Evaporator Boat – Characteristics and Applications
2-Component
- 2-Component evaporator boat is the most common product for most evaporation applications
- Particularly suitable for food package metallization process
- Good performance in AlOx metallization process
- High evaporation compared to 3-component family
2-Component Premier
- Improved corrosion resistant at high temperature
- Higher evaporation rate as it works with high temperature
- Developed for customers that need high coating thickness and high evaporation rate
3-Compontent Family
G-Comp:
- An economic option for an evaporator boat
- Can be used for both food package and capacitor metallization
- Lower evaporation coefficient than 2-Component boat
C-Comp:
- Higher AlN content than G-Component, therefore higher mechanical strength than G-comp and less creeping (bending of the boat)
- Mainly used in capacitor metallizing application, where evaporation rate is lower than food package metallization and the usage time (wet time) is much longer (up to a week or more) than in food package metallization (up to 15 hours)
3-Comp:
- Highest purity in all composition
- Perfect balance point in thermal shock/high temp mechanical, which could meet special application.
- Not used for evaporator boat application
- Use for crucible for OLED/semi-conductor, where purity and high temperature properties are critical for the application
4-Component
- Highest application temperature
- For various metals, including aluminum (Al), copper (Cu), zinc (Zn), chrome (Cr), nickel (Ni), tin* (Sn), and silver* (Ag).

Our experience has led to the development of numerous design innovations that greatly increase the standard of performance for ceramic evaporator boats. We’ve always been known for having close working relationships with customers like you. Having a close understanding of the industry requirements has led to many of our innovations.
1980s Rectangular
The original design dates back to the 1960s when all evaporator boats were clamped from the sides.
1996 ECO-VAP
Developed in 1996 to provide wetting and improved cost effectiveness, this product has found its niche where lower evaporator rates are needed and where uniformity, heat generation, and efficiency are crucial.
2000s T-VAP
- Product introduced in early 2000s has revolutionaized metallizing.
- Designed to maximize surface area for maximum evaporation while improving the temperature uniformity across the usable surface of the boat.
- Increases yield of aluminum to the substrate (lowers aluminum usage), lowers power consumption, and simplifies wetting of the surface compared to standard boats.
2005 T-VAP Plus
- Developed to deliver improved wetting during the initial heating cycle.
- The coating enables easier wetting on the desired surface of the heater.
- Improved wetting leads to more efficent evaporation and improved life of your heater.
2010 T-VAP Select
- Developed to deliver improved wettability for high evaporation rates.
- All of th edvantages of T-VAP family with additional select surface to increase wettability and increased ease of use for initial temperature adjustment.
2013 T-VAP MAX
- Significantly extends boat life
- Prevents metal overflow.
- Dramatically reduces spitting.
- Highest boat surface utilization.
- Boosts metallizing productivity.
2016 2-Comp Premier
- Increase evaporation rates when coating higher optical density.
- Up to 20% longer boat lifetime
- Less spitting due to homogeneous wetting in same boat design.
