AVANSE™ MV-100

• Excellent corrosion resistance
• High gloss potential and excellent gloss retention
• Single acrylic resin that can be formulated for primer, midcoat, topcoat, or direct-to-metal applications. Provides a high performance system approach with a single resin
• Low coalescent demand, allowing compliance with stringent VOC regulations, formulations at 100 g/L or less provide excellent performance with the added benefit of freeze-thaw resistance
• Ambient self-crosslinking, providing excellent durability, dirt pickup resistance and solvent/chemical resistance
• Free of APEO-containing surfactants
• Excellent adhesion to various metal substrates (for example, steel, galvanized, aluminum) and other coatings (for example, alkyds)
   

• Industrial Maintenance Finishes—for example, steel structures, tanks, bridges, piping
• Commercial Architectural Finishes for Metal—for example, metal buildings, beams,doors, ceilings
• Institutional Coatings
• DIY Metal Coatings
• Transportation—for example, railcars, shipping containers, truck chassis

(¹)Dirt pickup resistance (DPUR) is measured by an accelerated method employing a simulated dirt slurry (brown iron oxide) applied to the paint surface for a prescribed time, then washing with water and wiping with cheesecloth. The ratio of initial to final Y-reflectance is used as a measure of DPUR. As a reference, MAINCOTE™ HG-54D Resin gives a ratio of 0.91 after a 1 week air cure.

Technology Behind the Benefits

• The benefits observed with coatings based on AVANSE™  MV-100 Resin are partly due to its unique role in the film formation process. With a conventional acrylic latex polymer, the final
• paint film rarely displays an optimum distribution of pigment and extender particles throughout the film.
• Both in the wet state and as the film is drying, pigment and extender particles can aggregate together and form larger agglomerates.
• Keeping the pigment particles separated in the wet state is really the function of dispersants and surfactants.
• Non-optimal dispersion leads to lower gloss and worse barrier properties than in an optimally dispersed system.
• AVANSE™  MV-100 Resin solves the problem of pigment distribution in the wet and dry states by actually forming latex-pigment composites, where the latex associates with the surface of the pigment particles. This phenomenon is depicted in Figure 1, which shows SEM micrographs of titanium dioxide particles dispersed in a conventional acrylic latex and inAVANSE™  MV-100 Resin.
• There is clearly a greater association of the AVANSE™  MV-100 Resin particles with the TiO₂ particles, such that the TiO₂ surface is partially covered with binder.
• The latex-pigment composites help to keep the pigment and extender particles separated in the wet paint and provide a more optimal distribution of pigment in the dry film, because the latex particles act as spacers between pigment particles. The result is higher gloss, better hiding, and improved barrier properties (For example, corrosion resistance). The formation of latex-pigment composites is not limited to titanium dioxide, but occurs with other mineral pigments as well. Figure 2 shows a similar situation for calcium carbonate dispersed in a conventional latex versus in AVANSE™  MV-100 Resin.
• The calcium carbonate surface appears to be completely covered by the AVANSE™  MV-100 Resin particles.
• Another key feature of AVANSE™  MV-100 Resin is its ability to self-crosslink at ambient temperatures and still maintain true one-package stability.
• The functional groups present in the resin will crosslink via both oxidative and photolytic curing mechanisms.
• Formulations based on AVANSE™  MV-100 Resin will begin to crosslink as soon as they are applied, and may require about 2 to 4 weeks until some properties have reached their maximum performance level.
• The crosslinked film provides improved dirt pickup resistance, chemical and solvent resistance, and durability.

• The typical performance demonstrated by AVANSE™ MV-100 Resin in a gloss white DTM coating formulated at 100 g/L, such as formulations MV-100-1 and MV-100-2, is shown in the Tables and Figures below.
• Although Konig hardness is slightly lower, film hardness as measured by the pencil hardness test is similar to resins with higher Tg and higher VOC requirements such as MAINCOTE™ HG-54D Resin.
• Dirt pickup resistance is also comparable to harder resins after a short air cure, and actually exceeds that of conventional resins after self-crosslinking is allowed to occur, such as after exposure to UV light. Solvent resistance, as measured by MEK double rubs, also improves significantly after a short UV exposure.
• Gloss potential is high, and durability is also excellent, as demonstrated by the gloss retention after accelerated exposure to UV-A light (Figure 3). Figure 3 compares the gloss retention of AVANSE™ MV-100 Resin with a commercial waterborne acrylic paint based on a conventional resin and formulated at a higher VOC (200 to 250 g/L).
• Corrosion resistance of coatings based on AVANSETM MV-100 Resin is excellent, as demonstrated by Figure 4, which compares it with a commercial waterborne acrylic DTM coating.

Store products in tightly closed original containers at temperatures recommended on the product label.

• Keep combustible and/or flammable products and their vapors away from heat, sparks, flames and other sources of ignition including static discharge.
• Processing or operating at temperatures near or above product flashpoint may pose a fire hazard.
• Use appropriate grounding and bonding techniques to manage static discharge hazards.
• Failure to maintain proper volume level when using immersion heaters can expose tank and solution to excessive heat resulting in a possible combustion hazard, particularly when plastic tanks are used.
