Agents FIGURE 1 | Case Study 1: Matting performance in an acrylic resin (5% solids on solids). FIGURE 2 | Case Study 2: Matting performance in an acrylic/PU lacquer for wood coating (3% solids on solids). Application Areas and Processing Instructions Typical application areas include: (a) wood coatings, particularly furniture and parquet lacquers; and (b) decorative and industrial coatings. Michem Guard 349 and 350 can be post-added with gentle mixing to ensure a homogeneous distribution. Selection of the appropriate matting agent depends on the dry film thickness. Optimum matting performances are obtained with dispersion particle size closely matched to the required dry film thickness. A level addition of 3% solids on solids is recommended to start with. Case Studies Both Michem Guard 349 and 350 have been successfully incorporated in various high-gloss paints and varnishes. Their performance in reducing the level of gloss is illustrated in Figures 1-3. High-quality, haze-free films were obtained in the case studies described in the figures. In all cases, the gloss was measured at 60° on a Leneta chart. In all the case studies shown in Figures 1-3, performances of Michem Guard 349 and Michem Guard 350 were compared to a well-established matting agent considered as being a market reference. Samples of Michem Guard 349 or 350 can be obtained via the website, www.michem.com, or through the local agent and distributor network indicated on the website.
