1. Pentaerythritol CAS 115-77-5 is mainly used in the coating industry and can be used to manufacture alkyd resin coatings, which can improve the hardness, gloss, and durability of the coating film.
2. Pentaerythritol CAS 115-77-5 is also used as a raw material for rosin esters required in paints, varnishes, and printing inks, and can be used to produce drying oils, flame retardant coatings, and aviation lubricants.
3. Pentaerythritol is also used in the production of pharmaceuticals, pesticides, and other products.
4. Pentaerythritol molecules contain four identical hydroxymethyl groups with high symmetry, making them commonly used as raw materials for the production of multifunctional compounds. Nitrification can produce pentaerythritol tetranitrate, which is a high explosive; Esterification can yield pentaerythritol triacrylate, which can be used as a coating.
5. Pentaerythritol can also be used as a flame retardant for adhesives, and can be combined with ammonium polyphosphate to obtain an expanding flame retardant.
6. Pentaerythritol is also used as a crosslinking agent for polyurethane, providing branched chains within the polyurethane.
Packed in 25 kg per drum or based on customers' requirements.
Store in a cool and ventilated warehouse.
Stay away from sources of fire and heat. It should be stored separately from oxidants, acids, etc., and avoid mixing storage.
Equip with corresponding types and quantities of fire-fighting equipment. The storage area should be equipped with suitable materials to contain leaked materials.
Pentaerythritol Use plastic bags wrapped in polypropylene woven bags or burlap bags for packaging.
When the concentration of pentaerythritol dust in the air exceeds 30g/m3, it can form an explosive mixture with the air, and an explosion occurs when it exceeds 400 ℃.
Therefore, it is advisable to store in a cool, dry, ventilated place, moisture-proof, and fireproof. Store and transport according to general chemical regulations.
In the coatings industry, pentaerythritol is primarily used as a key ingredient in alkyd resin formulations. Here are some specific uses and benefits of pentaerythritol in this regard:
1. Alkyd resin: Pentaerythritol is a common component of alkyd resins, which are widely used in oil-based paints and coatings. These resins have excellent adhesion, durability and gloss.
2. Improved Drying Properties: Pentaerythritol CAS 115-77-5 helps improve the drying properties of alkyd coatings. It helps form a cross-linked network, which enhances the drying process and shortens the curing time.
3. Enhance gloss and finish: Using pentaerythritol in the resin formulation can improve the gloss and overall finish of the paint, making it more aesthetically pleasing.
4. Flexibility: Pentaerythritol-based alkyd resins have good flexibility and toughness, which are very important for coatings that need to withstand various environmental conditions.
5. Compatibility with other ingredients: Pentaerythritol CAS 115-77-5 can enhance the compatibility of different ingredients in the coating formulation, resulting in better performance and stability of the final product.
6. Low Volatile Organic Compounds: Some formulations using pentaerythritol can help reduce the VOC content in paints, making them more environmentally friendly.
