  • Best Practices for Dymax Multi-Cure 605

    *See Terms of Use Below

    1. Surface Preparation

      All bond surfaces should be clean and free from grease, mold release, or other contaminants prior to dispensing the adhesive.

    2. Curing

      Full cure is best determined empirically by curing at different times and intensities, and measuring the corresponding change in cured properties such as tackiness, adhesion, hardness, etc. Full cure is defined as the point at which more UV exposure no longer improves cured properties. Higher intensities or longer cures (up to 5x) generally will not degrade Dymax light curing adhesives.

      SECONDARY HEAT CURE: Heat can be used as a secondary cure mechanism where the adhesive cannot be cured with light. Light curing must be done prior to heat cure.

      ACTIVATOR CURE: Shadowed areas can be cured with activator., Activator is placed on one surface and the adhesive on the mating surface. Curing takes place at room temperature when the parts are mated. Activator requires closely mated parts (up to 0.5 mm [0.02 in] gap). Closely mated parts fixture (achieve handling strength) in less than a minute.

      This product cures with exposure to UV and visible light. Exposure to ambient and artificial light should be kept to a minimum before curing. Dispensing components including needles and fluid lines should be 100% light blocking, not just UV blocking.

      Cure speed is dependent upon many variables, including lamp intensity, distance from the light source, required depth of cure, bond gap, and percent light transmission of the substrate.

      Oxygen in the atmosphere may inhibit surface cure. Surfaces exposed to air may require high intensity (>100 mW/cm2) UV light to produce a dry surface cure. Flooding the bond area with an inert gas, such as nitrogen, can also reduce the affects of oxygen inhibition.

      Parts should be allowed to cool after cure before testing and subjecting to any loads.

      In rare cases, stress cracking may occur in assembled parts. Three options may be explored to eliminate this problem. One option is to heat anneal the parts to remove molded-in stresses. A second option is to open the gap between mating parts to reduce stress caused by an interference fit. The third option is to minimize the amount of time the liquid adhesive remains in contact with the substrate(s) prior to curing.

      Light curing generally produces some heat. If necessary, cooling fans can be placed in the curing area to reduce the heating effect on components.

      At the point of curing, an air exhaust system is recommended to dissipate any heat and vapors formed during the curing process.

    3. Clean-Up

      Uncured material may be removed from dispensing components and parts with organic solvents. Cured material will be impervious to many solvents and difficult to remove. Clean up of cured material may require mechanical methods of removal

    4. Removal

      Remove material from skin with soap and water. Never use organic solvents to remove material from skin and eyes.
