Masurf SP-135 and Masurf SP-245 are specially modified polymers optimized
for Surface Protection of bathroom, shower and related surfaces subject
to soap-film and similar soils. Masurf SP-135 and Masurf SP-245 treated
surfaces repel soap-film, soap-scum, and bathroom grime build-up by
creating a highly effective invisible soil barrier. Masurf SP-135
and Masurf SP-245 treatment leaves surfaces shiny with no dulling
residue while effectively repelling soils to keep bathroom surfaces
cleaner longer.
Masurf SP-135 and Masurf SP-245 offer formulators the option of developing
specific products for a range of applications. For Surface Protection,
prepare a 1-5% aqueous solution of Masurf SP-135, adjust ionic strength
with acid, alkali or salt to just the limits of solubility to maximize
deposition onto treatment surfaces. For Surface Protection with Cleaning,
prepare a 5% aqueous solution of Masurf SP-245 with acid (i.e. citric
acid at 5%) or alkali (i.e. 50% sodium hydroxide solution at 0.1%).

SP-245 Product Data Sheet. |

| Soap-Film Preparation and Demonstration
for Masurf SP-135/SP-245 Surface Protectors |
| Soap-Film
Preparation (1000 ml) |
| Part A |
Disperse 5 grams of Dial Antibacterial bar
soap (yellow bar) shavings into 800 grams of deionized
water. With continued stirring, heat mixture to 40°C to
completely dissolve soap. |
| Part B |
In a separate beaker, dissolve 0.48 grams
MgCl2 and 0.53 grams CaCl2 with stirring into 198.98 grams
of deionized water. |
| Part C |
Slowly add Part B to Part A with stirring
for a 0.5% soap emulsion in 300ppm hard water. Transfer
the mixture to a spray bottle. Please note that the emulsion
will slowly separate upon standing, so shake before each
use. |

| Demonstration |
Thoroughly clean a new
4 ¼ x 4 ¼ inch black glossy ceramic tile. Rinse residual detergent
or cleaning solution thoroughly with isopropyl alcohol followed by
tap water. Tap water should run instantly off the tile.
Wipe half of the tile with a paper towel soaked with solutions/formulations
of SP-135/SP-245. Rinse excess SP-135/SP-245 with tap water, being
careful to not rinse excess SP-135/SP-245 onto the control (untreated)
side. When the demonstration tile is properly prepared, water will
cling to the SP-135/SP-245 treated side and will run instantly off
the control side.
Allow the rinsed tile to dry, then spray (10-15 sprays) with the soap-film
mixture prepared above with the tile positioned with the treated and
control sides vertically (side by side, rather than top and bottom).
Rinse and repeat application of soap-film mixture until a noticeable
amount of soap-film has accumulated on the control side. Allow the
tile to dry for a more pronounced demonstration of results.
To demonstrate the cleaning performance of Masurf SP-135/SP-245 cleaning
formulations, apply a liberal amount of Masurf SP-135/SP-245 cleaning
formulation to the control (soap-film soiled) side of the tile. Allow
several seconds for complete penetration of the Masurf SP-135/SP-245
cleaning formulation, then rinse. Repeat soiling steps above to demonstrate
the Surface Protection properties of the cleaned surface. |
