Frequently Asked Questions (FAQs) – Solvent Cement by plastochem

 

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

Solvent cement is a chemical adhesive used to bond plastic pipes and fittings. It works by softening (dissolving) the pipe and fitting surfaces, allowing them to fuse together. As the solvents evaporate, a strong, permanent joint is formed.

2. What types of pipes can be joined using solvent cement?

Solvent cement is suitable for joining PVC, CPVC, and ABS pipes used in plumbing, irrigation, and industrial applications.

3. How do I ensure a proper fit before applying solvent cement?

A proper "interference fit" is required for solvent cement to work effectively. The pipe should fit snugly into the fitting, with 1/3 to 2/3 dry fit before cement application. Avoid loose fits to prevent leaks.

4. How should I prepare the pipe and fitting before applying solvent cement?

To ensure a secure bond:

• Cut the pipe square and remove any burrs.
• Clean the surfaces to remove dirt, oil, or moisture.
• Use Platochem 901 Cleaner for non-pressure systems and ABS pipes.

5. Do I need to apply primer before pvc solvent cement?

Yes, primer must be applied to PVC and CPVC pipes and fittings. It helps soften the surfaces for better adhesion and a stronger bond.

6. How do I apply solvent cement correctly? 

Follow these steps:

1. Apply a heavy coat of cement to the pipe.
2. Apply a light coat to the fitting socket.
3. Apply another coat to the pipe.
4. Insert the pipe into the fitting using a slight twisting motion until it bottoms out.
5. Hold in place for a few seconds to prevent push-out.

7. How do I know if I’ve applied enough cement?

If applied correctly, a small bead of cement should appear at the pipe/fitting interface. Wipe off excess cement to speed up curing.

8. How long does solvent cement take to cure?

• 24 hours is the recommended curing time before pressure testing.
• Curing may take longer in cold weather or humid conditions.

9. Can I use gelled upvc solvent cement?

No, always check that the solvent cement is free-flowing. Gelled cement should be discarded, as it won’t create a reliable bond.

10. What should I do if the pipe does not grab or fuse properly?

If the pipe and fitting do not grab shortly after joining, the joint may not be secure. Avoid using it, as it could leak or pull apart.

11. Is cpvc solvent cement safe to use?

Yes, but use it in a well-ventilated area and avoid direct inhalation. Always follow safety precautions, including wearing gloves and eye protection.

12. Can solvent cement be used in wet conditions?

No, the pipe and fitting should be completely dry before applying solvent cement for the best results.
