Chemical Description

  • Hydroxypropyl Acrylate (HPA) is a colorless liquid which sometimes can also be white in the color, the chemical formula for HPA is C6H10O3.
  • The boiling point of HPA is standing at 70 degrees Celsius and the flash point is 65 degrees Celsius. Its mass is 130.062 g/mol and the molecular weight is 130.4 g/mol.
  • HPA is soluble in water and is miscible with oxygenated solvents.
  • It forms very strong bonds withy other molecules which results in the strengthening of the molecules and also enhancement in their stability and functionality. Also, it mediates at gathering and smoothening of molecules.
  • HPA mainly creates polymers and shapes them into useful materials and makes them with desirable properties such as flexibility and durability.
  • It can be used in water-based coatings which makes it very ecofriendly, other than this it enhances the performance of coatings and adhesives by increasing their adhesiveness and water resistance.
  • HPA plays a major role by contributing in the innovation of the industries such as automotives, construction and electronics as it pledges in development of new and improved products for these industries.
  • HPA causes many hazards such as irritation in the eyes and on skin upon contact. The repeated exposure of HPA may lead to dermatitis or other skin infections.
  • It can also cause problems in the respiration system of the body upon inhalation of the HPA vapors or mist such as coughing, throat irritation and shortness in breath, to avoid such problems it is crucial to minimize exposure to air bone particles.
  • HPA is highly flammable in nature and can cause dangerous explosive mixtures in air. It must always be stored away from all and any kinds of sources of ignition such as matches, fuels, lighters etc. It also must be handled in areas with proper safety measures.
