Durable low-emission binders for high quality exterior paints and plasters

Synthomer offers a broad range of binders specifically developed for high quality exterior paints and plasters. You’re sure to find a product that is ideal for your specific application, from hard polymers to softer cross-linking binders. 


Our binders for topcoat plasters and paints will deliver excellent exterior durability and a high level of dirt pick up resistance. As a result, the longer renovation intervals they enable lead to a reduced carbon footprint and lower maintenance costs. We also offer binders for exterior insulation and finish system (EIFS) applications, from panel adhesives to reinforcement plasters.

  • Low-VOC binders for environmentally-responsible long-life masonry paints, plasters and EIFS.
  • Self- and UV-cross-linkable acrylic dispersions for elastic coatings with outstanding dirt pick-up resistance.
  • Excellent weather resistance.
