SETA® H 2959 is a urethane bisoxazolidine, serving as a latent hardener for polyisocyanates. It acts as a co-reactant for polyisocyanates in one-component polyurethane systems. This product features blocked amino and hydroxyl groups, which become active upon exposure to atmospheric moisture.

Teracure® N-33 is a medium-viscosity aliphatic polyisocyanate hardener based on Hexamethylene Diisocyanate Trimer (HDI homopolymer). N-33 is designed for use as a hardener with 2K polyurethane and polyaspartic coatings systems. Teracure® N-33 is effective with hydroxyl-functional polyesters, polyethers, and acrylics in 2K polyurethane coatings. Teracure® N-33 is soluble in esters (such as butyl acetate and propylene glycol monomethyl ether acetate); in ketones (such as acetone, methyl ethyl ketone, methyl isobutyl ketone, cyclohexanone); and aromatic hydrocarbons (such as xylene, toluene, Aromatic 100 or Solvesso 100); and mixtures of these solvents.

Teracure® N-36 is a low-viscosity aliphatic polyisocyanate hardener based on Hexamethylene DiisocyanateTrimer (HDI homopolymer). Teracure® N-36 is designed for use as a hardener with 2K polyurethane and polyaspartic coatings systems. At 100% solids, Teracure® N-36 provides a low viscosity for high-solids and solvent-free coatings formulations. Teracure® N-36 is used as the hardener in 2K coatings systems with resins such as polyurethane polyols (polyether, polyester, and acrylic) and polyaspartic amines. Teracure® N-36 is soluble in esters (such as butyl acetate and propylene glycol monomethyl ether acetate); in ketones (such as acetone, methyl ethyl ketone, methyl isobutyl ketone, cyclohexanone); and aromatic hydrocarbons (such as xylene, toluene, Aromatic 100 or Solvesso 100); and mixtures of these solvents.

Teracure® N-39 is a low-viscosity aliphatic polyisocyanate hardener based on Hexamethylene Diisocyanate Trimer (HDI homopolymer). Teracure® N-39 is designed for use as a hardener with 2K polyurethane and polyasparticcoatings systems. At 100% solids, Teracure® N-39 provides a low viscosity for high-solids and solvent-free coatings formulations. Teracure® N-39 is used as the hardener in 2K coatings systems with resins such as polyurethane polyols (polyether, polyester, and acrylic) and polyaspartic amines. Teracure® N-39 is soluble in esters (such as butyl acetate and propylene glycol monomethyl ether acetate); in ketones (such as acetone, methyl ethyl ketone, methyl isobutyl ketone, cyclohexanone); and aromatic hydrocarbons (such as xylene, toluene, Aromatic 100 or Solvesso 100); and mixtures of these solvents.
