BYK® -9077

BYK® -9077 by BYK is a solvent-free wetting and dispersing additive for ambient curing resin systems, PVC plastisols, SMC and pultrusion. It does not contain plasticizers. It is recommended for stabilizing organic pigments and particularly basic carbon blacks. For ambient curing resin systems, it deflocculates pigments by means of steric stabilization. It also generates a uniform electrical charge in the pigment particles. The resulting repulsion effect and the steric stabilization prevent any co-flocculation which leads to non-floating coloring in pigment blends. As a result of the small particle size of the deflocculated pigments, high levels of gloss can be achieved and the color strength is improved. It offers reduced viscosity, increased transparency in transparent pigments and hiding power in opaque pigments. It also improves the flow characteristics and a higher pigment load is possible. It can also be used to improve the wetting of carbon fibers. It brings about a greater process reliability. For thermoplastics, BYK® -9077 significantly reduces the viscosity and brings about Newtonian flow characteristics in the millbase. It improves the torque build-up, the throughput, the viscosity (MVR), the filter pressure value (FPV), and the dispersion quality. It is used in thermoplastic compounds and color masterbatches based on PE, PP, ABS, PVC, PET and PA. The recommended level is 5-30 % additive (as supplied) based on organic pigments and carbon blacks for pigment stabilization and 0.5-1% additive based on the fiber content for wetting carbon fibers. The shelf life of this product is 36 months.
