Processing Methods & Reference Formulations
A. Solvent-Free Alkyd Resin for Brush Paints
This formulation produces a clear, low-viscosity alkyd resin suitable for paints with low solvent content.
| Key Ingredients | Indicative Dosage (% w/w) |
|---|---|
| Tall Oil Fatty Acid | 61.0% |
| Pentaerythritol | 12.8% |
| Hypophosphorous Acid | 1.1% |
| Trimellitic Anhydride | 25.1% |
B. Synthetic Lubricant Base Stock (Aviation Grade)
This describes the reactants for a polyol ester (POE) base stock used in high-performance lubricants, such as aviation turbo oils. The exact percentages of the fatty acids are adjusted to achieve desired properties like viscosity and low-temperature performance.
| Key Ingredients | Indicative Dosage (% w/w) |
|---|---|
| Technical Pentaerythritol | Polyol (85-92% monopentaerythritol, 8-15% dipentaerythritol) |
| C5-C10 Carboxylic Acids | Acid Reactants (blend of linear and branched acids) |
Dosing Guidelines
A. Dosing by Application
| Application | Recommended / Max Dosage |
|---|---|
| Alkyd Resins for Paints | 7.00% – 16.25% |
| Synthetic Lubricants (Polyol Esters) | Stoichiometrically reacted with fatty acids; technical grade contains 85-92% monopentaerythritol. |
About Pentaerythritol
Pentaerythritol (C₅H₁₂O₄, CAS 115-77-5) is a white crystalline polyol powder with four reactive hydroxyl groups, making it a key building block for alkyd resins and varnishes, synthetic ester lubricants, PVC stabilisers and intumescent coatings (CASE). With high thermal stability, low toxicity and non-hygroscopic handling, it is supplied in technical and high-purity grades. Elchemy supplies pentaerythritol in bulk with full documentation; download the technical data sheet (TDS) for specifications.
Pentaerythritol Grades: Technical, 98% Mono & Dipentaerythritol
Pentaerythritol is specified by mono-content and purity. Technical grade (typically \~88% monopentaerythritol with dipentaerythritol) suits alkyd resins and general coatings. High-purity 98% mono grade is used where consistent reactivity is required, such as synthetic lubricants. Dipentaerythritol (higher-functionality polyol) is used in high-performance coatings and lubricants. Tell us your application and we will supply the correct pentaerythritol grade.

Request a bulk quote for pricing within 48 hours, or request a sample for evaluation. For buyers comparing where to buy pentaerythritol for sale with reliable delivery and documentation, start with a quote and we'll confirm grade, availability and shipping.
- Versatile Polyol: Essential in resin and stabilizer production, enhancing product performance.
- Function: Primarily acts as a polyol building block and cross-linking agent. In cosmetics, it functions as a humectant and skin conditioning agent.
- High Purity Standards: Ensures consistent quality for industrial applications.
- Features: High thermal and chemical stability, four reactive hydroxyl groups, high melting point, non-hygroscopic (does not absorb moisture), and low toxicity.
- Eco-Friendly Production: Focus on sustainable manufacturing practices.
- Benefits: Enhances hardness, gloss, durability, and weather resistance in coatings. Improves thermal stability in lubricants and plastics. Acts as a char-forming agent in intumescent flame retardants.
- Durability Enhancer: Improves the longevity and flexibility of coatings.
- Key Explosive Precursor: Used in the synthesis of PETN for military applications.
