Water-Based Acrylic Adhesive for Medical Tapes | High-Performance Bonding

Waterbased acrylic pressure sensitive adhesive for medical tapes is a specialized formulation designed for skin contact, prioritizing biocompatibility, gentle adhesion, breathability, and clean removability, critical for applications such as wound dressings, surgical tapes, and transdermal patches. Biocompatibility is ensured by using high-purity monomers (e.g., ethyl acrylate, 2-ethylhexyl acrylate) and avoiding irritants or sensitizers (formaldehyde, phthalates), with compliance to ISO 10993 standards for skin irritation and cytotoxicity. Adhesion is carefully calibrated to be strong enough to secure dressings during movement or moisture exposure (e.g., sweating) but gentle enough to remove without damaging skin or causing pain, achieved by balancing low-tack monomers and controlled crosslinking. Breathability (moisture vapor transmission) is enhanced by optimizing polymer particle size and film structure, allowing skin to breathe and reducing maceration (skin softening) under the tape. Water resistance ensures the adhesive remains intact during bathing or sweating, using hydrolysis-resistant monomers and crosslinkers, while still allowing removal with water or mild solvents if needed. The adhesive is formulated to be compatible with other medical materials (nonwoven fabrics, films) and sterilization processes (gamma radiation, ethylene oxide), maintaining performance post-sterilization. Low extractables (substances that leach into skin) minimize the risk of adverse reactions, with rigorous testing to ensure compliance with FDA, EU MDR, and other global medical regulations. Additionally, it offers consistent viscosity for uniform application during tape manufacturing, supporting reliable production of medical products that meet the stringent safety and performance demands of healthcare settings.
