Complete Your Bonding System: Specialty Adhesives & Hardeners
The unseen essentials that guarantee bond strength, durability, and consistency in mass production. We don't just sell adhesives; we perfect the entire bonding process.
Why a Perfect Bond is More Than Just Glue
In footwear manufacturing, 99% success is a failure. A strong bond depends on a complete system where every component works in synergy. Hardeners, primers, and cleaners are not additives; they are essential process chemicals that prepare surfaces, control curing, and enhance performance under real-world factory conditions. Ignoring them leads to delamination, inconsistency, and production losses.
Maximize Strength
Unlock the full potential of your adhesive with complete system integration.
Ensure Consistency
Achieve repeatable results across every batch with systematic approach.
Improve Durability
Enhance heat, water, and chemical resistance for long-lasting performance.
Bond Difficult Materials
Overcome challenges with modern composites and treated leathers.
A System for a Flawless Bond
Engineered Solutions for Every Bonding Challenge
Precision-formulated products designed to deliver uncompromising performance across all industrial adhesive applications
Hardeners: The Key to Bond Performance & Durability
Our Desmodur-type hardeners are precision-formulated to work seamlessly with our polyurethane (PU) and polychloroprene (CR) adhesives. They create powerful cross-linked structures that significantly boost final bond strength, heat resistance, and longevity.
Primary Applications
- High-performance athletic footwear requiring superior durability
- Industrial and safety boots exposed to harsh environments
- Applications requiring long-term water and chemical resistance
Hardeners increase bond strength by up to 300% and extend service life in demanding industrial applications.

Frequently Asked Questions
About Hardeners & Primers - Your Technical Questions Answered
How do I select the right hardener for my adhesive?
+
Selecting the right hardener depends on several critical factors including your specific adhesive formulation, application requirements, and environmental conditions. Our technical team recommends considering:
- Curing speed requirements for your production line
- Temperature and humidity conditions in your facility
- Final bond strength and flexibility requirements
- Substrate materials being bonded
Contact our technical support team for personalized hardener recommendations based on your specific application.
What is the typical mixing ratio for adhesive and hardener?
+
Mixing ratios vary significantly depending on the specific adhesive system and hardener type. However, common ratios include:
⚠️ Important:
Always follow the specific mixing ratio provided on your product technical data sheet. Incorrect ratios can result in poor curing, reduced bond strength, or complete adhesive failure.
When is a primer absolutely necessary?
+
Primers are essential in specific situations to ensure optimal adhesion and long-term bond performance. A primer is absolutely necessary when:
Critical Applications:
- • Bonding to low-energy surfaces (PP, PE)
- • Outdoor or marine environments
- • High-stress applications
- • Safety-critical bonds
Recommended Applications:
- • Synthetic leather bonding
- • Rubber to fabric adhesion
- • Metal substrate preparation
- • Moisture-prone environments
Our technical team can perform adhesion tests to determine if primer is required for your specific substrate combination and application conditions.
What is the shelf life and proper storage for these products?
+
Proper storage is crucial for maintaining product performance and extending shelf life. Here are our standard guidelines:
Temperature
15-25°C (59-77°F)
Avoid freezing
Humidity
Keep containers
tightly sealed
Shelf Life
12-24 months
from manufacture
💡 Pro Tip:
Always check the batch date and rotate stock using FIFO (First In, First Out) principles. Products stored beyond recommended shelf life should be tested before use to verify performance.
