Pentaerythritol
White crystalline neopentyl polyol with four primary hydroxyl groups for high-grade alkyd resins, intumescent fireproofing, synthetic esters, and coatings.
Product Overview: High-Purity Pentaerythritol
Pentaerythritol [C(CH2OH)4] is a versatile, polyhydric alcohol containing four primary hydroxyl groups. It appears as an odorless, white crystalline powder and is a fundamental building block in modern organic synthesis.
Sakthima supplies premium technical grade and mono-grade pentaerythritol (purity ≥ 95–98%) with high hydroxyl values, low ash, and minimal moisture. It serves as an essential raw material for alkyd resins, synthetic aviation lubricants, radiation-cure acrylates, rosin esters, and intumescent fire-retardant coatings.
Key Benefits
Superior Alkyd Resin Performance
Provides fast drying times, high crosslink density, gloss retention, and weatherability in alkyd enamel paints.
Intumescent Fire Protection
Acts as the primary carbonific agent in fire-retardant coatings, swelling into an insulating carbon foam during fire exposure.
High-Performance Synthetic Lubricants
Reacts with fatty acids to produce polyol esters for jet engine oils, biodegradable hydraulics, and refrigeration fluids.
Polymer Crosslinking Agent
Enhances flexural modulus, chemical resistance, and hardness in polyurethane and radiation-cure acrylic formulations.
Low Color Index
Ultra-low Gardner color index (≤ 1) prevents yellowing in high-clarity varnishes and specialty finishes.
Applications
Alkyd & Polyester Resins
Intumescent Fire-Retardant Coatings
Synthetic Aviation & Refrigerator Oils
Rosin Esters & Adhesives
