Polyurethane M2688

Updated: 2026-07-19

Overview

M2688 is a high-performance industrial adhesive designed for demanding B2B applications. It is widely recognized for its exceptional bonding strength and versatility across various materials, including metals, plastics, and composites. The adhesive is particularly favored in industries where durability and resistance to environmental factors are critical. Its formulation ensures fast curing times, making it ideal for high-volume production lines. M2688 is also known for its resistance to moisture, chemicals, and temperature fluctuations, which enhances its suitability for harsh operating conditions.

Physical and Chemical Properties

M2688 exhibits a viscous liquid form with a density of approximately 1.1 g/cm³. It is insoluble in water, which contributes to its moisture-resistant properties. The adhesive cures rapidly upon application, forming a strong, durable bond that can withstand significant mechanical stress. Key chemical properties include its resistance to a wide range of solvents and industrial chemicals. This makes M2688 suitable for applications where exposure to corrosive substances is common. The adhesive's thermal stability allows it to perform reliably in temperatures ranging from -40°C to 120°C.

B2B Procurement Guide

Procuring M2688 requires careful consideration of supplier reliability and product consistency. Buyers should verify that suppliers hold relevant certifications, such as ISO 9001, to ensure quality standards are met. Batch testing is recommended to confirm adhesive performance before large-scale purchases. Price negotiations should account for volume discounts, with reference prices typically ranging from $20 to $50 per kilogram. Buyers are advised to request samples for testing and evaluate lead times to align with production schedules. Long-term contracts may offer cost savings and supply stability.
