Loctite® 4902™ and 4903™ Bond Reliably to Many Substrates and Offer ISO 10993 Biocompatibility

Rocky Hill, Conn. -- Henkel Corporation has developed two new highly flexible instant adhesives, Loctite® 4902™ and Loctite® 4903™, that offer elongations up to 155% and provide high-strength bonds in seconds. Both cyanoacrylate adhesives bond reliably to plastics, rubbers, metals and other substrates and offer ISO 10993 biocompatibility for use on disposable medical devices.

These one-part, low-viscosity instant adhesives flow easily onto any substrate and typically fixture to handling strength in 5 seconds or less. Loctite® 4902™ is the more flexible of the two, with an elongation of 155% and a modulus of 57,900 psi. Loctite® 4903™ offers 85% elongation and a modulus of 78,100 psi. In comparison, conventional cyanoacrylates offer limited elongations of less than 2% and moduli of  greater than 200,000 psi.

Loctite® 4902™ and Loctite® 4903™ are designed for use on close-fitting, flexible parts and can easily bond dissimilar substrates from plastics to elastomers. The flexibility of these new instant adhesives rivals those of acrylic and urethane adhesives.

Both adhesives are available in either 20-gram or 1-pound packages. Loctite® 770™ or 7701™ primers can be used to enhance bond strength on difficult-to-bond substrates such as polyethylene or polypropylene.

Adhesive sample

I am working with a customer who is looking for flexible adhesive. The customer's requirement is adhesive for sticker making purpose on vinyl or eco-solvent material. The adhesive should be crystal clear, without bubble resin, non yellowing, UV resistant and flexible so that sticker remains flexible.

If you have the right adhesive. Please, send to me a sample to my attention to the following address:
