Jotun Hardtop Optima is a two-pack isocyanate-free polysiloxane topcoat with outstanding gloss and colour retention. It is available in a wide range of colours.
Hardtop Optima should be applied over a suitable epoxy primer where a durable high grade finish is required in an aggressive atmospheric environment.
Advantages of Hardtop Optima:
* Isocyanate free, so fewer health issues during application
* Good brush and roller characteristics - much easier to keep a wet edge than with 2 pack polyurethanes
* Excellent gloss retention
* Excellent colour stability
* Very good abrasion resistance
* High volume solids results in a thick coating AND good coverage
* Long pot life once mixed - typically 50% longer than with polyurethanes
If thinners are to be used, either Thinners 7 (xylene) or Thinners 17 (epoxy) may be used. We recommend Thinners 17 (epoxy) as it has a slower rate of evaporation, which improves the wet edge characteristics of the paint.
