The two part polyurethane resin and equipment can be used for casting, doming, coating, encapsulating and potting numerous applications including domed decals, solar panels, encapsulation, composite construction and coating substrates. Our two-part polyurethane resin and equipment can be used for casting, doming, coating, encapsulating and potting numerous applications including domed decals, solar panels, encapsulation, composite construction and coating substrates. Our resins are automotive grade, clear, weather resistant and non-yellowing. Epoxy resin can also be used for doming, encapsulation and coating porous substrates. The polyurethane doming resin is used on pressure sensitive vinyl’s, metal, plastic, rubber, glass, carbon fiber, solar panels and many other medias to help protect labels, decals, signs, covers, circuitry, etc. Our two-part resin is optically clear and will not yellow outdoors. Our mercury free resin has been successfully used for over 20 years in outdoor applications with minimal degradation. It has the same weathering properties as mercury catalyzed systems as well as the same gel times and cure times.
Non-Yellowing Epoxy like Resin
We offer an epoxy like resin that will not yellow outdoors. It is a non-yellowing resin that is glass hard like epoxy and is not moisture sensitive. It has a fast cure time with less thermal coefficient of expansion than epoxy.
Flow-Stop
Flow-stop is an ink that stops urethanes from flowing beyond its printed boarder. By printing a 1/8” border around what requires urethane, flow-stop will hold the urethane to that area. Flow-stop can be silk screened on to most vinyl, mylars, metal, etc.
Dispensing
Polyurethane Domed Labels - High quality automotive grade polyurethane doming resins give domed labels, decals, emblems and nameplates a protective 3D clear domed surface. Our computer controlled doming equipment is designed for fast turnaround with scripting capability.
UV-Resistant Polyurethane Resin
We offer the best clear polyurethane resin available anywhere. Our UV-resistant polyurethane is a non-yellowing polyurethane product that comes in flexible or rigid formulas. Both are weather-resistant for a minimum of four years. You'll also find solar resin, used for coating solar panels, as well as potting resin, used for coating and encapsulating electronic components. Polyurethane resins are available in either low viscosity or high viscosity, the latter being used for producing higher domes. Whether you're producing polyurethane over vinyl decals or doing specialized casting, coating or encapsulating, we have the quality products you need for the job.

Regulatory & Compliance
- Certifications & Compliance
- Compliance
Our mercury free resin has been used for over 20 years and is REACH, ROHS and EPA compliant.
Safety & Health
- Safety
Chemline Z-8500 is for industrial use only. Avoid contact with eyes and skin. Do not inhale or ingest. Contains aliphatic diisocyanate and polymeric isocyanates.
Storage & Handling
- Storage
Both materials must be protected from moisture. Storage temperatures should be ambient. In storage, containers should be tightly closed since this material is moisture sensitive. Material should be warmed to 90-110°F prior to use. With proper storage practices, the shelf life of Chemline Z-8500 is 6 months or more.
