MCLUBE-1720L (1-USgl-Ctnr)

Additional Product Information

Overview

:contentReference[oaicite:0]{index=0} 1720L is a semi-permanent mold release agent and dry-film lubricant designed for high-efficiency industrial molding and surface processing. It is widely used in manufacturing and maintenance environments where clean, repeatable release performance is required for natural and synthetic rubber, plastic, and composite materials. Aviation MRO and industrial production teams rely on this PTFE-based coating technology to reduce tooling friction, minimize scrap, and support multiple release cycles per application.

• Anti-stick coating for composite or elastomer handling processes
• Support lubricant for precision mechanical fitting operations

Compatibility & Safety Notes

• Compatible with natural rubber, synthetic elastomers, thermoplastics, urethane systems, and composite molding substrates
• Application surface must be clean, dry, and free from previous release agents, rust, or process contaminants
• Product is flammable due to solvent content; keep away from open flames, sparks, and ignition sources
• Use in well-ventilated areas and follow protective equipment guidelines
• Active ingredients are considered essentially low-toxicity under normal use
• Avoid exposure to temperatures exceeding 550°F (288°C) to prevent hazardous decomposition byproducts

Packaging & Procurement

• Available Packaging: 1-gallon, 5-gallon, and 55-gallon containers
• Storage: Store in sealed containers away from heat, flame, and direct sunlight
• Ease of Use: Can be applied by spray gun, brushing, wiping, dipping, or atomizing systems
• Process Maintenance: Product may settle during storage; mix before use and periodically during operation

Why McLube 1720L is Chosen for AOG / MRO

• Supports rapid application with instant drying performance
• Enables multiple release cycles per coating, reducing downtime
• Produces low-transfer, clean, non-oily film layers
• Helps maintain part dimensional accuracy and surface quality
• Reduces tooling buildup and maintenance frequency

Practical Suggestions for Your Team (AOG Mindset)

• Condition new molds by applying two initial coatings, allowing the first layer to dry before the second
• For mature tooling surfaces, one thin coating is typically sufficient
• Agitate or mix material if stored longer than one month
• Keep emergency stock inventory in AOG kits for fast deployment
• Train operators on thin-film application techniques to maximize release cycles
