- Polyisocyanates:
Species possessing free isocyanate groups and derived from monomeric
isocyanates either by directly linking these monomeric units (a
homopolymer) or by reacting these monomers with di- or
poly-functional alcohols or amines (a copolymer).
- For highly elastic
coatings with resistance to accelerated and outdoor weathering;
combination with suitable polyisocyanates allows variation of the
elasticity using the same polyol mill base Polyurethanes based on
aliphatic polyisocyanates are well known for their outstanding
properties, especially for their exceptional resistance to
weathering.
- Polyisocyanates -
Quantifying polyisocyanates is much more complex.There are currently
three potential approaches used to quantify and express
concentrations of polyisocyanates; the pure product mass, the NCO
group concentration or mass, and the monomer equivalent mass.
- Polyisocyanate which
is also insoluble in water.
- Isocyanates are
chemicals containing the highly reactive isocyanate group. When
there are two or more isocyanate groups on a molecule (diisocyanates
or polyisocyanates), they can link together with certain other
molecules to form long chained polymers called polyurethanes.
- Polyisocyanates may
elicit four major types of reactions
in the lower respiratory tract:
1. Toxic bronchitis with asthma, also called reactive airways
dysfunction syndrome (RADS), caused by very high exposure levels.
2. Bronchial asthma caused by sensitization to diisocyanates, where
very low exposure levels may provoke symptoms.
3. Accelerated decline in FEV1
4. Extrinsic allergic alveolitis like e.g. in “bathtub refinisher´s
lung”
