100% Acrylic Low VOC Capable Binder for Interior/Exterior Flat to Gloss Architectural Coatings

Description RHOPLEX VSR-50 is a 100% acrylic binder designed for premium performance interior and exterior multi-substrate capable, flat to gloss Architectural Coatings, and is particularly useful in formulating paints at 50 g/l VOC. Its low coalescent demand allows the formulator to meet the 50 g/l VOC regulations with some freeze-thaw capability. VSR-50 is easy to formulate, since it is slurry compatible and has very good gloss potential. Its excellent stain removal and alkali resistance are some of its highlights for both the interior and exterior paint market. Due to its 100% acrylic composition, we expect good exterior durability, and we continue to monitor its performance at our test fences. Benefits of Paints Based on RHOPLEX VSR-50 Expanded formulation latitude to meet new VOC regulations ­ 50 g/l VOC up to 150 g/l VOC Low Coalescent demand ­ Minimum 3% required to pass Low Temperature Film Formation (40°F/70%RH) Multi-substrate Capability ­ wood, aluminum, vinyl, masonry, and composites Good Block Resistance Excellent Stain Removal Very Good Gloss Potential Excellent Slurry Compatibility Excellent Alkali and Efflorescence Resistance Exterior Durability ­ continue to monitor exposures for key properties list below: ­Dirt pick up resistance, Tint retention, Grain crack resistance, Gloss retention Masonry Sealer and Primer Capable Typical Physical Properties

These properties are typical but do not constitute specifications.

To date, we have found that 3% Texanol, based on binder solids, is an adequate level to achieve good Low Temperature Film Formation. Much of our initial work has been done in the Sheen and Semigloss formulation space, but we have found that higher levels of coalescent are necessary for exterior flat, particularly when formulating with ZnO and achieving good LTFF at 35°F and 50% Relative Humidity.

Also, we continue to screen various non-volatile coalescents to achieve the very low VOC formulating spaces for the various regulations across the country. One viable option is to blend (50/50) Texanol (or other volatile coalescent) in conjunction with a non-volatile coalescent to help achieve improved F/T, because the formulator can then add slightly more glycol to the formulation and maintain the same VOC level. In particular, we have found that a full replacement of the volatile coalescent in the High Quality Exterior Flat with zinc oxide results in excellent freeze/thaw stability. Please consult your Technical Service Representative for more details. Pigments The choice of the proper titanium dioxide grade is an important factor in achieving the desired balance of appearance and resistance properties. An advantage of RHOPLEX VSR-50 is the compatibility it offers with a wide variety of slurry titanium dioxide grades. To date, we have evaluated several manufacturers' universal slurry and dry titanium dioxides ­ Dupont 706 and 746, Kronos 4311, and Millenium 596 ­ and found no difference in performance. We expect other manufacturers' universal titanium dioxides to give similar performance. Opaque Polymer ROPAQUETM Ultra and ROPAQUE OP-96 opaque polymer are synthetic pigments which are engineered to optimize hiding in architectural coatings. These opaque polymers enable the formulator to improve properties and realize cost savings. Both of these opaque polymers can be effectively used in various formulations based on RHOPLEX VSR-50 (see attached formulations). It should be noted that the formulator needs to assess his gloss and hiding needs to determine the best level of opaque polymer to use. Dispersants and Thickeners The types and levels of pigment dispersants play an important role in attaining a desirable balance of rheology, gloss, and stability in paint formulation. In formulations using HEUR thickeners such as ACRYSOLTM RM-2020 NPR as the primary thickener, TAMOLTM 165A (hydrophobic copolymer) at a level of 0.85% (active ingredient) on dry pigment provides a good balance of overall properties. TAMOL 731A is a satisfactory alternative. If using slurry grade TiO2, you may be able to reduce the overall level of dispersant to achieve your desired properties. Cellulosic thickeners will reduce flow when used with small particle size emulsions, such as RHOPLEX VSR-50, and are not recommended for use as the primary thickener. Cellulosics can be used as co-thickeners; however, use levels should be kept to a minimum to maximize flow. If a cellulosic co-thickener is needed, greater flow can be obtained with lower molecular weight grades. Defoamer and Surfactant Based upon the formulations included in these product notes and some other lab work, we have found the following defoamers to be adequate for brush and roller application. Work continues to look at new defoamers from several manufacturers, particularly for the low VOC market. Consult your Technical Service Representative for further assistance. Tego 8030, 805 Foamaster VL BYK-024 Surfynol DF-75 Foamstar A-34 Note that spray application and/or highly tinted systems may require more or different defoamers to achieve the proper balance of properties. Several surfactants have been evaluated in our formulation work, and we have found that Triton CF-10, Triton GR7M, Tego Wet 510, Aerosol OT-75, Soprophor BSU, and BYK-348 all work well in our low VOC formulating spaces. Preservatives Formulations based on RHOPLEX VSR-50 can be effectively preserved with KATHONTM LX 1.5% microbiocide. KATHON LX 1.5% protects the paint through storage, transport, and end-use. The recommended level of addition is 25 ppm or 1.65 lb per 1000 lb paint.

Mildew Protection For exterior applications, the use of an effective paint mildewcide is recommended. Products such as ROZONETM 2000 and ROCIMATM 20 are currently being evaluated in various exposures and, thus far, look very good for mildew protection.
