Basonat TU 67 MP/X
Aromatic polyisocyanate
BASF
聚亚安酯 (PU) - 异氰酸盐
Polyurethane (PU) - Isocyanates
1-methoxy-propyl acetate-2 and xylene
Dilutable in ethyl acetate, butyl acetate and butyl glycol acetate
Insoluble in aliphatic hydrocarbons
Polyfunctional aromatic isocyanate for two-pack polyurethane
primers and top coats
Polyfunctional toluylene diisocyanate adduct, approx. 67% solution in a
1 :1 blend of 1-methoxy-propyl acetate-2 and xylene
Basonat TU 67 MP/X is suitable for crosslinking most hydroxy acrylic res-ins
such as the Macrynal ®1 SM grades, hydroxy polyester resins and other
compounds containing hydroxyl groups such as silicone resins, castor oil,
epoxy resins and phenol-formaldehyde resins.
Except for difficult substrates such as aluminium or galvanised iron,
Basonat TU 67 MP/X is used for formulating primers. Lightfastness is
mostly insufficient in top coats due to the adduct’s tendency of yellowing.
For weather-resistant top coats, often combinations of aliphatic polyiso-cyanates
such as Basonat HB 175 MP/X with Basonat TU 67 MP/X are
used.
Solution of a polyfunctional toluylene diisocyanate adduct in a blend of 1-methoxy-propyl acetate-2 and xylene. Used for two-pack polyurethane primers and top coats. Can be used for crosslinking most hydroxy acrylic resins, hydroxy polyester resins and other compounds containing hydroxyl groups such as silicone resins, castor oil, epoxy resins and phenol-formaldehyde resins. Does not suit for difficult substrates such as aluminium or galvanised iron. Can be used in combination with aliphatic polyiso-cyanates to formulate weather-resistant top coats.
