PTN3500 Polypropylene

Updated: 2026-07-31

Overview

PTN3500 is a high-performance industrial adhesive designed for applications requiring strong, durable bonds. It is widely used in sectors such as construction, automotive, and electronics due to its exceptional resistance to heat, chemicals, and mechanical stress. The adhesive is known for its fast curing time and versatility, making it a preferred choice for manufacturers and builders. The formulation of PTN3500 ensures compatibility with a variety of substrates, including metals, plastics, and composites. Its reliability under extreme conditions has made it a staple in industries where failure is not an option. Proper application techniques are crucial to achieving optimal performance.

Physical and Chemical Properties

PTN3500 exhibits a viscous consistency, typically appearing as a clear or light yellow liquid. Its density is approximately 1.1 g/cm³, and it is insoluble in water but soluble in common organic solvents. The adhesive cures rapidly when exposed to air, forming a strong, resilient bond. Key chemical properties include high thermal stability, resistance to solvents, and minimal shrinkage during curing. These characteristics make PTN3500 suitable for environments with fluctuating temperatures and exposure to harsh chemicals. Its performance is consistent across a wide range of industrial applications.

Proper handling of PTN3500 is essential to ensure safety. The adhesive should be used in well-ventilated areas to avoid inhalation of fumes. Protective gloves and goggles are recommended to prevent skin and eye contact. In case of accidental exposure, rinse immediately with water and seek medical attention if necessary. Storage conditions are critical to maintaining the adhesive's efficacy. PTN3500 should be kept in a cool, dry place, away from direct sunlight and heat sources. Containers must be tightly sealed to prevent moisture ingress and premature curing. Shelf life is typically 12 months when stored correctly.

B2B Procurement Guide

When procuring PTN3500, it is important to source from reputable suppliers with verified certifications. Bulk purchases often provide cost savings, but buyers should ensure consistency in quality across batches. Technical specifications, such as viscosity and curing time, should be confirmed to meet project requirements. Request samples for testing before committing to large orders. Evaluate the adhesive's performance under specific conditions relevant to your application. Establish a reliable supply chain to avoid disruptions in production. Pricing varies based on quantity and supplier, with typical ranges between $20 and $50 per kilogram.
