New development: polyaspartatics for thick films and faster coating processes

The polyaspartics technology is a two-component-system based on polyamines as binders and crosslinked with aliphatic polyisocyanates (Desmodur® N series).

The major advantages:

• Thick, but still blisterfree films possible, so the number of coating layers can be reduced.
• Fast curing
• Low solvent content
