Coatings Additives

Our CoatOSil* coatings additives and Silquest* silanes are excellent candidates to consider for an array of industries and applications, including water- and solvent-borne coatings, high solids inks, primers, and powder and ultraviolet/electron beam (UV/EB) cure coatings. These products can deliver advanced properties for applications such as automotive clear coats and refinish systems, coatings for transportation and aerospace, wood coatings, protective coatings for flooring, marine, coil, industrial maintenance, and other demanding applications.

Our CoatOSil coatings additives offer multiple advantages to enhance the appearance and longevity of coated surfaces, including increased substrate wetting, mar resistance and gloss retention, as well as excellent chemical, UV and corrosion resistance. Their enhanced flow and leveling properties also help to eliminate defects in finish surfaces. 

CoatOSil coatings additives, as well as our Silquest silanes, can provide moisture-initiated crosslinking in properly modified resins for coatings and inks, as well as offer improved wet adhesion, chemical and corrosion resistance, weatherability, pigment dispersion, and scrub resistance. CoatOSil coatings additives and Silquest silanes may also enhance the durability of coatings by delivering improved thermal stability, creep resistance and hardness.

CoatOSil 1211C coatings additive is a 100% active, organomodified silicone that typically does not interfere with recoatability. CoatOSil 1211C coatings additive may be an effective replacement for fluorosurfactants in many applications, as it typically does not cause the foaming problems often associated with fluorosurfactants. It may also be considered for use in solvent-based and radiation-curable coatings, where its use can enhance the wetting power of the coating formulations.

In addition, CoatOSil 1211C coatings additive typically: 

  •  Enhances coatings' uniformity
  •  Does not cause foaming in waterborne coatings or inks
  •  Does not affect recoatability in internally tested systems
  •  Improves dispersion stability of pigments and color acceptance

Silquest A-1170 Silane

Get Latest Price

Amino bis-silanes such as Silquest A-1170 silane can be effective in reacting with epoxy, urethane, melamine, polyimide, phenolic and furan thermosetting resins, as well as many thermoplastics, such as polyamides and polyesters. Silquest A-1170 silane offers a fast cure time and/or rapid adhesion build. Because of its higher purity grade, Silquest A-1170 silane is an excellent candidate to consider for use in applications that demand low color and greater control of reaction stoichiometry. Silquest A-1170 silane is a versatile silane, and it may be added directly to polymers during system formulation or used independently as a primer.

Silquest A-2120 Silane

Get Latest Price

Silquest A-2120 silane also helps promote excellent adhesion to inorganic substrates, such as metal and glass, and plastics, particularly when combined with SPUR * prepolymer adhesives or sealants. In addition to inorganic and plastic surfaces, Silquest A-2120 silane also can improve adhesion to inorganic fillers or reinforcements for a variety of sealants. As a difunctional silane, it can provide as much as a 35% improvement in elongation and superior stability in waterborne systems over trifunctional amino silanes. With polyamino functionality, Silquest A-2120 silane helps provide a reliable reactive site for amino-reactive resins and offers good wetting of substrates.

It is an excellent candidate to consider for use in RTV silicones and hybrid silane-crosslinked sealants to strengthen adhesion to glass, steel, aluminum and concrete substrates. Silquest A-2120 silane can also enhance adhesion of polysulfide sealants to glass, aluminum and steel.

Silquest Y-9627 Silane

Get Latest Price

With its bis-silyl functionality, Silquest Y-9627 silane may demonstrate greater bonding and adhesion promotion in many instances than more common silanes. As a secondary amino bis-silane, it may be considered for use as a silane reactive endcapper in select systems. As a methoxy silane ester, Silquest Y-9627 silane is fast-acting, enabling formulations to cure and build adhesion quickly.  

Silquest Y-9627 silane has proven effective when reacting to epoxy, urethane, melamine, polymide, phenolic and furan thermosetting resins. It also can interact with thermoplastics, including polyamides and polyesters. Durable, water-resistant bonds typically are achievable when the silyl portion of Silquest Y-9627 silane is condensed with an inorganic surface and covalent bonds are formed with the resin matrix in composite, paint, adhesive and sealant applications.
