Frit Ink
Frit ink screen printed glass
undergoing heat tempering

Santa Paula, CA – Abrisa Technologies screen prints glass with high durability frit ink for harsh environment applications such as marine display/cluster gauges where corrosive salt spray and fog are a continuous threat. The frit inks are also well-suited to other severe outdoor environments where organic inks may degrade and impede performance.

 

Components with frit ink pass through a tempering oven where temperatures are highly elevated and the graphics essentially become part of the glass itself. The graphics are then scratch and abrasion resistant, and retain their original appearance throughout the life of the glass. Once applied, the frit will meet operating temperatures similar to the glass substrate itself.

 

Frit ink is available in black and white as standard, with custom Pantone match colors available. The minimum glass thickness for applying frit is 3mm (0.118”). Feature resolution can be as fine as 0.305mm (0.012”).

 

According to Jacky Vel, Vice President of Sales and Marketing, “Screen printing with ceramic frit ink offers our customers many benefits. Primarily, moisture, oil, soaps, chemicals and detergents will not impact the screen print integrity, a must in many harsh or high use environments.”

ClearView™ Theater Projection Port Glass Windows 2Santa Paula, CA – Abrisa Technologies’ ClearView™ projection port window glass is fabricated using an optically clear, colorless glass with a 2-sided, multi-layer broadband anti-reflective coating, increasing transmissivity thereby ensuring a high quality, bright and sharp screen image. Transmission rate is between 98% and 99%. Optical performance is the key factor in selecting a projection port window and ClearView™ has the essential optical qualities for eye popping clarity on screen.

 

ClearView™ Theater Projection Port Glass Windows 3In addition to the AR coating, a hydrophobic coating can be applied to the port glass as well, making cleaning the view port with a non-abrasive cloth quick and easy. Efficiency of the glass is not compromised from the hydrophobic coating, while oil and dirt’s effects upon the light transmission and reflection is minimized.

 

Advanced optical technology for projection port windows became a necessity with the introduction of digital projectors. Port windows can be found in IMAX Theaters, digital cinemas, 3D projection technology, entertainment centers, home theaters, and even museum settings. The purpose of projection port windows is to allow light, contrast, and color to optimally project to the viewing screen. Regular glass absorbs colors and brightness of projected light, dulling the viewed image seen on the screen, creating image quality that can be quite poor.

 

Projection Port Windows are available in the following thicknesses:

  • 3mm or 1/8”
  • 6mm or 15/64”
  • 10mm or 25/64”
  • 12mm or 15/32”

Custom sizes with dimensions as large as 120” x 82” can be manufactured.

Chemically Strengthened Glass is Ultra-Tough


Santa Paula, CA – Abrisa Technologies’ High Ion Exchange or HIE™ glass is chemically strengthened glass that has increased strength as a result of a post-product chemical process. This process typically increases the strength of the glass by 6 to 8X that of float glass. The ion-exchange process creates a deep compression layer on the surface of the glass structure, reducing the introduction of flaws once incorporated into the end product and put into service.

 

Typically used for electronic display screens such as smartphones, laptop and tablet computers, mobile devices, touchscreens, and more, HIE™ glass provides outstanding resistance to breakage, scratches and temperature fluctuations.

 

HIE™ chemically strengthened glass advantages:

  • Improved impact resistance
  • Improved flexibility strength
  • Improved scratch resistance
  • Improved resistance to temperature changes

According to Susan Hirst, General Manager of Abrisa Technologies, “At Abrisa Technologies, we can supply the following HIE™ glass to the market; Corning® Gorilla® Glass, SCHOTT Xensation™ Cover glass, and AGC Dragontrail™.” Hirst further states, “These thin glass solutions allow Abrisa Technologies to offer a diverse portfolio of thin glass options to the display, defense, medical and industrial markets. We can service an extremely broad selection of requirements with the wide array of substrates we can provide.”
By using a thin glass such as Corning® Gorilla® Glass, SCHOTT Xensation™ Cover glass, or AGC Dragontrail™, the end product will have improved transmission, reduced weight , and reduced mounting costs as just some of the significant advantages.
Abrisa Technologies can provide customized fabrication solutions for their HIE™ glass that include the application of thin film coatings, various edge treatments, custom cutting and drilling, screen printing, Bus Bars and more.”

Abrisa Technologies’ Heat Strengthened & Tempered Glass Enhances Safety & Strength Characteristics


Santa Paula, CA – Heat strengthened glass from Abrisa Technologies is physically and thermally stronger than conventional glass, generally twice as strong as annealed glass. The safety characteristics also improve the bending strength over standard glass.

 

The heat strengthening process is utilized when a full temper of the glass substrate is not possible due to the thickness, size, or low thermal expansion rate of the glass substrate material. The heat strengthening process does not produce a full “dicing” pattern when the glass is broken, as is the case with glass that has been tempered. Fully tempered glass is typically four to six times stronger than annealed glass.

 

The primary difference between heat strengthened and heat tempered glass is the residual stress in the edge and glass surface, fully tempered glass is rated above 65 MPa (9,427 psi) in pressure resistance and heat strengthened glass is rated between 50 and 55 MPa (5801 and 7,977 psi).

 

The optical quality of the glass may be compromised to the extent that you see the tempering/quenching pattern when viewed through a polarizer. The cosmetics and flatness are also affected by the strengthening process; typically at 120/80 SD or at best 80/50 depending upon the size of the part.

 

Heat strengthening of glass is available in sizes of 168” x 96” (4,367.2 mm x 2,438.4 mm). This process can be done on glass with a minimal thickness of 1/8” (3.175 mm) and a maximum thickness of 1/2” (12.7 mm), (1” or 25.4 mm thick for smaller parts – up to 32”x 25” or 812.8 mm x 635 mm). In the heat strengthening process, the glass substrate is processed similar to a fully tempered part, except that the temperature and cycle times, along with the quenching parameters are varied.

 

Heat tempering of glass is available in sizes of 160” x 92” (4,064 mm x 2,336.8 mm). This process can be done on glass with a minimal thickness of 1/8” (3.175 mm) and a maximum thickness of 1/2” (12.7 mm), (1” thick for smaller parts – up to 30” x 24” or 762 mm x 609.6 mm). In the heat tempering process, the glass substrate is placed onto a roller table and then it goes through a furnace, heating up the glass above its annealing point up to about 720°C in some cases. The glass is then quickly cooled (quenched) with forced air drafts.

 

Typical applications for heat strengthened glass include: lighting fixture lenses, small cover lenses such as MR16s, PR20s, PR30s, and alike, where parts are not required to break into small shards based on the application.

 

Typical applications for heat tempered glass include: display cover lenses, decorative glass sheets and similar uses where the parts can be above 240°C and where public safety is crucial. If there is a high intensity light source behind the heat treated glass and the glass is in an application that the part needs to dice into small shards when broken, then the glass should be fully tempered.

 

Heat tempered and strengthened glass can also undergo various glass fabrication processes such as cutting, drilling, polishing, and edge work, however; these processes must occur prior to the strengthening or tempering process as damage and breakage can occur due to the stress in the glass as a result of the toughening process.

 

Abrisa Technologies processes comply with many industry quality standards, including ANSI, ASME, ASTM, ISO, MIL, JAN, and SAE.
