32 Adhesives, Solvents, Resins
Glues and thinners are all stored tightly closed in the flammable cabinet. All containers should be returned with the surfaces cleaned after use. If you are using the glue and the container is empty, please fill the container or ask the instructor for assistance.
Follow these instructions when working with hazardous materials, e.g., glues, solvents, resins.
- Place a protective surface under your work. This protective surface can be paper or a reusable plastic sheet.
- Don protective gloves, eyewear, and your personal respirator.
- Glues and thinners should be kept away from heat or flames.
- Turn on the ventilation system prior to use after closing all windows. Place the snorkel 6” from the glue. In order to be the most effective, the nozzle must be no more than 6” from the source of the fumes.
Precautions In case of:
| Skin Contact | Wash with soap and water |
| Eye contact | Flush with large amounts of water with the eye wash apparatus for at least 15 minutes (prior to using the eye wash, let the water run for a few seconds), seek medical attention. |
| Vapor inhalation | Get to fresh air, restore breathing, seek medical attention. |
| Spill | Contain the spill. |
Using Contact Cements: Barge cement and Polyadhesive
Contact cement is a synthetic rubber adhesive that is applied to two corresponding surfaces and allowed to dry before joining to create an instant, permanent bond. Unlike other adhesives, contact cement must dry completely before workpieces are brought together.
- Select the adhesive based on the “strength” of the desired bond and coloration
- Reasons for failed bonds may include coating too think, bonding too soon, and/or not enough pressure.
- Clean the surface
- “Surface energy is a physical property of the surface of a material that determines whether an adhesive will make intimate contact. On a material with high surface energy, a liquid will wet out or spread out on the surface; on a material with low surface energy, the liquid will resist flowing and bead up. An adhesive must wet out the substrate to provide a bond.” (https://www.3m.com/3M/en_US/bonding-and-assembly-us/applications/material-bonding/).
- Rough the surface moderately
- A rough surface for bonding often leads to stronger bonds because there is more surface area on material and more mechanical interlocking.
- For the most successful application, the glue should be of medium consistency to be applied with a consistent layer. If necessary, the barge cement can be thinned using addition of barge thinner to the cement. Mix with a disposable tongue blade found in the flammable cabinet.
- Apply to the glue to the two mating surfaces.
- Allowed to dry and get tacky (~5 min). Apply a second coat if you want a stronger bond.
- Position the pieces correctly and press the pieces together for a solid bond. Avoid pockets of air.
- After use, secure the cap on the container tightly. If the cap is not secured, air will enter the container allowing the thinners to evaporate and the glue to harden rendering it useless.
PLUSERIES 60 Second Curative
- Store in a fire cabinet, in the room, in original packaging, with the lid tightly secured, when not in use.
- Avoid contact with eyes and skin. Avoid breathing dust/fume/gas/mist/vapors/spray. Do not swallow. Handle
open containers with care. When using, do not eat, drink or smoke. Use only in a well-ventilated area
Preparation (see video below):
Remove the cap of the adhesive cartridge by twisting and pulling off for the 50ml size. On the 215ml cartridge pry the uppermost slot with a flat driver.- Properly place the cartridge into the gun. Prior to attaching the mixing tip, dispense a small amount of adhesive to ensure both sides flow evenly. If the both sides do not flow evenly, using a small poker carefully enlarge the restricted side to ensure full flow.
- Attach mixing tips by locking tabs on the 50ml size or screwing on for the 215ml
- Ensure all surfaces to be bonded are clean and free from dust oils waxes. When possible roughen surfaces for increased adhesion
- Apply a generous amount of +PLUSeries adhesive
- Release the pressure on the metal tab located on the back of the applicator gun. This will allow you to easily remove the tip for your next use.
- Leave tip on the cartridge to act as a cap.
- Assemble with the mating part within the recommended working time.
- Allow adhesive to cure per recommendation.
- Sand and buff using industry standard tools.
- Special Note: In any application involving weight bearing we recommend a minimum cure time of 15-minutes and additional reinforcement such as fiberglass cast wrap.
Recommended Applications:
- Plastics: Acrylics, Styrenics, Vinyl Esters, Urethanes, PETG, Epoxy, Polyesters
- Composite Fibers, Fiberglass
- Metals: Aluminum, Carbon, Steel
- Wood, CAD Foams, Dry Plaster
Non-recommended Applications: Polypropylene, Polyethylene, Copolyesters
Clean Up:
- Use a solvent such as acetone before the adhesive cures.
- For cured adhesive carefully scrape it off.
- Large spills of un-cured material should be cleaned up with an absorbent material and disposed of following your local policies for chemical disposal.
