The acrylic pressure sensitive adhesive has the unique function

The acrylic pressure-sensitive adhesive has the unique function of long-lasting antibacterial and expands its application in the field of medicine and health.

Pressure-sensitive adhesive is a viscoelastic body, only mild pressure can stick to the driest surface and part of the wet surface, and when torn off the adhesive is not easy to remain on the surface. Due to the advantages of convenient use, good stability, and easy preparation, the pressure-sensitive adhesive has been widely used in the medical and health fields such as surgical dressing, skin wound treatment, adhesive biomedical devices, transdermal drug release patches, medical labels, and tapes.

Acrylate is the main material for the synthesis of medical pressure-sensitive adhesive, which has two advantages:

1. The preparation of acrylate pressure-sensitive adhesive does not need to add additional components, through emulsion or solution polymerization and can be used directly, without separation and purification, so it has a great cost advantage, and avoid potential safety problems;

2. Adjusting the content and type of acrylic monomer can get different properties of pressure-sensitive adhesive, so it has advantages in product diversity and flexibility. Since the pressure-sensitive adhesive is often used for covering the protection of skin wounds, it is necessary to give it antibacterial properties, which can prevent wound infection and facilitate wound healing.

Iodine is a common medical fungicide, usually used in iodine or iodophor solution. Iodophor granules dissolved in solvent acrylic pressure sensitive adhesive can be prepared to contain iodine pressure sensitive adhesive and has been prepared into iodophor surgical towel. However, due to the limited solubility of iodophor in the pressure-sensitive adhesive solution, the iodine-carrying capacity is not high.

Moreover, there is no chemical coordination bond interaction between iodophor and pressure-sensitive adhesive, so iodophor will be released quickly after being posted on the skin, and cannot play the role of slow release of iodine, so it cannot meet the requirements of long-term antibacterial. Therefore, a pressure-sensitive adhesive with high iodine content and slow release of iodine is needed to give acrylate pressure-sensitive adhesive a unique function of long-term antibacterial and expand its application in the field of medicine and health.
