Market Background

The European construction and renovation market places strong emphasis on environmental compliance, indoor air quality, and installation efficiency. Flooring adhesives used in residential, commercial, and public buildings are subject to increasingly strict regulations related to VOC emissions and workplace safety. In addition, Europe’s mature flooring market demands products that combine reliable bonding performance with simplified application processes, especially for renovation and fast-track installation projects.

As sustainability standards continue to evolve, flooring adhesive manufacturers are under pressure to reduce formulation complexity while maintaining compliance with environmental certifications and installer expectations.

Customer & Application Scenario

The customer is a European flooring adhesive manufacturer supplying products for wood flooring, vinyl flooring, and elastic floor coverings in residential and light commercial applications. Typical installation scenarios include renovation projects and interior finishing, where ease of application, low odor, and fast return to service are critical.

Key customer requirements included:

• Compliance with low-VOC and indoor air quality standards
• Elimination of catalyst-based curing systems to simplify formulation and handling
• Smooth application and easy troweling for installers
• Reliable adhesion to common flooring substrates

The customer specifically sought a solution that could reduce formulation complexity while maintaining stable performance across different flooring types.

Our Solution 

To address these requirements, the customer developed a flooring adhesive based on Risun’s NB STP Series, designed for catalyst-free curing and environmentally compliant formulations. The High reactivity STP-based approach allowed the adhesive to cure through ambient moisture without the need for additional catalysts, simplifying both formulation and production.

Key technical characteristics of the solution include:

• Polymer technology: High reactivity STP (Silane-Terminated Polyether) polymer
• Curing system: Catalyst-free, moisture-curing mechanism
• VOC profile: Low VOC, suitable for European indoor air quality requirements
• Application behavior: Easy troweling, good wetting, and stable open time
• Processing advantages: Reduced formulation complexity and improved production stability

By utilizing Risun’s product, the customer achieved a balanced combination of adhesion performance, environmental compliance, and installer-friendly application behavior. The catalyst-free system also improved formulation robustness and reduced sensitivity during manufacturing.

Customer Feedback

Following market introduction, the customer reported positive feedback from both installers and distributors. Applicators highlighted the low odor and smooth application, particularly in occupied indoor environments. The simplified curing system reduced handling concerns and improved consistency during installation. From a manufacturing perspective, the customer noted improved formulation stability and easier quality control compared with catalyst-dependent systems.

Overall, the product was well received as a practical solution that aligned with European regulatory expectations without increasing installation complexity.

Summary

This case demonstrates how STP-based, catalyst-free flooring adhesive systems can effectively address the combined demands of environmental compliance, application efficiency, and reliable performance in the European market. By adopting Risun’s high reactivity STP resin technology, the customer successfully developed a low-VOC flooring adhesive that meets regulatory requirements while delivering ease of use and consistent bonding performance. Such solutions provide a sustainable and application-oriented pathway for flooring adhesive manufacturers serving compliance-driven markets.
