PRODUCT INFORMATION
Polymeric
of urethane they result of the reaction of groups Hidroxyl (OH)
of the polyols with groups isocianates (NCO) of the polish-isocianatos
or prepolymer. The castor oil possesses three groups Hidroxyl
and reacts with TDI or polish- isocianates to form crossed connections,
in the Polyurethane systems (elastomers, coatings, sealed, etc).
PROQUICIN® are isocianates aliphatic or aromatic, marketed
in natura or prepolymers with castor oil plant oil (castor oil)
with indexes of NCO free variables. They are usually used in combination
with the polyols of the line GARICIN® for the formulation
of systems Polyurethane with the following properties: Formulations
that guarantee a discharge resistance to bad weather, low absorption
of water and high isolate resistance, as well as hardness and
flexibility.
Resins with viscosities adapted so much to applications in horizontal
blockades, as in vertical (glasses of closets) and hardness that
can vary from 40 Shore "D" up to 35 Shore " D ".
Resins reentered for amendments in dry phone gel-cables , foan-skin,
connectors and headstocks not pressurized. These resins present
a variation of hardness located among 2 to 35 Shore "D",
what checks great versatility of applications.
Resins of several hardness for applications in the definitive
encapsulate of electric components or resin of the type re-entrable
for protection to the humidity in electric cables, load cells,
etc.
Due to the great versatility of these resins, it's has been obtaining
success in your application in subject places the great effort,
such as windowsills of suspensions of vehicles, bunches of springs,
etc. they also Find application as parts of components of systems
for moulded foams or integral skin in the making of supports of
arms, finishes of exchange lever, etc. The foams of prepared urethane
with PROQUICIN® gather the best density parameters, resistance
the compression and dimensional stability.
