Jotun Hardtop As Is A Two Component Chemically Curing Aliphatic Acrylic Polyurethane Coating That Has A High Gloss Finish With Excellent Gloss Retention. It Has Good Chemical Resistance And Can Be Used As Topcoat In Atmospheric Environments.
Jotun Hardtop As Is Recommended For Topside, Deck And Superstructure In The Marine Sector And For Offshore Environments, Refineries, Power Plants, Bridges And Buildings. Suitable For A Wide Range Of Industrial Structures, Used As A Topcoat In Pre-Qualified Norsok Systems.
Approvals And Certificates
Low Flame Spread Certificate Acording To Imo/Solas Directive. Norsok System 1, Rev.5
Additional Certificates And Approvals May Be Available On Request.
Features & Benefits
- Very Good Colour And Gloss Retention
- Very Good Chemical Resistance
- Curing At Low Temperatures
Primers
Hardtop As Will Form A Long Lasting Corrosion Protection System Together With Primers Like Barrier, Resist, Jotamastic, Penguard And Jotacote For A Wide Range Of Purposes.
Gloss And Colour Retention
Excellent Gloss And Colour Retention Makes Sure Your Property Remain Aesthetical For A Long Time.
Chemical Resistance
The Special Binder In Hardtop As Ensures Long Lasting Protection Against Different Type Of Chemicals.
Curing At Low Temperatures
Application In Cold Conditions Is Challenging, Since The Curing Mechanisms Slow Down Considerably. Hardtop As Can Be Applied Down To 0????C.
Norsok Pre-Qualification
Hardtop As Is Pre-Qualified In Several Norsok Coating Systems No. 1.
Preparation
In Order To Achieve A High Quality Finish Hardtop As Should Be Applied Directly To A Smooth, Clean And Dry Surface. Hardtop As Is A Glossy Topcoat And So Any Inperfections In The Surface Will Be Aggerated So It Is Important To Flat Back The Existing Coating Before Application. This Also Provide A Mechanical Key Which Aids Adhesion.
Hints & Tips
Use Thinner! One Of The Characteristics Of Hardtop As (Indeed Of All Two-Pack Polyurethane Paint) Is That It Can Become Tacky Quite Quickly And This Can Make It Difficult To Keep A Wet Edge - Especially If Application Is By Brush And Roller. Adding Additional Solvent Will Improve Both The Flow Out And The Final Finish. The Jotun Data Sheet States That The Thinner Required Is Thinner No. 10, However We Disagree. Thinner No. 10 Is Ideal For Use When Application Is By Air-Less Spray, But When Using Conventional Airspray Or Brush And/Or Roller We Recommend Using Hq Polyurethane Thinner. As The Name Suggests This Evaporates Much More Slowly Which Improves The Application Properties Enormously And Also Keeps The Gloss Levels At A Maximum.
Only Paint In Good Atmospheric Conditions. This May Seem Like Common Sense, But Changes In The Weather Can Have A Large Impact On Both The Application Properties Of Hardtop As And The Final Finish. The Ideal Painting Weather Is A Dry, Cool And Calm Day, But If You Find Yourselves Being Forced To Apply Hardtop As In Tricky Conditions Then:
- If It Is Hot And/Or Windy Then Hardtop As Will Dry Quickly And So It Is Even More Important To Have Some Thinner To Hand. At Higher Temperatures The Pot Life Of The Mixed Components Will Be Reduced So Only Mix Up What You Can Use In A Couple Of Hours.
- If It Is Cold The Curing Time (This Is The Length Of Time It Takes For The Chemical Reaction Between The Two Components To Occur), And The Drying Time Will Be Increased. This Means The Paint Will Be Wet And Soft For Longer.
- Avoid Painting If It Is Wet Or Very Humid. Moisture In The Air Can Prevent Hardtop As Curing Properly And Can Also Take The Edge Of The Gloss. You Must Apply The Paint Only When The Temperature Is A Minimum Of 3°C Above The Dew Point. The Dew Point Is The Temperature At Which Condensation Starts To Form And Is A Relationship Between Air Temperature And Humidity. You Can Calculate The Dew Point By Using The Table Below:
Polishing
Hardtop As Is An Acrylic Polyurethane Which Means That Runs, Inperfections And Small Scratches Can Be Carefully Repaired By Polishing. This Is Because The Heat Produced When Polishing Will Very Slightly Melt The Top Layer Of Paint And Remove Blemishes.
