INTRODUCTION & OVERVIEW
SETAMINE US-138 is a highly methylated melamine-formaldehyde resin, designed as a crosslinking agent for hydroxy-functional polymers (e.g., alkyds, polyesters, acrylics).
It reacts with the polymer's OH groups during the curing (stoving) process, forming a dense, three-dimensional network.
This results in coatings with exceptional hardness, chemical resistance, durability, and gloss.
KEY PROPERTIES & SPECIFICATIONS
Solids Content: ~98%
Solvent: Isobutanol
Viscosity: Medium to high (specific cP range depends on batch/temp)
Compatibility: Excellent with a wide range of solvent-borne polymers.
Reactivity: Requires acidic catalysts (e.g., p-TSA) for low-temperature cure; cures at elevated temperatures (typically 120°C - 150°C).
FUNCTIONS & APPLICATIONS
Primary Function: Provides crosslinking for thermoset industrial coatings.
Key Benefits:
Excellent Finish Properties: High gloss, mar resistance, and hardness.
Superior Durability: Outstanding resistance to chemicals, solvents, and stains.
Good Flexibility: Contributes to the film's flexibility and adhesion.
Storage Stability: Offers good pot life and compatibility in formulations.
Typical Applications:
Automotive OEM and refinish coatings.
Coil coatings for pre-painted metal.
General industrial metal finishes (appliances, furniture).
High-performance protective coatings.
HANDLING & SAFETY (MSDS SUMMARY)
Hazards: Flammable liquid. May cause skin and eye irritation. Contains formaldehyde (low free formaldehyde).
Storage: Store in a cool, well-ventilated place away from heat and ignition sources. Keep container tightly sealed.
Handling: Use with local exhaust ventilation. Wear chemical-resistant gloves, safety goggles, and protective clothing.
First Aid: For eye contact, rinse cautiously with water for several minutes. Remove contact lenses if present. Seek medical attention. For skin contact, wash thoroughly with soap and water.
PACKAGING
Typically supplied in 200 kg steel drums or 1,000 kg IBCs.
