Coated Quartz Glass Plates for UV Curing Equipment -TOQUARTZ®
Properties of Coated Quartz Glass Plates
TOQUARTZ® specialized coated quartz glass plates combine exceptional material properties with precision manufacturing to deliver components that excel in UV curing applications. Each plate is meticulously produced to ensure optimal performance in your UV curing equipment.
Heat Resistance
TOQUARTZ® UV curing quartz plates can withstand continuous operation at 1100°C and short-term exposure up to 1450°C without deformation. With a low thermal expansion coefficient, they can endure rapid temperature changes without cracking, making them ideal for high-intensity UV curing applications.
Optical Transmission
TOQUARTZ® specialized coating technology allows UV light to pass through while effectively blocking infrared radiation. This unique property enables optimal curing without heat damage, with visible light transmission exceeding 93% and UV transmission above 80%, maximizing curing efficiency while preventing thermal damage to sensitive materials.
Chemical Resistance
Highly resistant to almost all acids and chemicals (except hydrofluoric acid), our quartz plates maintain their chemical stability even at elevated temperatures. This makes them ideal for UV curing equipment operating in environments where chemical exposure may occur, such as industrial painting facilities or PCB manufacturing.

Usage Guidelines for Coated Quartz Glass Plates
Handling & Installation
- Handle with care to avoid impacts or drops that could cause breakage.
- For high-temperature applications, clean thoroughly before use and wear thin gloves during handling.
- Avoid direct hand contact to prevent fingerprints and contamination that could affect performance.
Chemical Compatibility
- Avoid contact with hydrofluoric acid (HF), which can etch and damage quartz.
- At high temperatures, strictly avoid contact with alkaline substances like water glass, asbestos, or potassium/sodium compounds.
- Contact with alkaline materials at high temperatures will significantly reduce performance.
Temperature Considerations
- Do not exceed the maximum operating temperature (1100°C for continuous use, 1450°C for short-term).
- Exceeding temperature limits can cause crystallization or deformation of the quartz plate.
- Consider thermal expansion in mounting designs to prevent stress fractures.
Cleaning & Maintenance
- Clean with appropriate optical-grade solvents and lint-free wipes using gentle motions.
- Regularly inspect for coating degradation, scratches, or contamination that could affect performance.
- Store in clean, dry conditions with appropriate protective packaging when not in use.

FAQ
Q: What coating options are available for UV equipment applications?
A: TOQUARTZ® offers several coating options for UV applications: Anti-Reflection (AR) coatings to maximize transmission at specific wavelengths, UV-enhancement coatings optimized for 185nm, 254nm, or other UV wavelengths, IR-blocking coatings to filter unwanted heat, and dichroic coatings for selective wavelength transmission. Custom coating designs are available to meet specific spectral requirements.
Q: Can you match specific UV transmission requirements for my application?
A: Yes, TOQUARTZ® can optimize transmission for specific UV wavelengths through material selection and specialized coatings. For applications requiring high transmission at 185nm or 254nm (common in UV sterilization), we recommend JGS-1 material with appropriate UV-enhancement coatings. We can provide transmission curves and test reports to verify performance for your specific wavelength requirements.
Q: Do you offer engineering support for integrating quartz plates into our equipment?
A: Yes, TOQUARTZ® engineering team provides technical support for integrating our products into your equipment. We can review your designs and provide recommendations for mounting methods, sealing techniques, and thermal management to maximize performance and longevity. For complex applications, we offer more comprehensive design collaboration services to ensure optimal integration with your systems.
Q: Can you match a coating specification from another supplier?
A: Yes, we can match coating specifications from other suppliers in most cases. Providing us with the spectral performance data or a sample for analysis allows us to develop an equivalent coating. For direct replacements, we can analyze your existing components and develop coatings that match or exceed their performance. This service is particularly valuable for customers facing supply chain disruptions or seeking more competitive pricing.
Q: What is the maximum operating temperature for coated quartz glass plates?
A: The base quartz material can withstand continuous operation at 1100°C and short-term exposure up to 1450°C. However, coatings typically have lower temperature limits. Standard AR coatings can typically withstand temperatures up to 300-500°C, while specialized high-temperature coatings may operate up to 800°C. We provide specific temperature ratings for each coating type to ensure compatibility with your application.
