FAQs About Solvent Cement

1. What is solvent cement and how does it work?

Solvent cement is an adhesive used to join PVC, UPVC, and CPVC pipes and fittings. It works by softening the surfaces of the pipes, allowing them to fuse together as the solvent evaporates, creating a strong and leak-proof bond.

2. What is the composition of PVC solvent cement?

PVC solvent cement is typically a mixture of PVC resin and solvents like tetrahydrofuran (THF) or cyclohexanone. These solvents dissolve the surface of the PVC, enabling the pipes and fittings to bond when assembled.

3. How long does it take for PVC solvent cement to bond?

PVC solvent cement offers fast bonding, achieving initial strength within minutes. However, full curing may take several hours, depending on temperature and humidity.

4. What is the pressure rating of a bonded PVC joint?

Properly bonded PVC joints maintain the pressure rating of the pipes and fittings, ensuring a strong and watertight connection.

5. In what colors is PVC solvent cement available?

PVC solvent cement is available in clear, gray, and other colors. The color does not affect performance but helps match the cement to the PVC pipes for aesthetic purposes.

6. What are the safety precautions when using solvent cement?

When working with solvent cement:

• Use in a well-ventilated area to avoid inhaling fumes.
• Wear protective gloves and goggles to prevent skin and eye irritation.
• Avoid open flames as some solvent cements are flammable.

7. What are the correct steps for applying UPVC solvent cement?

1. Cut the pipe squarely to the desired length and remove any burrs.
2. Clean and dry the joining surfaces using a dry cloth.
3. Apply solvent cement on the outer pipe surface and the socket depth using the provided brush.
4. Assemble the joint quickly while the cement is still wet. Rotate the pipe slightly for better adhesion and hold for 60–90 seconds to prevent push-out.
5. Allow at least 15 minutes before handling the pipe.

8. Can solvent cement be used for high-pressure applications?

Yes, UPVC solvent cement is suitable for high-pressure drainage systems. It provides high bond strength, leak-proof sealing, and resistance to chemicals and pressure.

9. Is primer necessary before applying solvent cement?

Using a primer is recommended, especially for large-diameter pipes and high-pressure applications. It helps prepare the surface for better bonding and ensures a stronger joint.

10. What are the main applications of cPVC solvent cement?

PVC solvent cement is widely used in:

• Agriculture piping systems
• Household plumbing
• Sewage and drainage systems
• Telephone conduit pipes

11. What packaging sizes are available for solvent cement?

Solvent cement is available in various sizes, including:

• Small PET bottles: 25ml, 50ml, 100ml, 250ml, 500ml, 1L
• Bulk packaging: 5L Jerry Cans, 30L Carboys, 200L Barrels

12. What is the warranty for solvent cement?

Since storage and application conditions vary, manufacturers guarantee uniform quality but do not assume responsibility for improper storage or use.
