What Are the Two Basic Types of Light-Curable Materials?

In the 1960s ultraviolet (UV) light-curing technology was originally developed as an alternative to solvent-based, heat- and air-drying processes and slow-curing silicones, epoxies, urethanes, pressure-sensitive tapes, cyanoacrylates, modified...

Sterilized Aluminum Bonding

"We have an application in which a 0.5" x 0.5" x 1" square bar is inserted a depth of 0.5" in a 0.5" x 0.5" square hole machined on a flat bar. Both parts are made of anodized 7075 T6 Aluminum alloy.  The 0.5" x 0.5" x 1" is receiving intermittent torque...

What epoxy can I use to bond polycarbonate that will be autoclaved?

"I want to find an epoxy that can bond two pieces of polycarbonate materials and be sterilized using autoclave. We tried using epoxy 353ND from Epoxy Technology but it is very difficult to cure completely, and after the sterilization process, the epoxy...

Low-Viscosity Epoxy for Adhering Ceramic to SS

"I am interested in a low-viscosity epoxy (<100 cp) with good adhesion to ceramics and stainless steel. The objective is to seal a small metal sensor inside a ceramic casing at room temperature. There is no contact with the patient. What type of epoxy do...

What adhesive will withstand Sterrad H202 plasma processes?

"We use two-part epoxies and UV-curable cements to seal Viton- or PVC-bending rubber onto the distal end of flexible endoscopes. Our current epoxy works well when it is sterilized using Steris or glutaraldehyde solutions. With the introduction of Sterrad...

What adhesives are compatible with mineral oil?

"Do you have a list or can you point me to a list of adhesives and epoxies that are compatible with mineral oil? These would be ones that do not break down or release their adhesiveness when mineral oil passes over the adhesive/epoxy. Along those lines,...

Mechanical Properties of UV Adhesives

"In my application I have a process where I apply UV adhesive between two pieces of plastic and I am seeing a short contraction period followed by a longer expansion period. Is it possible for UV adhesive to behave this way? How much does UV adhesive...

Gap Filling Optical Adhesives/Epoxies

"I need an epoxy to join two BK7 glass parts together. Gap is around 0.2mm. Light will cross the interface. Reasonable index match to the glass required. Low stress/shrinkage so it doesn't distort the parts please. Viscosity not too runny, as we want it...

Light/UV Curing Through Polymers

"I have an application where we would like to cover the edge of a silicon die (that has been first tacked in place with epoxy that has been cured to a Valox/PBT base) with an uncured epoxy. Then add additional epoxy to a second bond location that...
