Chartwell
Advantages |
| 1. |
Stable in
humid environments. Soluble and stable in aqueous products.
Will not polymerize like silanes. |
| 2. |
Cost is often
<50% of silane and most other adhesion promoters |
| 3. |
Can be used
in both water and solvent based products |
| 4. |
At
normal use level products are INDEFINITELY STABLE over
the
pH range 4-10 |
| 5. |
Non-flammable,
non-corrosive; non-toxic metals |
|
|
|
Chemical Descriptions |
|
Unique compositions based upon proprietary
stabilized non-toxic metal(s) and other proprietary organofunctional
components supplied as solutions in water, ethylene glycol, propylene
glycol, diethylene glycol, and dipropylene glycol. |

Applications |
|
Coatings |
|
· Use in all industrial solvent based and water
based coatings
· Compatible and stable (as post add) with aqueous
coatings (pH4-10)
· Improves adhesion to metals, concrete, plastics,
etc.
· Improves humidity resistance
· Improves corrosion resistance/ creep at scribe
· Improves pigment dispersion of carbon black, phthalo,
and others
Competition:
Silanes and other adhesion promoters |
|
|
Inks |
|
Improves adhesion of aqueous
and solvent-borne inks (acrylics, etc.) to plastic film including
treated polyethylene and treated polypropylene |
|
|
Rubber |
|
· Superior adhesion to metal, rubber and other
synthetic surfaces, including PVC, polyurethane
and others
· Improved abrasion resistance
· Increased tensile and tear strength
Competition:
OSi A-189, Degussa Si 69 |
|
|
Adhesives |
|
·
Improves adhesion to metals, plastics, and rubbers
· Useful in water-borne industrial adhesives
· Useful in rubber, epoxy, polyurethane and similar
adhesive systems
Competition:
OSi A-1100, A-1120, A-186, A-187 |
|
|
Abrasives |
|
Improves wear resistance and
durability
Competition:
Thermoplastic OSi A-1100 |
|
|
Thermoplastics |
· Improves pigment/ filler dispersion
· Iimproves physical strength properties of mineral
filled composites |
