1. Product Introduction & Main Application
Arnico’s Pentaerythritol is a white, crystalline polyol with four reactive hydroxyl groups, produced from the reaction of formaldehyde with acetaldehyde in an alkaline medium. Due to its unique, multi-functional structure, this substance is the primary raw material for producing high-quality alkyd resins for baking enamels and automotive paints, synthetic lubricants for jet engines, and the powerful explosive PETN.

3. Features & Benefits
-
Four Reactive Hydroxyl Groups: Creates a very dense and resistant polymer network in alkyd resins, dramatically increasing coating hardness, gloss, and chemical resistance.
-
Exceptional Thermal & Oxidation Stability (Mono-PE): Suitable for producing polyol ester (POE) base stocks used as high-temperature synthetic lubricants for jet turbines.
-
Exceptional Purity (Nitration Grade): Free from di-pentaerythritol and organic impurities, which is critical for the safe and controlled production of PETN with standard explosive sensitivity and power.
-
Water-Borne Reactivity: Combines well with long-chain fatty acids to produce fast-drying resins.
4. Industrial Applications
-
Paint & Coatings Industry: High-solids alkyd resins for automotive and appliance paints.
-
Lubricant Industry: Ester base stocks for jet engine and compressor oils.
-
Military & Mining Industry: The raw material for PETN in detonators and detonating cord.
-
PVC Stabilizers: An additive that prevents thermal degradation in rigid PVC.
5. Safety & Handling
-
MSDS (Material Safety Data Sheet): This material’s dust is a mild eye and respiratory tract irritant. It is non-flammable. The Arnico MSDS file is available.
-
Storage Conditions: Store in multi-layer bags in a dry, cool, and well-ventilated place, away from strong oxidizers and acids (for nitration consumption).
-
Personal Protective Equipment (PPE): When decanting, the use of a P2 dust mask and safety goggles is recommended.
6. Quality Assurance & COA
Arnico Pentaerythritol shipments are accompanied by a Certificate of Analysis (COA) detailing the purity percentage, melting point, and di-pentaerythritol content.
