attack.

Product	Chemical Description	% W/W
SURFAC TSP CRYSTALS	Trisodium phosphate	8.3%
Caustic Soda (47%)	Sodium hydroxide	0.6%
STEPANATE SDBS25	Sodium dodecyl benzene sulphonate	1.5%
SURFAC ISOPROPANOL	Isopropanol	4.4%
SURFAC BG	Butyl glycol	1.3%
Water	Aqua	84.4%

General Point of Interest

In TFR's in general:

• Ammonia salts can give a better finish, too high a content of sodium salt can lead to streaking.
• A phosphonate ( BRIQUEST ADPA 60A) neutralised in situ in relatively small amounts can give excellent cleaning power to TFR 's
• Alcohol ethoxylates based on C₉-C₁₁ Alcohols (SURFAC UN65/95) are believed to give a better rinse/finish.
• If high viscosity TFR is required the addition of an anionic detergent BIOSOFT LD56E can produce a thicker product.
• VERSONOL 120 is an especially effective iron chelate and will also enhance the rinse-off property of the TFR.
