Water based Polyurethane Dispersions make excellent adhesives. Suitable water based polyurethane adhesive grades range in hardness from very soft and tacky to non-tacky heat sealable grades.
These products are uncompounded water based polyurethane resins which may be suitable for some applications as supplied. However, they may require the addition of additives such as wetting agents, defoamers, thickeners, and or other additives to optimize them for your specific application. We would be happy to work with you to help customize these water based polyurethanes for your requirements.
Premium grade, medium soft for heat seal applications on many substrates at 190-200F.
This premium grade, medium soft, co-solvent free water based polyurethane dispersion dries to a clear tack-free film. The UD-104 is an excellent candidate for water based polyurethane heat seal adhesive application as well as lamination adhesives applications. It will heat seal at 190 to 200 degrees F and it has very good adhesion to a wide range of substrates.
Very soft, dried to a clear, soft film with excellent resistance to hydrolysis and microbial attack. For in-line heat sealing
This very soft, co-solvent free, water based polyurethane dispersion dries to a clear soft film. The UD-108 is an excellent candidate for water based polyurethane heat seal adhesive applications if the heat sealing is done in line so that product blocking is not a consideration as well as lamination adhesives applications. UD-108 has excellent resistance to hydrolysis and microbial attack and it has very good adhesion to a wide range of substrates.
Extremely soft, dries to a clear film with high residual tack. Good when heat sealing is not an option
This extremely soft, water based polyurethane dispersion dries to a clear film with a high degree of residual tack. The UD-125 is an excellent candidate for water based polyurethane lamination adhesives applications. The pressure sensitive properties of this water based polyurethane dispersion make it a good choice for applications where heat sealing is not an option because of substrate heat resistance limitations or processing constraints. It has excellent adhesion to a wide range of substrates including some typically difficult to stick substrates. The UD-125 does contain NMP co-solvent.
Dries to semi-clear film, low residual tack. For heat seal and lamination applications
This soft water based polyurethane dispersion dries to a semi-clear film with almost no residual tack. The UD-301 is an excellent candidate for water based polyurethane heat seal adhesive application as well as lamination adhesives applications. It will heat seal at 190 to 200 degrees F and it has very good adhesion to a wide range of substrates. It is more economical and softer than the UD-104 but does contain NMP co-solvent.
This economical, very soft, co-solvent free, water based polyurethane dispersion dries to a clear soft film. The UD-302 is a good candidate for various water based polyurethane adhesive applications. It has excellent resistance to hydrolysis and microbial attack like the UD-108 but does not adhere to as wide a range of substrates.
