BOYA TESTI– KUMAS OVMA ILE PARLATMAYA DIRENCI (BURNISH RESISTANCE-D6736)
http://www.youtube.com/watch?v=raeRhcmADhs
Interior flat paints may become burnished in areas
where clothing or upholstered furniture rub against a
wall. This rubbing may cause a smoother, glossier
surface at the contacted area, depending on the
level or type of pigments in the paint and binder
hardness. This method permits a more quantitative
estimate of burnish resistance than those using
manual rubbing techniques.
A weight of 600 g was used and the
gloss was measured after 20, 50, and
100 passes.
Elcometer ® 1720 abrasion tester
Average of 4 tests
(2 tests per panels x 2 panels)
Measure of the increase in gloss after rubbing a paint surface per ASTM #D673608. For flat paints we do not want the gloss to change.

 Ovma (asindirma) ve burnish (parlatma) direnci seramik mikrokure
yukleme miktari ve daha buyuk partukul boyutu ile gelistirilebilinir.
 Parlaklik derecesi (Gloss) ve ezilme inceligi ( Hegman gage) partikul
boyutu ile artar
 Hacimce % 5-10 iyi bir baslangic yukleme miktaridir
 Seramik mikrokure optimal yukleme miktari deneylerle tespit edilmelidir.

Conclusions
 Addition of W-410 3M™ Ceramic Microspheres considerably increases the performance of an acrylic
water-based paint, thus increasing the paint’s quality.
 Addition of 5% by volume of W-410 to a water-based acrylic paint formulation with PVC of 40%, yields the
best performance
 Higher loading of 15-20 percent by volume of W-410 3M™ ceramic microspheres is possible when
increasing the PVC content to while reducing the amount of resin, and yet still exhibits a higher
performance when compared to the baseline formulation which has no W-410.
 Viscosity did not increase dramatically when high loadings of W-410 were added to the water based paint
formulations in this study.
35

Considerations
 High loadings (10-20% by volume) of W-410 may be possible to add to a baseline water-based flat
architectural paint with PVC of 40%, if the majority of its fillers are substituted with W-410 ceramic
microspheres; as is the case of formulas DG-5 and DG-6 in this study
 Addition of W-410 Ceramic Microspheres with low to medium loading (2.5-10% volume) slightly decreases
opacity in a flat architectural paint; as compared to the baseline paint formulation with no ceramic
microspheres added and similar PVC content
 Higher loadings (10-20 percent) of W-410 will increase opacity, as the PVC increases, even if other fillers
are present in very low amounts.

Conclusions: Glass Bubbles in Architectural Paint
 Glass bubbles can increase opacity over conventional fillers and ceramic
microspheres, depending on grade.
 Stronger glass bubbles improve scrubability more than lower strength bubbles.
 Glass bubbles do not improve washability over conventional fillers.
 Glass bubbles decrease gloss more than smaller ceramic microspheres.

Cost Formulation Strategies
 3M™ Glass Bubbles and 3M™ Ceramic Microspheres can
offer the formulator alternatives to optimizing cost while
maintaining or improving opacity and durability properties
such as scrub resistance.
 Further formulation optimizations should be tested to
enhance desired properties.

Part 4: Solar reflectivity with
Glass Bubbles
68
© 2013 3M. All Rights Reserved
3M Advanced Materials Division
On the outside of a structure, solar radiation dominates. To prevent the heating of a
surface by the sun, the first step is to reflect as much of the solar radiation as possible.
Thus the first goal is to have the visible and near and IR wavelengths reflected as
completely as possible (0.28 to 2.5 μm ). The solar radiation that is not reflected is
absorbed by the surface. At that point, the absorbed energy is in the form of heat near
room temperature. (That heat can either conductively transfer into the structure, or it
can be re-emitted to the atmosphere.
Since the heat is now at near-room temperature, we need a high thermal wavelength
(2.5to 40 μm ) emissivity to effectively re-emit as much as possible back to the
atmosphere.
In summary, for an exterior surface, the goal is high solar wavelength reflectivity and
high thermal wavelength emissivity.
