Recently a report was published online by current glass consultant and longtime industry technical expert Chris Barry discussing the unexpected breakage patterns in ceramic frit glass. To read this report please click here.

ICD High Performance Coatings and specifically our OPACI-COAT-300® Silicone Spandrel avoids the issues that Mr. Barry calls out in his study.   With the ICD product being a silicone based paint, you may have some questions, so we’ve decided to answer them here:

Top 10 OPACI-COAT-300® Questions

1. Color Availability It is possible to achieve virtually any color.

Custom color samples created in 72 hours.

2. Glass Substrates Application on a wide range of glass

substrates including:

Pyrolytic, Reflective, Annealed, Clear

and most Sputter Coated.


3. Warranty 10 year warranty by ICD.
4. Color Fastness Superior when compared to ceramic frit,

due to the use of inorganic color

pigments and dispersions.

5. Durability Excellent long term durability to UV

and humidity cycling due to silicone’s

nature.  Scratching is not a durability issue.

It is a handling issue.

Unlike ceramic frit, OPACI-COAT-300®

can be repaired on site.

6. IG Units OPACI-COAT-300® can be used in IG units.

#2 and #4 surfaces are recommended

with edge deletion required on the #2.


7. Insulation Attachment Direct attachment of insulation to

OPACI-COAT-300® is not allowed.


Compatible Materials

9. Structural Glazing Only possible in 2-sided structural glazing

applications with Dow Corning 995.

Edge deletion is required in 4-sided

structural glazing applications.

10. Vision Areas NO.  Spandrel Coatings by definition

are not designed to

be 100% opaque. (see GANA Glazing Manual)
