An overview
Chartwell Advantages
- Stable in humid environments. Soluble and stable in aqueous products. Will not polymerize like silanes.
- Cost is typically lower than silanes and other adhesion promoters
- Can be used in both water and solvent based products
- At normal use level products are INDEFINITELY STABLE over the pH range 4-10
- 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, 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
