A new solution has been developed in the form of pre-dispersed masterbatches of core-shell particles in (meth)acrylate monomers. These new liquid toughener dispersions are stable and have been proven to increase the toughness of acrylic materials. The utility of these tougheners has been demonstrated in light-curable thermoset formulations and in 2K acrylic structural adhesives.
Polychloroprene has a long history in the world of adhesives. It has been the primary choice when fast, high-strength, and permanent bonds are needed in variety of applications, from shoe soles to foam bonding. Historically, polychloroprene adhesives have been solvent borne, but environmental and occupational safety reasons have recently caused a shift toward waterborne polychloroprene adhesives. One of the challenges in waterborne polychloroprene dispersion adhesives has been related to the thickening of these high pH systems, as well as the storage stability.
Although powder-based light stabilizers play an important role in modified silane sealants, they can also cause the sealant to become darker or yellowish. A recently developed liquid technology can alleviate that problem.
A proprietary liquid light stabilizer series was designed specifically for modified silane sealants. Their liquid form enables these light stabilizers to be quickly mixed with liquid resin without extra heating, lowering energy costs and reducing the production time between batches while simultaneously improving the sealant’s weather resistance.
