Smooth-On PC-3™ Laboratory Table Top Cement is a two-component, black epoxy resin compound designed to join, bond and caulk sections of laboratory counters and tables. This epoxy resin cement is heavily filled and will adhere to vertical surfaces without sagging. It cures at room temperature with extremely low shrinkage.
Features
PC-3™ contains no volatile organic compounds (VOC’s) or solvents. It resists solvents and dilute acids and bonds strongly to natural and artificial stones, most metals, glass, wood and to thermosetting resins such as polyester, phenolic and epoxy. PC-3™ is available in pint units (2.5 lbs.) or quart units (5.0 lbs.) and is sold in case quantities only. A case of pints contains six units and a case of quarts contains 3 units.
| PC-3™ Coverage Rates | 1/16” (1.59 mm) thick | 1/8” (3.18 mm) thick | 1/4” (6.35 mm) thick | 3/8” (9.53 mm) thick |
| Pint Unit: 2.5 lbs (1.14 kg) | 5.56 ft² (.516 m²) | 400 in² (2581 cm²) | 200 in² (1290 cm²) | 133 in² (860 cm²) |
| Quart Unit: 5 lbs (2.28 kg) | 11.1 ft² (1.03 m²) | 800 in² (5161 cm²) | 400 in² (2581 cm²) | 266 in² (1716 cm²) |
RATE OF COVERAGE EXAMPLE - Assuming a thickness of 1/8 in. (3.18 mm), 1 lb (454 g) of PC-3™ will cover approximately 160.0 in² (1032 cm² ). The following table indicates various coverage rates per size of PC-3™ packaging.
Instructions
Safety - Use in a properly ventilated area (“room size” ventilation). Wear safety glasses, long sleeves and rubber gloves to minimize contamination risk.
Store and use material at room temperature (73°F/23°C). This product has a limited shelf life and should be used as soon as possible.
Any surface to which the PC-3™ will be applied should also be at least 73°F/23°C. Sand surface and wipe clean with fast drying solvent (such as acetone) prior to applying PC-3™. Surface must be clean, dry, and free of all contaminants such as oil, grease, water, dust, etc. Mask adjacent areas with masking tape, then strip tape off as soon as installation is completed. Remove excess or unwanted cement with solvent before it sets.
Because no two applications are quite the same, a small test application to determine suitability for your project is recommended if performance of this material is in question.
Measuring & Mixing - It is important that Parts A & B be mixed accurately in equal amounts. Excess amounts of either Part A or B will cause improper curing of the material. After dispensing equal amounts of Parts A & B, mix thoroughly for 5 minutes, making absolutely sure that you scrape the sides and bottom of the mixing container several times. If you notice streaks in the mixed material, it is not mixed thoroughly enough. Normal cure time is 24 hours.
