Techsil has developed a clear, epoxy adhesive called EP25880 Clear that cures fast and provides a strong, tough and durable bond on carbon fibre composite parts.
“I have been working with a number of companies that were manufacturing and assembling products made of composite materials and a need arose to find a product that could bond carbon fibre parts quickly and neatly,” Techsil’s Application Engineer Steve Green explains. “There are expensive adhesives on the market but these were reported to be not that easy to work with. Techsil was able to develop a bespoke cost effective 1:1 epoxy formulation that is clear and cures in 5 minutes.”
“In tests, two carbon fibre parts were ‘butt joined’ and a bench weight test of 56 lb was applied for 30 minutes and didn’t trouble the joint at all,” he continues. “The part was then cleaned down and the joint line was found to be aesthetically acceptable."
Techsil EP25880 Clear is a two-component multi-purpose epoxy adhesive said to be ideal for bonding various substrates including carbon fibre, wood, ceramics and metals. It cures to a completely water-clear product with a Shore Hardness of 80D, a shear strength on steel over 20 MPa and tensile strength on steel of over 30 MPa.
Techsil has just launched this product to the wider market and hopes it will prove of interest to other manufacturers of products made of composite materials.Tech

Do you enjoy a cross-country ride on your bike on the weekend? Wouldn’t you appreciate a bike with higher performance and with safer and longer lasting rims? And ideally not at a jaw-dropping price. Graphene in the form of graphene nanotubes has shown huge potential for enhancing the properties and reducing the weight of bicycle wheel rims.
