Product features and advantages
VOK ®- Disper 2008 is a wetting and dispersing agent specially developed for dispersing silica type matting powder in solvent-free UV coatings and high solid systems. It is usually used for wood and furniture coatings and industrial coatings. VOK ®- Dispatch 2008 is a product synthesized using controlled polymerization technology (CPT). Because it contains alkaline pigment affinity groups, it is suitable for most types of silica matting powder, and can work on matting powder with or without surface treatment. Even at low dosage, the additive can also improve the dispersion and stability of matting powder. It can greatly reduce viscosity and has a good directional effect on matting powder. VOK ®- Disper 2008 has good compatibility with many polymers and monomers, which can produce good matting effect even when using conventional silica matting powder.
Recommended dosage
3-15% of auxiliary dosage (purchase form) is based on matting agent.
The above recommended dosage is for reference, and the appropriate dosage shall be determined through a series of tests. In order to obtain good matting effect and reduce viscosity, the amount of auxiliary agent should be adjusted according to the surface characteristics of silica matting agent.
Adding method and processing guidance
Wetting and dispersing additives should normally be added to the abrasive, only in this way can the additives be fully effective. Pre mix the resin and solvent components in the abrasive, and then slowly add the auxiliary agent in the state of stirring.

Product features and advantages
VOK ®- Disper 2008 is a wetting and dispersing agent especially suitable for UV adhesives filled with silica, which is synthesized by controlled polymerization technology (CPT). Because it contains alkaline pigment affinity groups, it is suitable for most types of silica and can act on hydrophilic or hydrophobic silica. Even in the case of low dosage, it can also improve the dispersion and stability of silica. It can strongly reduce viscosity.
Recommended dosage
3-15% of auxiliary dosage (purchase form) is based on matting agent.
The above recommended dosage is for reference, and the appropriate dosage shall be determined through a series of tests.
Adding method and processing guidance
Wetting and dispersing aids should usually be added before silica, only in this way can the aids be fully effective.
