What is UPVC Solvent Cement?
UPVC (Unplasticized Polyvinyl Chloride) solvent cement is a chemical adhesive that creates a permanent molecular bond between PVC pipes and fittings. Unlike mechanical fasteners, solvent cement works by temporarily softening the plastic surfaces, allowing them to fuse together as the solvent evaporates. The 946ml IPS Weld-On formulation is specifically engineered to meet industry standards for strength, viscosity, and application characteristics.
The TMIPS100U946 product code indicates this is a specialized formulation designed for professional-grade applications. The 946ml container size is standard for commercial plumbing and construction projects across India, providing sufficient quantity for multiple installations while remaining cost-effective.
Key Specifications and Properties
Chemical Composition and Strength
IPS Weld-On UPVC 100 solvent cement contains a carefully balanced blend of PVC resin, plasticizers, and volatile organic solvents. This formulation creates bonds that are typically stronger than the pipes themselves when properly applied. The cement achieves approximately 90-95% of the pipe's tensile strength within 24 hours of application, making it suitable for both pressure and non-pressure applications.
The product meets international standards including ASTM D2564 and Indian Standards (IS 8130), ensuring compatibility with pipes manufactured across India and imported materials. This standardization is particularly important for projects in major cities like Mumbai, Delhi, Bangalore, and Hyderabad where building codes are strictly enforced.

Proper Application Techniques
Surface Preparation
The success of any solvent cement joint depends heavily on proper surface preparation. Before applying the 946ml IPS Weld-On cement, ensure:
Clean all surfaces: Remove dust, dirt, and debris from pipe and fitting surfaces using a dry cloth. Any contamination can compromise the bond quality.
Check for moisture: Pipes must be completely dry. In humid conditions common in coastal Indian cities, allow extra drying time.
Inspect for defects: Look for cracks, splits, or manufacturing defects on pipes and fittings before assembly.
Use appropriate primers: For certain applications or when specified by local building codes, use a PVC primer before applying solvent cement.
Application Process
Following these steps ensures optimal results when using the 946ml IPS Weld-On cement:
Apply cement to the fitting: Using the brush applicator, apply a generous coat of solvent cement to the inside surface of the fitting socket. The cement should cover the entire contact area.
Apply cement to the pipe: Apply a slightly lighter coat to the outside of the pipe end. The fitting receives the heavier coat because it has a larger surface area.
Assemble quickly: Push the pipe into the fitting with a slight twisting motion. This ensures even distribution of the cement and removes air pockets.
Hold firmly: Maintain pressure on the joint for 30 seconds to ensure proper contact between surfaces.
Wipe excess: Remove any excess cement with a clean cloth immediately after assembly.
Environmental Considerations
Temperature and humidity significantly affect solvent cement performance. In India's varied climate conditions:
Optimal temperature range: 15-30°C provides ideal working conditions. In hotter regions like Delhi or Jaipur, work during cooler parts of the day.
Humidity effects: High humidity in coastal cities like Mumbai or Kochi may extend drying times. Ensure adequate ventilation.
Cold weather: In cooler regions or during winter months, allow extended curing time before pressurizing systems.
