Ottopol SX-30 is a self-crosslinking acrylic emulsion for flexo or gravure printed films. This translucent emulsion polymer exhibits resistance to alkalis and solvents, such as diluted alcohol solutions. It has excellent adhesion to substrates and provides excellent resolubility properties when applied.

Ottopol SX-50 is a self-crosslinking acrylic emulsion with good adhesion to non-porous surfaces. This product has alkali resistance and exceptionally good adhesion to plastic films, foils, and other metallic surfaces. Due to the internal cross-linking mechanism, it also has improved block and scuff resistance.

Ottopol SX-75 is a self-crosslinking acrylic emulsion with good gloss for flexo and gravure printing. This product has alkali resistance and exceptionally good adhesion to vinyl and other non-porous substrates. Due to the internal cross-linking mechanism, it also has improved block and scuff resistance.

Ottopol KX-99 is a hydroxyl-functional cationic acrylic solution polymer that crosslinks with polyisocyanates and epoxy silanes at room temperature. With the combination of polyisocyanate and epoxy silane, the fastest and most resistant coating can be formulated. We recommend a maximum of 20% epoxy silane and 20% polyisocyanate based on solids. This product undergoes ambient curing very quickly, and in less than one hour the film will have water resistance. Allowing the film to cure for two hours will result in a film that has over 100 double rubs of acetone resistance. Detergents and cleaners will not remove this film, and the final dried film resists staining.

Ottopol SX-100 is a self-crosslinking acrylic emulsion for alkali resistance. This product has exceptionally good adhesion to substrates and is non-film-forming for glossy flexo and gravure inks. Due to the internal cross-linking mechanism, it also has improved block and scuff resistance.

Ottopol 510-28 is an anionic hydroxyl functional acrylic solution polymer that crosslinks with melamine and isocyanates. This product has excellent salt, fog, and solvent resistance.

Ottopol 523 is a hard acrylic emulsion with hydroxyl functionality. This functionality allows crosslinks with melamine and isocyanates for excellent solvent resistance. Formulations using aziridine will require a plasticizer or coalescent solvent to aid in the film formation of the dried coating. The use of aziridine will result in a short pot life and will cross-link at room temperature. Formulations using melamine and PTSA (Para-Toluene Sulfonic Acid) are stable for a minimum of thirty days. The starting formulation requires a web temperature of 180°F to activate the cross-linking of the resins. An increase in PTSA will lower the temperature required to activate cross-linking, but larger amounts of PTSA will increase the hardness of the dry film. There are no plasticizers or coalescent aids required for film formation when using a melamine resin with this product.

Ottopol SF-45 is a unique acrylic polymer that results in a high-density, cross-linked polymer upon drying at room temperature. Where solvent resistance is required, many coatings can be derived from this polymer. It is mainly used as a coating for wood or wooden furniture.
