EpoxySet Inc. UB-50
- Chemical Family
- Urethanes
UB-50 is a clear, two-part urethane resin system, which combines good handling characteristics with excellent cured properties. Its low viscosity allows good flowability and air release. The cured elastomer has excellent bond to metals, ceramics, and many plastics used in medical industry such as acrylic, polycarbonate, PVC etc. They also have excellent water resistance, and are exceptionally resistant to thermal shock. They can be used as an adhesive or for potting, casting and encapsulating applications.

- Use instructions
1. Weigh each 50 grams of PART-A to 100 grams of PART-B. 2. Mix until uniform. Scrape the sides and bottom of container repeatedly during mixing. 3. Vacuum de-airs for 3-5 minutes. 4. Apply to clean bonding surfaces and cure as recommended to achieve the desired properties. 5. Typical cured properties were determined using recommended cure schedule. 6. Some difference in properties may occur with the alternate or other cure schedules.. Thaw premixed frozen adhesive at room temperature for 5-10 minutes. Dispense adhesive and cure at recommended schedules.
