CHEMGLAZE M201 Part-B Tan Anti-Erosion Coating – Gallon Can for MRO Operations
CHEMGLAZE M201 Part-B is the isocyanate hardener component of the CHEMGLAZE M201 anti-erosion polyurethane system, available in the gallon can format — the standard MRO-scale supply for maintenance facilities performing regular anti-erosion coating and re-coating of rotor blades, propellers, and leading edge structures. The gallon Part-B hardener is matched with Part-A base at the specified ratio to produce the mixed CHEMGLAZE M201 anti-erosion coating ready for spray application.
CHEMGLAZE M201 in the tan color is the standard anti-erosion coating used on commercial helicopter rotor blades, fixed-wing propellers, and civil aviation leading edges where the natural tan/amber color of the aliphatic polyurethane anti-erosion system is specified or acceptable. The gallon format of Part-B provides the standard maintenance quantity for MRO shops processing a moderate number of rotor assemblies per maintenance cycle.
Maintaining stock of both Part-A and Part-B in the gallon format enables MRO facilities to mix appropriate batch sizes for the coating operation without the material handling and storage requirements of the larger 5 gallon pail, while providing sufficient material for multiple component coating operations between reorder cycles.

Technical Information
CHEMGLAZE M201 Part-B contains the aliphatic polyisocyanate component that cures the polyol base of Part-A to form the crosslinked polyurethane anti-erosion film. The isocyanate must be kept dry at all times — moisture contact causes the isocyanate groups to react with water rather than with the polyol, forming carbon dioxide gas bubbles that create a foamy, porous coating film with dramatically reduced erosion resistance and adhesion. Always keep Part-B containers tightly sealed when not in use and never dilute with water.
The gallon container should be stored upright in a sealed condition with a moisture-excluding atmosphere above the product surface — use dry nitrogen blanket on partially emptied cans in humid climates to prevent moisture-induced degradation of the isocyanate component. Check the isocyanate for the characteristic clear, light amber appearance before use — cloudy, thickened, or gelled material indicates moisture contamination and the can should be rejected.
Mix Part-B with Part-A at the specified ratio, ensuring thorough incorporation of all components. The mixed pot life is limited — apply within the pot life specified in the CHEMGLAZE M201 ADS for the application temperature. Attempting to apply beyond the pot life produces a thickened coating with poor flow, leveling, and adhesion properties.

Frequently Asked Questions
Q: What is CHEMGLAZE M201 Part-B gallon?
A: Part-B gallon is the gallon-format isocyanate hardener for CHEMGLAZE M201 tan anti-erosion polyurethane — mixed with Part-A at the specified ratio for spray application on rotor blades and leading edges.
Q: MPN for CHEMGLAZE M201 Part-B gallon?
A: MPN is 3001690.
Q: Why must Part-B be kept dry?
A: The isocyanate in Part-B reacts with moisture, forming CO2 gas bubbles in the coating film — producing a foamy, porous coating with severely reduced anti-erosion performance. Always keep Part-B sealed and moisture-free.
Q: How do I store CHEMGLAZE M201 Part-B?
A: Store sealed upright. In humid climates, use dry nitrogen blanket on opened cans. Check for clear, light amber appearance before use — cloudy or gelled material indicates moisture contamination.
Q: Can Part-B be used with any Part-A?
A: No. CHEMGLAZE M201 Part-B is formulated for use only with CHEMGLAZE M201 Part-A. Mixing with other Part-A products produces unknown chemical ratios and unqualified coating performance.
