Coating Epoxy Museum Grade
A specialty, crystal-clear epoxy system engineered for unpigmented glass-like coatings on artwork, designer pieces, laminates, and restorative surfaces - where long-term clarity truly matters.
Why choose Coating Epoxy Museum Grade:
-
Advanced anti-yellowing chemistry
Synthetically stabilized epoxy backbone resists UV-initiated yellowing and oxidation far beyond what conventional “UV-additive” systems can achieve.
-
True glass-like look
The mixed system’s refractive index closely matches high-grade borosilicate glass, delivering exceptional depth, gloss, and optical clarity.
-
Thin-film flow & air release
Optimized low-to-high mixed viscosity technology self-levels in thin layers and releases micro-bubbles efficiently for a flawless surface.
-
Extended open time, coating resin without the use of harmful accelerators
A controlled, additive-free cure schedule gives you the best-in-class workable time to coat - without dangerous accelerators or harsh reactive diluents.
-
Durable, blush-free finish
Cures to a hard, high-gloss surface suitable for display pieces and restoration work.
What makes this resin “museum grade”:
The core advantage is anti-yellowing stability. Unlike standard, widely available epoxy resins that rely solely on UV absorbers, this system uses synthetically modified resin chemistry to greatly reduce the pathways that lead to yellowing (UV exposure, oxidation, and thermal aging). The result is long-term clarity in coats where even a slight tint shift is noticeable.
In addition, its glass-like optical behaviour means light bends through a cured film much as it would through glass, producing maximum depth and a clean, glass-like look for clear coats.
How it is used:
-
Ideal conditions: Work at 23–25 °C in a clean, dust-controlled area.
-
Mixing: Mix resin and hardener by weight for 4-7 minutes, scraping sides and avoiding excessive air entrapment.
-
Induction & degassing (do not apply yet): After mixing, let the resin stand for ~1.5 hours to initiate the reaction and allow the remaining bubbles to escape for uncompromised clarity.
-
Application window (~2 hours): This is your coating time. Early in the window the mix is low–medium viscosity for maximum flow and levelling; later in the window viscosity rises, which helps with edge control and reduced runs/sags. Apply by using plastic/silicone tools like a v-notched spreader.
-
Recommended coat thickness: 0.6 - 1.3 mm (25 - 50 mil) per layer.
-
Multi-coat builds / recoat: Recoat within 24 - 48 hours. If you are past the window, do a light scuff-sand with 400-grit sandpaper and clean before recoating.
-
Surface preparation: Seal porous substrates first to prevent outgassing; apply in a dust-controlled environment.
