UV Gaskets and Seals
New, UV and visible light curable Form-In-Place gaskets, (FIP/CIP), are available from Panacol-USA that possess flexibility, resiliency, moisture resistance, and low compression set. High viscosity gel gaskets will maintain their profile from dispense through cure.
With performance that surpasses traditional die-cut gaskets, Panacol-USA gasket materials are dispensed as flowable liquids or non-migrating gels, exactly where a gasket is required. The material can be cured (hardened) in seconds with broad spectrum UV lamps or LED systems (365nm/405nm) as part of a continuous in-line production process. These gasket materials are ideally dispensed using industry standard, programmable robotic equipment. Automation maximizes processing speed and ensures consistent gasket profile and cure. Adjustments for new product geometries can be made in minutes without the added costs, delays, and down-time waiting for new (die-cut) tooling. Gaskets can be formed on-the-spot for the most complex component configurations.
Panacol-USA’s Stay-In-Place gasket technology produces gasket materials that adhere to the surfaces they are cured upon, allowing immediate handling and continuous production. In the event that future component disassembly and gasket replacement becomes necessary, the gasket can be removed without difficulty. A wide variety of gasket materials are available to meet desired functional performance. Typical performance properties include high resistance to moisture, low shrinkage, ability to withstand repeated thermal cycling, high cohesive strength, and surfaces that range from tack-free to sticky (similar to a Pressure Sensitive Adhesive).
These products cure in seconds when exposed to UV/Visible light (320-460nm), with at least 50 mW/cm2 intensity. Panacol-USA UV gaskets are also available that cure with LED system producing either 365nm or 405nm wavelengths.

Please contact Panacol-USA to confirm your product selection and to secure additional application assistance, including samples and process recommendations. In the event that these standard products do not satisfactorily address your performance requirements, Panacol-USA will investigate other solutions that include development of gasket material that is specifically tailored to the complexity of your application.
