RHOPLEXTM CS-4000

Acrylic Polymer Emulsion for Use in Concrete Sealers and Stains

Description RHOPLEX CS-4000 emulsion is a thermoplastic all-acrylic water resistant binder with an excellent resistance to water blushing. Additionally, RHOPLEX CS-4000 exhibits a great balance of early block resistance and low coalescent demand. It was specially developed for use in coatings for cementitious and other non-resilient surfaces. RHOPLEX CS-4000 emulsion can be formulated in clear as well as pigmented coatings. As with all aqueous binders, RHOPLEX CS-4000 should be carefully formulated to meet varying requirements of differing substrates and application conditions. Performance Features Coatings formulated with RHOPLEX CS-4000 offer the following features: Excellent Resistance to Water Blushing Low Water Pickup Early Block Resistance Low Coalescent Demand Good Exterior Weatherability Reduced Water Vapor Permeability Typical Properties

These properties are typical but do not constitute specifications.

The following characteristics of coatings based on RHOPLEX CS-4000 acrylic emulsion were determined in our laboratories and limited exterior exposure studies. Resistance to Water Blushing Clear films of RHOPLEX CS-4000 emulsion display excellent resistance towards water blushing in comparison to the leading commercial acrylic and styrene/acrylic emulsions. Not only do the clear films based on RHOPLEX CS4000 show a minimal amount of film blushing under both ambient (25°C) and elevated (45°C) water soak temperatures, but they also completely recover to visually clear films when the water is removed. Low Water Pickup RHOPLEX CS-4000 also has excellent resistance properties, showing low clear film water pickup (low water swelling).

Block Resistance/Low Coalescent Demand Formulated coatings based on CS-4000 emulsion show an exceptionally high degree of early block resistance, even when compared to harder polymers. Because formulators need high coalescent levels when working with hard (high Tg) polymers in order to achieve adequate film formation, RHOPLEX CS-4000 provides the formulator the ability to achieve a higher level of block resistance while lowering the VOC content of the formulation. Exterior Weatherability Based on our current exposure data, RHOPLEX CS-4000 has excellent exterior weatherability resistance. Reduced Water Vapor Permeability Coatings based on RHOPLEX CS-4000 help protect your substrate from moisture because of the low water vapor permeability of RHOPLEX CS-4000. This is an important factor to consider in the design of coatings for concrete substrates, where the existence of water and water vapor play a role in the efflorescence resistance of the finished product. Typical Applications RHOPLEX CS-4000 can be used in a variety of applications including: Primers Interior/exterior clear sealers Pigmented sealers Deck coatings Pigmented masonry coatings Curing membranes Formulation Guidelines Coalescent Since RHOPLEX CS-4000 is not a film former at room temperature, coalescing solvents are required to achieve optimal film properties. Improperly coalesced films may have fundamental flaws such as cracks, and will result in less than optimal performance. The final choice and amount of coalescent will also have a strong influence on such properties as film formation and dry time, which in turn significantly affect the properties of the coating such as block, print, water, and efflorescence resistance. We have found that the following coalescents provide adequate performance when used with CS-4000: Ethylene Glycol Butyl Ether Dipropylene Glycol N-Butyl Ether Diethylene Glycol Hexyl Ether Propylene Glycol Phenyl Ether Gives good development of water blushing resistance after 24 hours. Good coalescent to use over concrete but water blushing resistance will take longer to develop (slower evaporation rate of coalescent). Similar to Dipropylene Glycol N-Butyl Ether but can cause excessive foaming with certain application techniques. For rapid film formation (critical for curing membrane applications).

Pigmentation With RHOPLEX CS-4000, as with other coatings systems, the pigment loading and choice of pigments has a strong influence on the final durability. For applications such as vertical masonry surfaces, we recommend the maximum pigment volume concentrations (PVC) should not exceed 30%. In formulations above 30% PVC the improved water resistance properties of the CS-4000 will be reduced. Additives For many clear sealer applications, wetting agents may significantly improve the overall performance of the coating, especially over non-porous substrates. TAMOLTM 731 is the preferred dispersant for formulating pigmented coatings based on CS-4000 emulsions. This dispersant provides an excellent combination of dispersing properties with low level of water sensitivity. The use of TritonTM CF-10 can also be employed to enhance the wetting of difficult to disperse pigments. Adequate antifoaming properties can be accomplished with a variety of commercially available defoamers.
