    • RHEOBYK® -R 605
    • RHEOBYK®-R 605 by BYK is a liquid, rheology additive for plastic applications such as vinyl ester and gel coats to reinforce the rheological effectiveness of pyrogenic silica. It is used as a thixotropic-reinforcing additive in unsaturated polyester resins, epoxy and polyurethane systems that already contain pyrogenic silica or organophilic phyllosilicates (organoclays) as rheology additives. It reinforces the three-dimensional network structure of the silica or phyllosilicates through additional bridges, thereby enhancing the thixotropy. For this reason, it achieves sufficiently high anti-sagging properties with improved leveling and air release properties, even with low quantities of silica or phyllosilicates. In vinyl ester resins, it activates hydrophilic, pyrogenic silica. It can be used in various resins, including polyols, to prevent fillers settling during storage and to stabilize molecular sieves such as zeolite. The recommended level based on pyrogenic silica in vinyl ester resins is 20-50%, pyrogenic silica in other resins is 10-30%, organophilic phyllosilicates (organoclays) is 5-20% and inorganic fillers is 0.5-2%. It is listed in EINECS, TSCA, DSL, AICS, PICCS, IECSC, ENCS, NZIoC and ECSI. It is in line with Directive 2011/65/EU (EU RoHS 2), as amended by the Delegated Directive (EU) 2015/863 (EU RoHS 3), EU Directive 2002/96/EC (WEEE), EU Directive 94/62/EC (Packaging Waste), CONEG Toxics in Packaging. It complies with REACH Regulation (EC) No 1907/2006. The shelf life of this product is 60 months.
    • Solution of polyhydroxycarboxylic acid amides. Acts as a rheology modifier and filler. It increase hydrogen bonding when combined with hydrophilic fumed silica or organically modified clays resulting in good anti-sagging properties with improved flow and deaeration. Its low dosages stabilizes fumed silica in laminating resins and help prevent separation during resin storage. In polyols it is used to stabilize molecular sieves like zeolith. Used as thixotropy enhancing additives in unsaturated polyester, epoxy and vinyl ester. It can also be used in filled systems to prevent or reduce the sedimentation of fillers during storage. Its recommended levels are 20 - 50% fumed silica in vinyl ester resins, 10 - 30% fumed silica in other resins, 5 - 20% organically modified clay in unsaturated polyester and 0.5 - 2% inorganic fillers in base resin.
