PUR OPTI-BASE DG 4750
OPTI-BASE is an especially transparent base coat and excellent for closed-pore and very stable surface processes. Ideally suitable as an isolation sealer and base coat with very good body under high gloss. Given its thixotropic lacquer formulation, there are no problems with applying high coat thicknesses to vertical surfaces or edges.

| Processing information | Its high thixotropy means the flow behaviour when mixing PU OPTI-BASE DG 4750 with PU Hardener DR 4034 is not comparable with that of customary furniture lacquers. The base lacquer is somewhat more viscous. The lacquer/hardener mixture therefore has to be a little more carefully amalgamated.Opened containers of PU Hardener DR 4034 have to be properly closed and made airtight after use. Slight yellowing may be evident depending on the storage period. Please conduct a trial coating and check the colour tone as necessary.Woods containing high levels of active substances, wax or oil may under certain circumstances negatively influence the adhesion and drying properties of PU OPTI-BASE. It is therefore advisable to conduct a trial coating under practical conditions to evaluate shading, adhesion and the drying process! |
| Special notes | This coating material is not suitable for application on bleached surfaces!Please note the application example concerning wet-on-wet application of DG 4750!This product must only be combined with other approved and technically suitable products when it used as a flame retardant coating material for seagoing vessels according to the latest version of SOLAS 74 Reg.
