DIT-70 is currently used as a polyisocyanate hardener / crosslinker raw material in steel coating and automotive refinish coating formulations.
Steel Coatings
DIT-70 can be considered for polyurethane coating formulations used on fabricated steel and related industrial steel substrates. Final suitability should be evaluated in the customer’s actual formulation, substrate preparation and application process.
Automotive Refinish
DIT-70 can be considered for automotive refinish coating formulations where an IPDI trimer polyisocyanate crosslinker matches the formulation requirement. Product-specific formulation validation is recommended before commercial use.
When to Consider DIT-70
Consider DIT-70 when evaluating an IPDI trimer polyisocyanate hardener for steel coating or automotive refinish coating formulations.
Confirmed Selection Signals
