1. Product Introduction & Main Application
Arnico’s Formalin is a clear, colorless solution of formaldehyde gas in water at a 37% concentration, supplied with methanol as a stabilizer. This highly reactive chemical substance is one of the most basic industrial intermediates in the world, serving as the primary raw material for the production of various engineering resins (Urea-Formaldehyde, Phenol-Formaldehyde, and Melamine-Formaldehyde) as industrial wood adhesives, and as a powerful disinfectant and preservative.

3. Features & Benefits
-
Excellent Storage Stability: The presence of methanol prevents the spontaneous polymerization of formaldehyde into solid paraformaldehyde.
-
Fast & Complete Reactivity: The highly active carbonyl group reacts with urea, phenol, and melamine, producing high-strength thermosetting resins.
-
High Purity & Iron Control: Prevents discoloration of the final resin, which is vital for clear adhesives and high-value products.
-
Powerful Disinfectant Action: Denatures microbial proteins and preserves biological specimens.
4. Industrial Applications
-
Wood & Furniture Industry: The raw material for Urea-Formaldehyde (UF) and Phenol-Formaldehyde (PF) resins for MDF, particleboard, and plywood.
-
Chemical Industry: The production of pentaerythritol, hexamine, and MDI.
-
Medical & Veterinary: A disinfectant and a tissue fixative.
-
Automotive & Textile Industry: Coating resins and anti-wrinkle fabric treatments.
5. Safety & Handling
-
MSDS (Material Safety Data Sheet): This solution is toxic, corrosive, and a severe irritant. Its vapors are carcinogenic and cause respiratory sensitization. The Arnico MSDS is mandatory.
-
Storage Conditions: Store in 304 stainless steel or polyethylene tanks, at a temperature of 20-30°C (to prevent paraformaldehyde precipitation in cold), and away from oxidizers and alkalis.
-
Personal Protective Equipment (PPE): A full-face respirator with a specific formaldehyde canister, acid-resistant clothing, neoprene gloves, and chemical goggles are required.
6. Quality Assurance & COA
Arnico Formalin shipments are accompanied by a Certificate of Analysis (COA) detailing the formaldehyde concentration, methanol content, and acidity.
