OPACI-COAT-500® Granted Suitable Structural Glazing Substrate by Dow Corning

April 22, 2010 by · Leave a Comment 

After this epic test and post: “OPACI-COAT-500® Passes Extensive 4-Sided Structural Glazing Testing“ Dow Corning issued a letter to ICD on the suitability of OPACI-COAT-500® as a substrate for 4-sided structurally glazed glass applications.

This is in conjunction with Dow Corning’s 995 Silicone Structural Sealant only and it also comes with a few stipulations from :

  • Only Dow Corning 995 Silicone Structural Sealant and Dow Corning 983 SGS are acceptable for structural glazing on OpaciCoat 500 coated surfaces
  • OPACI-COAT-500® must be applied by an approved applicator per ICD (Approved Factory Fabricator or AFF)
  • Quality control methods and records from the coating application must be continuously maintained by the applicator. Dow Corning may request these at any time; but maintenance and auditing of such QC programs/records is at the discretion of ICD and their approved applicators.
  • Dow Corning structural warranties do not cover substrate failure or any loss of adhesion between the coating and the glass

Truly an exciting time for ICD and OPACI-COAT-500®.

OPACI-COAT-500® Passes Extensive 4-Sided Structural Glazing Testing

April 22, 2010 by · 1 Comment 

In a joint project with Dow Corning, our OPACI-COAT-500® was put against the ropes in a very tough round of 4-Sided Structural Glazing tests.

Testing done by Architectural Testing in Everett, WA.

A curtain wall mock-up was made with our product with the sole purpose of testing the adhesive bond of the coating to the glass and to the sealant.  Assembly was with fully tempered glass in a standard IGU and OPACI-COAT-500® on the #4 surface.  Then glazed into place with Dow Corning’s 995 structural silicone.

Evaluation was conducted in accordance with:

ASTM E 283-04, Test Method for Determining Rate of Airflow Through Exterior Windows,

Curtain Walls and Doors Under Specified Pressure Differences Across the Specimen.

ASTM E 330-02, Test Method for Structural Performance of Exterior Windows, Curtain Walls and Doors by Uniform Static Air Pressure Difference.

ASTM E 331-00, Test Method for Water Penetration of Exterior Windows, Curtain Walls and Doors by Uniform Static Air Pressure Difference.

This is where it all got very cool.

ASTM E 283 “Air Filtration”, all results were <0.01 cfm/ft2.

ASTM E 331 “Water Resistance” with 15 psf, no leakage at all.

Wait for it, this is the cool part.

ASTM E 330 “Uniform Performance”, positive and negative loads held for 10 seconds @ 155 psf, no glazing failure.  In fact, the equipment wasn’t able to produce enough load to cause failure. So they decided to cause failure and observe what happens.

A negative 100 psf load was applied, and forced breakage of the exterior lite was accomplished by striking the exposed edge of the glass. The bond of the silicone coating was unaffected.

And

A negative 50 psf load was applied, and forced breakage of the exterior lite was accomplished by firing a steel ball at the lower corner. The bond of the silicone coating was unaffected.

I’d say that’s pretty cool. :)

Here are some photos from the test as well as a great video showing the pillowing out and in of the glass, yet no failure.
