Instructions for use
 
Primer Mix

Premix 25 parts of Ethanol with 25 parts of DI water

Add slowly with agitation 50 parts of Primer 5-017

Slowly add 1.5 parts Crosslinker A with agitation

Mix for 5 min. Minimum.

 

Coat by dip, wipe etc. Dry 5 minutes at 160 F or other suitable time/temperature profile before topcoating.

Topcoat hydrophilic

To 10 parts water add:

1-3 parts Crosslinker B with good agitation

Mix well, there should be no lumps of coagulated material. It should look like milk

Add 1 part Crosslinker A and mix well

Add 100 parts of Hydrophilic urethane 8-3C with agitation.

Mix well, dilute as needed with water or a mix of 75% water/25% or less MEK.

 

Coat by dip, wipe, etc. Dry for 1 hour at 160 F and at ambient for full properties to develop.

The water-based coatings you receive may be stored for up to one year at room temperature. Freezing and long periods at high temperatures may change their characteristics.
 
Mix well before using. Avoid aggressive mixing that will incorporate foam unless you will allow them to sit before use, or are planning to add solvents that will allow the foam to break. Note that some coatings containing particulate (Tungsten, Silver and platelet scratch protective) may require some agitation to prevent settling from occurring during application.
 
Use reasonable practices in handling these materials. Eye protection, adequate ventilation and protective garments and gloves are suggested.
 
" To avoid shock and coagulation in crosslinked coatings,it is best to mix the appropriate amount of crosslinker by dropwise addition to coating or diluent which is mixing. The agitation should be sufficient to immediately dispersed the crosslinkers added. Often solvents should be added in this manner as well if they are to be used. Check stability and homogeneity of the mix before use." Once mixed  these may be used directly or diluted and used per best application methods. Coatings prepared with Cross-linker B should not be diluted with ethanol. Pot life for the mixed coatings will depend on solids and ambient conditions. Generally speaking the lower solids and lower temperatures will yield longer pot lives. Crosslinkers, especially crosslinker B which will gel,  should be protected from atmospheric moisture. If needed for reuse outside the prepackaged material, they should be sealed under dry nitrogen purge.

Once these coatings have dried they will not re-dissolve and must be filtered to remove particulate formed during drying.

While wet, coatings may be diluted with water, ethanol, MEK or acetone to allow thinner coatings to be applied. Coating thickness can also be controlled by the removal speed when dipping (faster = thicker) and amount sprayed or deposited on the surface.

Please assure that appropriate handling precautions are taken for any systems resulting from dilution with solvent. Water is the first choice for clean up. Unless there is a hazardous material in the coating (once cross-linked into the dried coating, the cross-linkers are not considered hazards) these dried coatings may be disposed of as trash. Dispose of these materials according to local, state and federal laws.

If adhesion or surface wetting is inadequate, there are several steps that may be taken. Either the surface tension of the substrate may be increased with corona, plasma, acid or flame etching. Alternatively the surface tension of the coating may be reduced with surfactants (less desirable as the coating then becomes a different chemical composition) or solvents may be incorporated to dilute and wet.
