Question:We use a UV adhesive/coating for assembling the plastic and metal components of a complex medical device. We need to optimize our curing process and ensure that the adhesive is fully cured with maximum properties. What are the most important factors?
Answer: You’ll want to consider several important factors. The two parts of any UV system are the adhesive/coating itself and the UV curing lamp. First, you need to work with your supplier to find out the recommended cure conditions, including bulb intensity, time of irradiation and depth of cure in a certain time. The supplier should be able to tell you the important properties to measure to ensure full cure, such as hardness of the cured product.
