Viacryl SC 200/40X Epoxy resin modified acrylic resin Solutia Acrylics/ Acrylates VIACRYL® Acrylic Copolymer Resins The VIACRYL® resin family comprises three main product classes differing in the mechanism of film formation: Thermoplastic resins, basically not containing reactive groups Thermosetting resins, reacting at elevated temperature with suitable hardeners or crosslinkers like melamine, benzoguanamine, or urea resins Self-crosslinking resins, reticulating at ambient or elevated temperature Both solvent borne and water borne VIACRYL grades are available, the latter being either primary dispersions (i.e. polymerized directly in water), or secondary emulsions (i.e. emulsified in water after polymerisation has been accomplished). VIACRYL® based coatings are used solely or in combination with other resins in the following application fields: Automotive OEM basecoats, clearcoats and pigmented topcoats Car refinishing basecoats Transportation vehicle topcoats Domestic appliances High quality industrial topcoats Primers, sealers and topcoats on wood (furniture, parquet) Masonry, decorative and architectural paints Can Coating (exterior) Road marking Paint formulations based on VIACRYL® resins have desirable performance characteristics. Depending on their momomer composition outstanding properties can be achieved in terms of: Gloss and decorative appearance Hardness Mechanical and chemical resistance Outdoor durability Thermo-stability VIACRYL SC 200/40X Epoxy resin modified thermoplastic acrylic resin Air and forced drying industrial coatings with fast drying and high hardness. Specialty coatings for glass, precious metals and plastics. Viacryl SC 200/40X is mainly used for fast drying industrial paints. The dried films are noted for very high hardness and excellent resistance poperties e.g. against water and diluted acids. For air-dried systems (track-free in 15 minutes) Viacryl SC 200 can be used alone or in combination with plasticizers. Such systems compared with systems using Viacryl SC 200 as sole binder show better pigment wetting and flexibility. The use of plasticizers will, however have a negative influence on alkali resistance. The compatibility of Viacryl SC 200 with other coatings ingredients should be controlled from time to time. Stoving enamels For stoving systems Viacryl SC 200 is generally formulated with plasticizers and urea or melamine resins. The following ratios habe proven sucessful: Viacryl SC 200 : amin resin : plasticizer 70 : 15 : 15 or 65 : 15 : 20 (on solids). Compared with air drying systems such systems show after curing (e.g. 30 min/140 °C) improved flexibility, hardness, impact and chip resistance. Specialty coatings For air drying as well as stoving systems Viacryl SC 200 can be used to formulate specialty coatings with good adhesion to glass, precious metals, and various plastics such as ABS and polyphenylene oxide (PPO). Viacryl SC 200/40X is more viscous than the Viacryl grades SC 121 and 126. It may be used also for stoving enamels. Epoxy resin modified thermoplastic acrylic resin. Used as a sole binder or in combination with plasticizers and urea or melamine resins. Provides gloss, hardness, mechanical and chemical resistance, outdoor durability and thermo-stability. Offers fast drying, pigment wetting, improved flexibility, impact and chip resistance. Gives good adhesion to glass, precious metals, and various plastics such as ABS and polyphenylene oxide (PPO).
