we are currently renovating our kitchen and have gone with Blackwood timber doors. I had seen a sample in 2-pac (using some Imperite top coat I believe) that look exceptional and was very hard wearing unlike the traditional 1-pac lacqure that is used.
My question is that I hear people say that the 2-pac may crack when the door changes due to temperature/moisutre changes in the room ... however other's say that if applied correctly, 2-pac will not crack on a timber door.
Any advise/clarification would be greatly appreciated.
Thanks in advance.

Two pac (acid catalysed) lacquer is a very durable finish and is a lot more durable than conventional lacquer. However, if the 2 pac is applied to thickly it will crack.
Also, if you knock or ding a door with a 2 pac finish it generally leaves a whitish mark that will not polish out whereas a lacquered door can quite easily be repaired.

Depends on the type of 2pac. That which is used by the mass produced timber furniture trade is a much softer yet more flexible version of materials than those used by the kitchen industry.
Kitchen 2pac is more often than not a polyurethane based material which dries very hard and rigid, hence it's propensity to crack, particularly on timber doors.
Acid catylised laquers are normally used on veneer & craftwood as these have limited thermal movement.
Pre catylised single pack laquers are normally used on solid timber as they are softer, more flexible and allow timber to move & breathe.
Best solution for durability and cost is craftwood / mDF doors finished in Polyurethane if solid color or Pre cat over solid timber.
