Adhesion Promoting Coatings (tiecoats)

• Forms and adhesion promoting interface between the substrate (plastic or metal) and the coating

• Forms and adhesion promoting interface between two layers of organic coatings

• Enhances long-term adhesion durability

• Enhances long-term weatherability

• Allows lower cure temperatures for heat-cured coatings such as polysiloxanes without adversely affecting adhesion durability

• Stabilizes adhesion issues with additives migrated to the surface such as internal mold release, UV absorbers, flow control agents, surfactants, colorants, anti-static agents, and fire retardants

• Supplied at 5% to 40% solids in solvents or water and/or combination of solvents/water

• Thickness variations:  0.5 to 25 microns depending on application and solids content

• Applied by dip, flow, spin, spray, and flow coating methods

• Curing conditions:  Thermal, UV or ambient cure

• Cost effective

• Custom formulated and freshly manufactured to order

• Supplied from 1 to 55 gallons

  Applications:  To promote coating adhesion between plastic, glass, and metallic substrates, to allow lower cure temperatures with no adverse effects on coating adhesion, to promote coating adhesion to low energy surfaces.

PRIMERS

• Based on various organic and organometallic coupling agents

• Applied by wiping, spin, spray, and flow coating methods

• Impart a thin, chemically reactive surface

  o   Forms a near monomolecular layer

  o   Leads to the formation of a covalent, ionic, or hydrogen bonds between the substrate and the coating

• Enhances substrate surface energy

  o   Improves wetting

  o   Leads to enhanced coating adhesion and cosmetics

• No effect in increasing coating thickness

• Supplied at 1% to 5% solids in solvents, water, or combinations of solvents and water

• Must be used at minimum concentration to avoid loss of clarity and cosmetic defects

• Curing conditions:  ambient

• Cost effective

• Custom formulated and freshly manufactured to order

• Supplied from 1 to 55 gallons
