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 and in various pack sizes.

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      


*     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.

Available in 5 litre
