Application and Usage:
1. Pentaerythritol is mainly used in the paint industry, and can be used to make alkyd resin paints, which can improve the hardness, gloss and durability of paint films.
2. It is also used as the raw material of rosin resin required for paints, varnishes and printing inks, and can be used to make drying oils, smoldering paints and aviation lubricants. In addition, it is also used in the production of medicines and pesticides. The molecule of pentaerythritol contains four equivalent methylol groups and has a high degree of symmetry, so it is often used as a raw material for the preparation of multifunctional compounds. Pentaerythritol tetranitrate can be obtained by its nitration, which is a high explosive; pentaerythritol triacrylate can be obtained by esterification, which can be used as a coating.
3. It can also be used as a flame retardant for adhesives, and can be combined with ammonium polyphosphate to obtain an intumescent flame retardant. Also used as a crosslinking agent for polyurethanes, providing branching within polyurethanes
