Melamine
Applications
Used in melamine-formaldehyde resins for laminates, coatings, adhesives, and molded plastics. In paper and textile finishing, it imparts hardness, gloss, and resistance to chemicals. It also functions as a flame retardant additive in polymers.
Safety & Risks
Toxic if ingested; avoid dust inhalation and use in food-contact materials only under regulatory compliance.
Packaging
Delivered in 25 kg woven polypropylene bags or 1,000 kg bulk sacks. Store in a cool, dry, well-ventilated area.
