OPACI-COAT-300® is ICD’s flagship water-based silicone glass coating engineered specifically for spandrel glass, interior wall cladding, and other opaque architectural glass applications. As a 1K (single-component) silicone elastomer system, it provides a durable, flexible, and chemically resistant opaque film that adheres to virtually all architectural glass types. The system is known for its excellent color uniformity, long-term performance, and ultra-low VOC formulation, making it suitable for high-performance commercial and institutional projects where sustainability, consistency, and lifecycle durability are critical.
The coating offers an unlimited opaque color palette with precise batch-to-batch matching, supported by ICD’s controlled manufacturing and certification programs. Because the coating is applied by trained/approved fabricators, projects benefit from repeatable application quality, controlled film build, and reliable visual results across large façades. Its adhesion and flexibility characteristics help maintain coating integrity under thermal cycling, while its 100% opaque formulation makes it a widely adopted alternative to ceramic frit, often providing improved thermal stress mitigation and aesthetic control.

What Is OPACI-COAT-300®
A water-based silicone spandrel and interior wall cladding glass coating for fully opaque, cavity-backed applications. It offers a wide range of colors, does not weaken the glass substrate, and provides fallout resistance when applied appropriately.
How can samples of OPACI-COAT-300®
OPACI-COAT-300® coated glass samples can be requested through the ICD website, where you can specify the type of glass and the desired color. This allows for a physical evaluation to ensure the color and finish meet the project’s specifications. Contact ICD with any sample questions.
Who can purchase OPACI-COAT-300®
Approved Factory Fabricators (AFF’s) are the glass processing companies who are certified to make beautiful backpainted glass products like spandrel and wall cladding with OPACI-COAT-300® water-based silicone glass coating. AFF’s stretch across the globe creating a large sourcing network for anyone looking to purchase OPACI-COAT-300® coated glass. Each AFF is certified yearly to ensure year-over-year consistency in material handling, application, and their ability to produce excellent silicone coated glass. AFF’s are the only businesses allowed to purchase and apply OPACI-COAT-300®. Contact ICD if interested in becoming an AFF, or to learn about the AFF’s located in your region.
What are the color options for OPACI-COAT 300®
OPACI-COAT-300® comes in 16 standard industry colors and offers an extensive range of custom colors, matching over 26,000 shades from major color systems like Pantone, RAL, Sherwin Williams, and Benjamin Moore. This flexibility ensures that virtually any desired shade can be achieved for specific project requirements. Interested in a coated glass sample? Contact ICD.
Where can OPACI-COAT 300® coated glass be installed?
OPACI-COAT-300® was developed and is tested to withstand the temperature and humidity extremes of spandrel glass in facade building envelopes.
Which glass surfaces can OPACI-COAT-300® be applied to?
On monolithic glass, OPACI-COAT-300® is applied to surface 2. On an IGU, OPACI-COAT-300® can be applied to surface 2 or surface 4. Surface 2 is used for a more bold up-front color look, but will need to be edge deleted for the primary seal to adhere directly to the glass. Surface 4 is used for a look of depth and is the recommended surface when using facade visual harmonization suggested colors. See FAQ about low-e coatings if low-e coatings are present.
Can OPACI-COAT 300® be used with low-emissivity (low-e)
OPACI-COAT-300® is compatible to be applied on top of some hardcoat (pyrolytic) low-e coatings. Contact ICD for compatibility test results. OPACI-COAT-300® cannot be applied on top of softcoat low-e coatings and cannot share an IGU airspace with softcoat low-e coatings. If a softcoat low-e coating is being utilized on surface 2 or 3 of an IGU, OPACI-COAT-300® needs to be applied on surface 4.
Can OPACI-COAT 300® can be used on diffrent types of glass?
Yes, it is compatible with all types of glass, including annealed, heat-strengthened, and tempered glass. The product enhances the glass’s integrity. In the event of 6mm tempered glass breakage, if OPACI-COAT-300® was applied at 13 mil WFT it will provide fallout resistance by holding 6mm tempered glass broken pieces in place until it can be replaced.
Is OPACI-COAT 300® environmentally friendly?
OPACI-COAT-300® is lead-free, ultra-low in VOCs, and does not contain heavy metals, making it a greener choice for glass coating applications. It also aligns with the Build America, Buy America (BABA) Act, confirming its manufacture in the United States under stringent environmental and labor standards.
How does OPACI-COAT 300® compare with frit?
OPACI-COAT-300® offers several advantages over ceramic frit, including better environmental profiles, a broader color palette, and the ability to strengthen glass rather than weaken it. It also has a unique property of fallout resistance, which keeps 6mm tempered glass pieces from falling out of their frame in case of breakage.
