Questions

  1. Hi, is it LR white acrylic resins catalysed or are you sending catalysator with resin as a powder? is it electron microscopy grade? thank you

    1 answer
    1. L9774 is provided as an uncatalyzed version along with the benzoyl peroxide catalyst (Catalog Number B5907) necessary to activate the LR white acrylic resin. The benzoyl peroxide is blended with dicyclohexyl phthalate to make B5907 safe to transport. L9774 is not stated to be electron microscopy grade, although the expectation is electron microscopy is probably the most common use for the L9774.
