Product Description
PC-3™
Smooth-On PC-3™ Laboratory Table Top Cement is a two-component, black epoxy resin compound designed to join, bond and caulk sections of laboratory counters and tables. This epoxy resin cement is heavily filled and will adhere to vertical surfaces without sagging. It cures at room temperature with extremely low shrinkage.
duoMatrix™-G
duoMatrix™-G is a new three component polymer additive system that greatly enhances the physical properties of alpha gypsum products duoMatrix™-G (Matrix-G™ for short) reduces the demold and drying time of gypsum and drastically reduces water permeability making it suitable for both interior and exterior applications (for exterior use, product must be sealed – see “post finishing” section). Matrix™-G has less odor and yields elements that are a brighter white than competing products.
