ResinLab® UR7024 Part A
- Chemical Family
- Polyurethanes (PU)
ResinLab® UR7024 Part A is a two-part room temperature curing polyurethane adhesive designed to impart exceptional bond strength to polycarbonate. UR7024 Clear bonds and cures quickly to a clear flexible adhesive useful in applications that require tough, impact resistant clear parts and high peel strength. UR7024 Clear can also be used for general purpose adhesive applications and esthetic assemblies. UR7024 Clear was formulated to a 1A:1B volume mix ratio for use in side-by-side dispensing cartridges and meter/mix and dispense equipment. It will reach full cure at room temperature within 24 hours at room temperature. Cure time can be accelerated by the application of heat after product has gelled. Times and temperatures from 30 minutes at 65°C to 15 minutes at 100°C are typical for small castings (less than 50 grams). Time to heat substrate must be taken into account. Cooler temperatures will extend work time and increase cure time.

- Instructions
Bring both components to room temperature prior to mixing.; Cartridge format: Mixer should be attached keeping the cartridge vertical and any air pocket purged this way. After the mixer contains material, the mixer tip can be dropped to dispense pre-bleed amount. Attach a new static mixer with each cartridge, then pre-bleed the first 3 inches of dispensed material or until a uniform color is obtained. Maintain adequate velocity during dispensing to ensure complete mixing.; Bulk format: weigh and mix parts A and B accurately and thoroughly, scraping sides of container often. Do not pour from mixing container, transfer to a new container as residual unmixed material may cause a tacky spot on the surface of the casting. Maintain adequate velocity during dispensing to ensure complete mixing.; Allow to cure undisturbed until product is fully gelled or tack-free to the touch.; Clean up uncured resin with suitable organic solvent such as MEK, acetone or other organic solvent.

- Benefits and Features
High flexibility providing high impact and peel strengths; Fast room temperature cure; Medium/low viscosity with 1:1 mix ratio for easy processing; Excellent adhesion to many plastics especially polycarbonate & acrylic; Clear bond lines
- Shelf Life Storage
6 months at 25 °C Bulk.; 12 months at 25 °C in cartridges that are foil bagged and desiccant packed.; Isocyanates are sensitive to moisture and should be kept in their original container or in a volume tank under dry nitrogen blanketing. Many isocyanates are prone to dimerization, the formation of a white precipitate. Products with minor amounts of this precipitate normally cure to full properties. Storage at 20 - 30 °C (68 °F to 86 °F) is recommended to ensure full shelf life.
