OPTIGEL WH is produced from natural, colloidal aluminum silicate by a unique process. The high purity and consistent viscosity of OPTIGEL WH are made possible by our selective mining and rigid process control from the crude ore to the finished product. OPTIGEL WH is thixotropic in nature. It is most beneficial when it is used in combination with other rheological additives to produce the desired rheological properties in a paint system. Suitable co-thickeners include cellulosics, alkali swellables, and urethane thickeners

BYK-MAX NU 4230 LDPE is a granulated nucleation agent based on LDPE to increase the crystallization speed and amount of sperulithes in the polymer.

BYK-1691 SD is a VOC- and silicone-free, polymer-based defoamer formulated for mineral-bound construction materials. This high-efficiency, free-flowing powder enhances leveling properties and provides long-lasting defoaming effects, ensuring optimal surface quality even at low dosages across diverse mineral binder systems.

BYK-1692 SD is a versatile, VOC- and silicone-free powder defoamer designed for aqueous, mineral-bound building materials. With excellent compatibility across binder systems, it effectively reduces air voids, enhancing surface quality and strength in dry-mix mortars and construction chemical products.
