LOCTITE® 4031

LOCTITE® 4031 is a high-performance, medical grade instant adhesive engineered specifically for applications where vapor control is difficult or critical. This low-odor, low-blooming cyanoacrylate adhesive delivers uniform stress distribution and exceptionally high tensile and shear strength, making it an essential component for demanding production lines. Its unique formulation minimizes cosmetic whitening on surrounding areas while maintaining an efficient manufacturing workflow.

LOCTITE 4031 is thoroughly tested to Henkel's strict protocols based on ISO 10993 biocompatibility standards, ensuring complete compliance for the assembly of disposable medical devices. Whether your production facility requires the 20g bottle (IDH 229804) for manual workstations or the 1lb container (IDH 229805) for automated dispensing systems, we maintain bulk inventory in stock to secure your supply chain with competitive wholesale pricing.

Key Performance Benefits & Applications

• Medical Device Certification: Certified to ISO 10993 biocompatibility protocols, streamlining validation cycles for medical equipment and single-use device manufacturing.
• Low-Odor & Low-Blooming: Minimizes the "frosting" effect and reduces volatile emissions, creating a safer operational environment where vapor extraction systems are limited.
• Universal Substrate Bonding: Engineered to provide rapid cross-linking and robust structural adhesion across plastics, metals, and elastomeric materials.
• Production Efficiency: Single-part, fast-curing formulation eliminates mixing requirements and integrates seamlessly with automated [Link to: Precision Metred Dispensing Equipment].

Technical Specifications

• Product Variants / IDH Numbers: 20g Bottle (IDH 229804), 1lb Container (IDH 229805)
• Chemical Type: Alkoxyethyl cyanoacrylate
• Appearance: Clear, transparent, colorless liquid
• Viscosity: Low viscosity, optimized for thin bond gaps up to 0.05 mm
• Curing Type: Atmospheric humidity / Moisture cure
• Primary Application: Component bonding and structural assembly
• Full Strength Development: Rapid initial fixture; ultimate chemical and solvent resistance is achieved after a 24-hour cure cycle
• Optimal Storage Temperature: 8°C to 21°C (Refrigerated storage below 8°C or exposure above 28°C will degrade the product’s physical properties)

Industrial Processing Guidelines

For maximum bond integrity, ensure all mating surfaces are completely clean, dry, and free from manufacturing oils or residual grease prior to adhesive application. LOCTITE 4031 delivers its highest performance across tight-fitting joints up to 0.05 mm. If assembly lines require faster fixture speeds due to low ambient humidity or larger bond gaps, the application of a commercial-grade Loctite 770 can significantly accelerate cure times.

Frequently Asked Questions

Is LOCTITE 4031 compliant for use in medical device manufacturing?
Yes, LOCTITE 4031 has been rigorously tested against Henkel's standard protocols based on ISO 10993 biocompatibility requirements, making it fully certified for the assembly of disposable medical devices.

What are the advantages of using a low-blooming adhesive like LOCTITE 4031?
LOCTITE 4031 is an alkoxyethyl cyanoacrylate that drastically reduces volatile vapors. This suppresses the white "blooming" or frosting effect on adjacent components, ensuring clean, cosmetically critical assemblies without sacrificing structural bond strength.
