Market Background

In Southeast Asia, high humidity levels can affect the performance of sealants during application and curing, even in indoor construction environments. While exposure conditions are less severe than outdoor applications, uncontrolled humidity can still lead to variability in curing behavior and final performance.

Customer & Application

The customer is a contractor working on indoor construction projects, including joint sealing for partition systems and interior assemblies. They experienced inconsistent curing and variation in sealant performance across different job sites.

Our Solution

RISUN focused on improving curing stability under high humidity conditions typically found in indoor environments. The SMP system was adjusted to provide more predictable curing behavior and stable application performance.

Attention was also given to application practices, including joint preparation and environmental control during installation.

Key Technical Considerations

• Controlled curing under high humidity conditions
• Stable application behavior in indoor environments
• Consistent joint performance across sites
• Reduced sensitivity to environmental variation

Results

After implementation, curing behavior became more predictable, and application consistency improved across different indoor project sites.

Customer Feedback

The customer reported fewer issues related to uneven curing and improved confidence in material performance during installation.

Summary

Even in indoor construction, humidity can influence sealant performance. Controlling curing behavior is key to achieving consistent results.
