Description
This 50ml cartridge contains Chem-Set 605 in natural, a toughened two-part methacrylate for structural bonding of engineered plastics, metals, and composites. It dispenses through a static mixer, so both parts are metered and mixed as they leave the nozzle with no cups, sticks, or hand mixing. Working time is 3 to 6 minutes and the bond reaches 1,000 psi in 13 to 16 minutes at 74°F. GREENGUARD Gold certified with VOC content under 10 g/L, which matters on schools, healthcare, and other projects with indoor air quality requirements. Requires a 50ml manual dispense gun and static mixers, both sold separately.

Substrates
- PVC, ABS, PPO, and polycarbonate
- Fiberglass, FRP, and gel coats
- Polyesters including DCPD modified, and vinyl esters
- Styrenics and acrylics
- Urethanes
- Aluminum, carbon steel, and stainless steel, primer suggested
Typical Lap Shear by Substrate
| Substrate | Lap Shear | Failure Mode |
|---|---|---|
| Stainless Steel | 3,343 psi | Cohesive |
| Aluminum | 3,155 psi | Adhesive |
| PVC | 1,391 psi | Substrate |
| PC/ABS | 1,169 psi | Substrate |
| Gel Coat | 578 psi | Substrate |
Substrate failure means the material broke before the bond did. A metal cleaner conditioner is recommended on aluminum and stainless.
Cure Profile by Temperature

|---|---|---|---|
| Working Time | 3 to 6 min | 3 to 6 min | 3 to 3.5 min |
| 500 psi | 15 to 17 min | 11 to 13 min | 8 to 10 min |
| 1,000 psi | 19 to 22 min | 13 to 16 min | 13 min |
Dispensing This Package
Load the cartridge into the gun and remove the end caps. Attach the static mixer and expel a mixer’s length of adhesive before applying. Mate the parts within the working time, then leave them undisturbed until fixture time is reached.
Surface Preparation
Plastics and coated metals usually need only a wipe with a dry rag or light solvent. Raw metal is the same, though results vary with oxidation and scaling. Composites can often be bonded as-is, or lightly abraded to remove mold release. Test your own materials to confirm.
Working Notes
- Static mixing removes hand-mix variability, which matters when bond strength has to be consistent across multiple points.
- Cure rate is temperature sensitive. A cold shop nearly doubles the time to 1,000 psi compared to a warm one.
- Bond line thickness of 0.015 to 0.030 in gives optimum adhesion. Thicker is not stronger.
- Cap the cartridge between uses and change the mixer. Material cures inside a used mixer.
- Non-sagging gel holds position on vertical and overhead bond lines.
- Do not dispense large masses at once. Peak exotherm runs near 320°F on a 10 g mass.
- Clean up before the adhesive cures. Soap and water, citrus terpene, or NMP-based cleaners all work.
- Bulk dispensing equipment should be stainless steel. Avoid brass, copper, and copper-containing alloys.
Common Applications
- Structural bonding of PVC, ABS, and polycarbonate in fabrication and assembly
- Bonding aluminum and stainless steel to plastics and composites
- Fiberglass, FRP, and composite panel bonding
- Gel coat and marine component bonding
- Sign and display fabrication on acrylic and styrenic sheet
- Transportation and specialty vehicle assembly bonding
- Glue-on sink anchor mounting on solid surface, quartz, and engineered stone
- Projects with indoor air quality or low-VOC requirements
- Replacing welds, rivets, and mechanical fasteners on load-bearing joints
Common Questions
What equipment do I need for the 50ml cartridge?
A 50ml manual dispense gun and 1:1 static mixers, both sold separately. The cartridge does not hand mix.
What does Chem-Set 605 bond?
PVC, ABS, PPO, polycarbonate, fiberglass, FRP, gel coats, polyesters, vinyl esters, styrenics, acrylics, urethanes, and metals including aluminum and stainless steel. It also bonds dissimilar combinations such as metal to plastic.
How strong is the bond?
Lap shear cohesive strength is 3,000 to 3,800 psi. On PVC, PC/ABS, and gel coat the substrate typically fails before the bond does.
Is it low-VOC?
Yes. VOC during cure is under 10 g/L and it is GREENGUARD Gold certified under UL 2818.
How does temperature affect cure?
Significantly. At 60°F the bond takes 19 to 22 minutes to reach 1,000 psi versus 13 minutes at 90°F. Apply between 65°F and 85°F.
