As a leading manufacturer of advanced adhesive solutions for the medical industry, Henkel has launched a novel medical grade light cure adhesive, Loctite WT, designed for devices that are worn on the body without causing skin irritation.
The newly developed adhesive is available in two different grades. Loctite WT 3001 and Loctite WT 3003, Henkel states, have both been tested according to ISO 10993 standards, ensuring a high level of safety and performance for users. The solutions have also been tested for skin sensitisation, making them suitable for a wide range of medical applications including wearable devices.
The new product is formulated without IBOA (Isobornyl Acrylate), known in the medical community for causing patient skin reactions when used in wearables, or any other known skin sensitising monomers. The adhesive is also formulated to conform to EU MDR 2017 regulations concerning use of CMR (carcinogenic, mutagenic, or toxic for reproduction) substances in medical devices making it a robust option for new designs.
“At Henkel, we are committed to providing our customers with innovative adhesive solutions that meet the highest safety standards,” says Philipp Loosen, vice-president and head of industrials EIMEA and global key accounts medical at Henkel. “With the introduction of our new medical grade wearable device light cure adhesive, we are addressing the growing need for safe and effective adhesives in the medical industry. Our adhesive is ISO 10993 tested and formulated with patient comfort and safety in mind, ensuring its suitability for use in medical device bonding and medical wearables.”
Henkel's wearable device light cure adhesive offers various benefits for medical applications. Its light cure capabilities allow for quick and efficient bonding, reducing production time and increasing productivity. The adhesive also provides good adhesion to a wide range of substrates commonly used in medical devices and wearables, ensuring robust bonding and sealing performance after drop impact or bathing.
“The adhesive's formulation meets FDA & EU MDR recommendations for wearable medical devices regarding sensitising and CMR ingredients,” states Henkel. “Henkel is committed to meeting regulatory requirements and delivering safe and reliable adhesive solutions to its customers. The focus on removing all known skin sensitising monomers further reduces the risk of skin sensitisation, making the adhesive suitable for prolonged skin contact in medical applications.”
