New grade of waterborne polyurethane on sale
We at Dai-ichi Kogyo Seiyaku have recently been added to our waterborne urethane resin series
SUPERFLEX 210 and begun its manufacturing and sales. This product is widely applicable toplastic coatings and paints.
SUPERFLEX 210 is a polyester-type water-dispersed polyurethane developed as a coating agent
for plastics, and it forms a very hard, very strong and transparent film. It shows excellent
adhesiveness to various plastics such as polypropylene (PP), polyethylene terephthalate (PET) andpolyethylene (PE), to which conventional products did not have enough adhesiveness. Generally,
the plastic materials used for floors and/or walls are coated for the purposes of scratch-proofing,enhancing adhesiveness to other materials and/or coloring; PP, PET and PE are more and more
employed for these purposes from the recyclability/reusability point of view. In this circumstance,
we have been receiving a lot of requests from our customers for development of such a resin thathas adequate adhesiveness to these plastics.
The market volume of the whole urethane resins is more or less around 620,000MT, and among this,the market size of waterborne urethane resins is expected to be around 20,000MT – this is expected
to grow as, in future, more and more of conventional solvent-borne urethanes should be replacedwith waterborne counterparts and also waterborne urethanes should be employed in a variety of new
application fields.
SUPERFLEX have been being sold to manufacturers of a wide range of industries, such as paint,film, adhesive, paper, fiber and artificial leather etc. Waterborne urethane resin are used as: paintfor cars, constructs, woods and plastics; coating agent for films, sheets, metals, papers and leathers;
adhesive for fibers, films and woods; binder for papers, fibers and non-woven fabrics and so on.
The application fields of environmental-friendly waterborne urethane resins are rapidly being
promoted also due to the VOC regulations.
Note:
Waterborne urethane resin – Water-dispersed polyurethane obtained by polyaddition reaction between
primary starting materials polyisocyanate and polyol, followed by introduction of hydrophilic component in
the polyurethane skeleton for stably dispersing it in water or using an additional emulsifier to make it
disperse.
The basic structure of waterborne urethane resin consists of a flexible soft segment and hard segment formedby binding units of urethane and urea bonds that have strong cohesive energy. By the balance of these twosegments, waterborne urethane resins can have all of flexibility, strength, elasticity and even highadhesiveness. In comparison with other waterborne resins such as vinyl acetate, ethylene vinyl acetate(EVA), acrylic resin, epoxy resin and synthetic rubber latex, waterborne urethane resins have extreme
strength and flexibility even when hard.
