Content
This presentation is in two parts:
o First part: an ‘AGBB-friendly’ self-emulsifying
hardener for 2K waterborne PU coatings
o Second part: a low viscosity polyisocyanate
hardener, as a reactive diluent and internal
flexibiliser in solvent-free polyurea coatings

• System to evaluate / restrict VOC in building products
• Total VOC of interest but limits set (LCI / NIK) for individual
components also
• Low LCI / NIK is bad, (no value is even worse), high is good*
• Solvents often included in 2K WB PU to help: • Compatibility / miscibility
• Optimise drying and open time
• Film formation
• Improve and film appearance
• Vencorex fast drying Easaqua grades use IPDI trimer, which
requires solvent in order to be incorporated, also can give
‘ready to use’ grades

XD 870 was also tested by Worlee together with some of their resin grades.
With WorléeCryl A 1241 W and WorléeCryl A 2441 W, XD 870 gave the
same high level of performance as seen with XD 803.
Results with WorléeCryl A 2441 W:

We have tested XD 870 also in one concrete flooring formulation.
We have no comparative data but the XD 870 gave rise to some
promising results:
