Hardtop Optima 5L


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.

Available in 5 litre tins

We currently have some stock of Hardtop Optima which has gone out of date and can be sold at very good prices. Please contact the office on 01285 862132 if you are interested.
