AFCONA 7909 is a block polymer with acidic functionality that is recommended for use in unsaturated polyester, epoxy, and polyurethane resin systems, particularly those with high filler loads such as ATH and artificial marble systems. It has excellent viscosity depressing properties.

AFCONA 8530 is a wetting and dispersing additive for solvent-based paints. Its acidic group provides excellent anchoring of inorganic pigments and matting agents. Its linear structure helps to reduce the viscosity of filler and extender dispersions. It is specifically designed for PVC, UPE, and PU foam systems, aiding in the dispersion of fillers and inorganic pigments while providing good viscosity reduction.

AFCONA 7525 is a block polymer with acidic functionality and viscosity-depressing properties. It is recommended for use in unsaturated polyester, PVC, epoxy, and polyurethane resin systems and is primarily used as a wetting and dispersing agent in highly filled systems, providing strong viscosity-depressing properties. It has excellent wetting and dispersing properties with pigments and functional fillers such as ATH, resulting in very low viscosity.

AFCONA 7530 is specifically designed for rheology control and is recommended for use in unsaturated polyester, PVC, epoxy, and flexible PU compounding applications. It contains hydroxyl, carboxylic, amine and amide groups, which form a hydrogen bonding network that leads to improved rheology control.

AFCONA 7510 is a block polymer with acidic functional groups that has viscosity-depressing properties. It is recommended for use in unsaturated polyester, PVC, epoxy, and polyurethane resin systems, and is especially effective in highly filled systems. It is especially suitable for applications involving ATH systems or artificial marble.

AFCONA 7472 is a polymer with high pigment affinity, making it ideal for use as an anti-separation agent between different polymers such as PS (polystyrene) and/or SBS (styrene butadiene rubber) and the unsaturated polyester binder in SMC, BMC, and TMC systems. It can also be used as a wetting and dispersing agent for extenders and pigments.

AFCONA 7520 is a block polymer with acidic functional groups that has the ability to reduce viscosity. It is recommended for use in UPE, PVC, epoxy, and polyurethane resin systems, and is especially effective in high-filled systems, such as those used in the artificial marble industry.

AFCONA 7480 is a high molecular weight polymer with high pigment affinity, recommended for use in unsaturated polyester, PVC, epoxy, and polyurethane resin systems. It is mainly used as a wetting and dispersing agent, anti-settling agent, to prevent floating, and to stabilize dispersed pigments.

AFCONA 7476 is a dispersant with high affinity for acidic and neutral carbon blacks, fiberglass, and other pigments. It is suitable as a dispersing agent for unsaturated polyesters (SMC, BMC, TMC, and pigment concentrates), PVC, epoxies, and polyurethane foams, providing excellent wetting to the glassfiber for faster wetting of resin to the fiberglass and better bond strength and performance in the final product. It is suitable for all types of pigments, from inorganic to organic, as well as carbon black.

Afcona - 5244 is an anionic/cationic wetting and dispersing additive designed to enhance the wetting of pigment surfaces and organically treated Bentonites.

Afcona - 7476 is a dispersant with high affinity towards acidic and neutral carbon black, fiberglass, and other pigments.

Wetting and dispersing additive with anti-settling properties for use with ambient cured unsaturated polyester and vinyl ester resins.

USI Chemical Silane USi-1301 functions as a surface modifier in fillers and pigments, where it improves the dispersibility of the filler and the mechanical properties - such as flexural strength, tensile strength and modulus of the composites. The silane also has its application as an adhesion promoter in formulations and primers & reduces the filler's sedimentation tendency in the uncured polymer. USi-1301 also greatly increases water (vapor) and corrosion resistance.

Nanjing Union Silicon Chemical Amino Silane USi-D1301 appears as colorless transparent liquid.

USI Chemical Silane USi-1302 functions as a surface modifier in fillers and pigments, where it improves the dispersibility of the filler and the mechanical properties such as flexural strength, tensile strength and modulus of the composites. The silane also has its application as an adhesion promoter in formulations and primers & reduces the filler's sedimentation tendency in the uncured polymer. Silane USi-1302 also greatly increases water (vapor) and corrosion resistance.

EMFutur EM100003 is the amine groups of our aminated graphene oxide improve its dispersibility in various polymer matrices (epoxy resins, polyester resins, polymers and others). The key to improving the mechanical properties lies in the homogeneous dispersion of the filler in the matrix. It has been demonstrated in the literature that amine functionalisation is a successful approach to achieve this.

WARADUR® E is an ester wax consisting of esters of montanic acids with multihydroxyl alcohols. Montanic acids are straight-chained monocarboxylic acids with a chain length in the range of C28 – C32. The corresponding esters exhibit chain length in the range of C58 – C66 and provide this wax with a low volatility, good thermostability and low migration rates.
