Designed for full fill, closed-pore finishing, ICA offers a comprehensive range of products. Extremely easy to sand and yet with almost no shrinkage even in the long term. Polyesters have a significant learning curve and a very short pot life, but when used correctly, are the ultimate way to a “closed pore” finish. ICA Polyesters can be top-coated with our Polyurethane systems and many other conventional topcoats. Great for flat and shaped panels, doors, pianos, coffins, etc. CAUTION: These products require three components and should be used exactly to the manufacturer's specifications.
