  • Instructions For Use

    Primer Mix

    1. Premix 25 parts of Ethanol with 25 parts of DI water
    2. Add slowly with agitation 50 parts of Primer 5-017
    3. Slowly add 1.5 parts Crosslinker A with agitation
    4. 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

    1. To 10 parts water add 1-3 parts Crosslinker B with good agitation
    2. Mix well, there should be no lumps of coagulated material. It should look like milk
    3. Add 1 part Crosslinker A and mix well
    4. Add 100 parts of Hydrophilic urethane 8-3C with agitation.
    5. 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.

    Dry Slip coatings, Block resistant coatings

    1. Into a suitable container weigh 100 g of the hydrophobic dry slip of block resistant coating
    2. Place the coating container under mild agitation (no foam inclusion) and add slowly dropwise 3 g of Crosslinker A
    3. Mix for 5 minutes minimum. Coating can be used for up to 48hours.
    4. Dilute as needed

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

    Basic drug delivery coatings

    1. To 10 parts water add the drug amount appropriate for the batch size and end use. A small amount of cosolvent with no active hydrogens may help this dissolution. Adjust pH as needed to 8+ with tri ethyl amine
    2. If desired, add 1-3 parts Crosslinker B with good agitation. Crosslinker B will bind with active hydrogens over time and should be used sparingly, if at all, if these are the active functions
    3. Mix well, there should be no lumps of coagulated material. It should look like milk
    4. Add 1-2 part Crosslinker A and mix well Crosslinker A is reactive with acidic functions on the drug so consider this in your formulating.
    5. Add 100 parts of Basic drug delivery coating with agitation.
    6. 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.

    Antimicrobial Coating

    1. To 10 parts water add 1-3 parts Crosslinker B with good agitation
    2. Mix well, there should be no lumps of coagulated material. It should look like milk
    3. Add 1 part Crosslinker A and mix well
    4. Add 100 parts of Antimicrobial coating with agitation.
    5. Mix well, dilute as needed with water or a mix of 75% water/25% or less MEK.Level of the antithrombogenic coating may be reduced with addition of base hydrophilic coating.

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

    Antithrombogenic Coating

    1. Into a suitable container weigh 100 g of the antithrombogenic coating.
    2. Place the coating container under mild agitation (no foam inclusion) and add slowly dropwise 3 g of Crosslinker A pH should be maintained at or above 8 with ammonia
    3. Mix for 5 minutes minimum.
    4. Dilute as needed. Level of the antithrombogenic coatingl may be reduced with addition of base hydrophilic coating. Do not use Crosslinker B with this coating as it will become deactivated with ammonia.

    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 Crosslinker 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.
