Flash Rust Inhibitors

Coadd™ FR-355

Colorless to light yellow liquid

45±1

0.3~2.0

Modified organic chelating agent. Forming passivating layer on the metal surface to prevent the electro-chemical flush rust by water. At the same time it can improve the anti-corrosion properties of the paint film. The product is VOC-free, and applicable in all formulations.

Coadd™ FR-365

Colorless to light yellow liquid

45±1

0.3~2.0

Modified organic chelating agent. Forming passivating layer on the metal surface to prevent the electro-chemical flush rust by water. At the same time it can improve the anti-corrosion properties of the paint film. The product is VOC-free, and applicable in all formulations.

Coadd™ FR-358

Colorless to light yellow liquid

45±1

0.5-2.0

A flash rust and corrosion inhibitor specfically for water-borne metal coatings. It is an enviromental-friendly product, not containing nitrite nor amine ingredients. Though special molecular designs, the product forms passivate layer on the metal surface after added to the paint formulation and then coated, thus prevents the formation of flash rust. It also has some function in corrosion inhibition and thus improves the anti-corrosion property of the paint films.

Coadd™ FR-359

Colorless to light yellow liquid

45±1

0.3-2.0

Flash rust inhibitor with good economic values for water-borne metal coatings, containing organic chelating polymer. It will form dense passivate layer on the metal surfaces when being added into the water-borne metal coating formulations, to effectively prevent teh occurance of flash rust. The product also some some property in corrosion inhibition.

Slippery Agent

Coadd™ S-820

Milky white liquid

60±1

0.5~5.0

Modified silicone polymer with excellent slippery enhancment and compatibility. Improving the surface hardness of the paint films. Also imrpoving the water resistane and hydrophobic property of the paint films. Generally used for water-borne pigmented coatings.

Corrosion Inhibitors

Coadd™ CR-366

Colorless to light yellow liquid

40±1

5.0~10.0

The product can greatly improve the paint properties in salt-spray and anti-corrosion, by enhancing the film density and its adhesion to metal surface.Thw use of the additive can partially or entirely replace the coalescent in the paint formulations.It also improves the drying speed of the paint films.

Adhesion Promoters

Coadd™ A-1001

Colorless transparent to semi-transparent liquid

100

0.2~0.5

The product greatly improves the adhesion of base coat to the substrates such as cement, glass, and metals. Very good formulation compatibility. No cratering and no impact on flim clarity. Quite strong penetrating effect.Suitable for applications in coatings, inks, and adhesives.

Coadd™ AP-054

Light yellow to yellow transparent liquid

100

0.2~2.0

Effectively improving the adhesion between paint film and metal substrates. The product contains functional groups reactive with such metals as iron, aluminum, and nickel, as well as functional groups compatible with polymer resins, therefore can promote the adhesion between polymer and metal substrates.The product can also improve the substrate wetting. The product is a water-soluble oligomer,very suitable for water-borne metal coatings and aqueous inks.

Curing Agents

Coadd™ C-2600T

Colorless to light yellow transparent liquid

100

Water-dispersible high gloss PU curing agent. NCO content is 18%. It has very good aqueous dispersion effect. High reactivity. Fast hardness buildup. And ecellent water resistance. Suitable for water-borne two-pakc hydroxyl acrylic and PUD systems.

Coadd™ C-260

Colorless to light yellow transparent liquid

100

Water-dispersible high gloss PU curing agent. NCO content is 21%. It has very good aqueous dispersion effect. High reactivity. Fast hardness buildup. And ecellent water resistance. Suitable for water-borne two-pakc hydroxyl acrylic and PUD systems.

Coadd™ C-2500A

Light yellow transparent liquid

48±1

Aqueous organic amine curing agent for water-borne epoxy two-pack systems. Long pot life and fast late hardness buildup. Can be used for water-borne liquid and solid epoxy formulations. No impact on water resistance . No water whitening of the paint films.

Anti-settling Agents

Coadd™ AS-710

Yellow transparent liquid

40±1

1.0~5.0

Organic nonionic PU chemistry with fairly strong function of self-association, effectively preventing the settlement and phase separation of pigments and fillers. Minimal impact on property of water resistance. Strong thixotropic characteristic, effectively preventing sagging and dripping, especially good for coatings with high requirement on film thickness.

Al powder Orientating Agent

Coadd™ SC-2

Mikly white liquid

30±1

1.0~5.0

Used for industrial coating formulations containing aluminum slurries, to prevent the settlement of Al slurry and improve the Al orientation during the flim drying process. Very good encapsulation effect with Al slurries to improve Al packing and increase the gloss and hardness of the paint films.

Formaldehyde abatement additive

Coadd™ FA-6

White to light-yellow milky liquid

55

1.0~1.5

Coadd™ FA-6 removes formaldehyde effectively through chemical reactions, and can be added into any aqueous formulations. Particularly suitable for interior coating products. Meet the JC/T1074 national standards on indoor air purification with interior coating materials.

Coadd™ FA-7

White to light-yellow milky liquid

100

1.0~1.2
