Isolante

Isolante – or isolator – does not have a direct translation into English, but combines the functions of the primer coat, barrier coat, and occasionally the sealer coat, but is not always directly interchangeable with any of them.
poliuretanici
Typically low in solids (mid 20%s), isolante are designed to:

  • Provide adhesion for the subsequent coats, acting as a primer
  • Create a barrier to stop any resins from the wood from interfering with the reaction of subsequent coats
  • Limit the absorption of the coating into the wood and minimize shrink back
  • Penetrate the surface of the wood, leaving only a limited film thickness

Isolante is not however a universal barrier coat that can be applied on any surface in order to improve the adhesion of the following coats. If not used correctly, it can cause more harm than good. It is very important to follow the Technical Data Sheets, especially in regards to the intervals between coats and mil thickness.

It is preferable not to sand IS203 before applying sealer coat. Waiting the correct amount of time to continue sealing is very important when using isolante. If the recommended time window is exceeded, we recommend sanding and applying an additional coat of IS203. It is generally only necessary to reduce the isolante when deeper penetration of the pore is necessary.

Code Catalyst Reducer & Coats When To Use When Not To Use
IS203 C204 at 1:1 Normally no, but D1010U/D1015 if necessary. From 1 to maximum 3 coats at 2-4 mils each Always use on exotic woods (teak, ebony, etc.) Always under polyester. Recommended to reduce shrink back. Never over oil based stains, or anything containing naptha, minerals spirits, etc.
IS207 C207 at 1:1 Normally no, but D1010U/D1015 if necessary. From 1 to 3 coats at 3-4 mils each Always for solvent exterior applications. Recommended for flooring. Never over oil based stains, or anything containing naptha, minerals spirits, etc. Not recommended under polyester.
IS208 C266 at 1:1 D1010U or D1015. From 1 to 2 coats at 3 to 4 mils each For interior MDF only. Makes edges and routed areas easy to sand and limits subsequent absorption and fibre raise. Never over oil based stains, or anything containing naptha, minerals spirits, etc. Never on exotic woods.
IS210 Mono-component or with C200 at up to 10% D1010U or D1015 up to 30%. From 1 to 3 coats at 2 to 4 mils each Under acrylics or where anti-yellowing is very important. Must be catalyzed if used under polyester. Generally good over metals such as brass, copper, etc. Good all-rounder. Fully test if applying over oil based stains or anything containing naptha, minerals spirits, etc. Not recommended for exotic woods.

Pre-Catalyzed Coatings

ICA is proud to recommend its line of European finishes of self-seal pre-catalyzed lacquers – the PRT100 series. Along with being easy to use, they are suitable for interior wood products requiring high levels of performance while also being economical.
