  • Best Practices for 3M LC1211

    *See Terms of Use Below

    1. Application

      Dispense adhesive from syringe, fixture parts to be bonded, expose to suitable light source. Degree of cure will depend on exposure time, intensity and spectral distribution of the light source, distance of adhesive from the light source, and light transmittance of the substrates. Cure of surfaces exposed to oxygen may be inhibited resulting in a slightly tacky surface. Curing with high intensity short-wave UV light or covering the surface to exclude oxygen is suggested for a tack-free surface.
