bluthane™ PU-Resins

bluthane™ PU-Resins are solutions of medium to high molecular weight polyurethane or polyurethane–polyurea with or without terminal reactive groups. bluthane™ PU-R resins can be crosslinked with polyisocyanates for 2-K coatings and adhesive applications.

bluthane™ PU-R resins when formulated as coatings provide a surface film which have excellent properties due to their high modulus, flexibility, impact strength, resistance to aqueous solutions, fuels, oils and chemicals, light, weathering and corrosion resistance.

bluthane™ PU-R resin based adhesives possess good fluidity to wet irregular surfaces, both synthetic and natural, and are excellent binders which can be cured to high molecular weight chains as a result of increased hydrogen bonding or strong covalent adhesive bonds.

Applications of bluthane™ PU-Resins

  • Special coatings for Protective, Architectural and decorative purpose.
  • Binders for magnetic media, glossy lacquers for coated textiles and leather.
  • Primary and co-resin for liquid lamination inks, PU plasticizer for NC-PU inks.
  • Adhesives for film laminations, fabric or synthetic film/sheet laminations.

FAQ’s

What is bluthane™ PU-R?

bluthane™ PU-R resins are true solutions of fully reacted polyurethane or polyurethane – polyurea in aliphatic organic solvents like ethyl acetate, methyl ethyl ketone, dimethylformamide. Solutions are available in monosolvent or mixtures, depending on the application and process requirements.

What is bluthane™ PU-R?

bluthane™ PU-R resins are true solutions of fully reacted polyurethane or polyurethane – polyurea in aliphatic organic solvents like ethyl acetate, methyl ethyl ketone, dimethylformamide. Solutions are available in monosolvent or mixtures, depending on the application and process requirements.

bluthane™ PU-R is manufactured by a special solution polymerization technique and contains primary solvents.

When and why to use bluthane™ PU-R??

bluthane™ PU-R resin solutions contain low to medium high molecular weight polyurethane, tailor-made for specific applications by careful and judicious selection of raw material.

bluthane™ PU-R is the choice when the desired application demands a polyurethane resin which cannot be made into a solid form or the desired resin cannot be handled in its original form since it would be a highly tacky resinous semi solid.< Inspite of the resin’s medium high MW the dynamic viscosities are low even at higher solid content comaperd to solutions of solid PU resins. Thanks to the versatile chemistry of PU and the special solution polymerization techniques.
