Amino Crosslinkers

Amino crosslinkers for outstanding results

Amino crosslinkers allow formulators to develop one component coatings with excellent formulated package stability that are heat activated to deliver optimal cure characteristics and finished properties. Alkylated urea and melamine amino resins are employed in both water and solvent-containing coating formulations for a variety of metal and wood coatings.
Alkyds, polyesters, acrylics and epoxies for coatings achieve their best properties when reacted with a crosslinking agent.
The most versatile amino crosslinker is CYMEL 303 LF which finds itself in coatings or paints for cans, cars, kitchen cabinets and furniture just to name a few.

Amino crosslinkers for automotive topcoats

Allnex offers a broad range of CYMEL® and SETAMINE® crosslinkers used in each layer of the auto OEM coating process.

For automotive topcoats they provide your applications with high film hardness and good chemical resistance plus they offer improved durability and allow for perfectly even finishes due to improved flow and leveling. 

The urea formaldehyde resin with the quickest cure speed of them all

Part of the CYMEL® product line is also the partially iso-butylated urea crosslinking resin CYMEL® UI-27-EI. This particular amino crosslinker excels in hardness and extremely high curing speed. The CYMEL® UI-27-EI can best be used in conversion varnish applications like cabinetry and wood furniture.

  • Extremely short curing time

  • Excellent film hardness

  • Suitable for industrial wood and metal

Searching for an HMMM-based product for rubber applications?

The CYREZ® amino resin crosslinker portfolio includes hexamethoxymethyl melamine (HMMM) based materials supplied in liquid or powder blend form and function as crosslinking resins in the tire and rubber compounding market.

Some of the advantages in using HMMM in comparison to the more conventional amino resins are that HMMM is available at a near 100% non-volatile content and offers improved performance.

Our CYREZ® 963 product family is a portfolio of HMMM liquid resins and our CYREZ® 964 as well as our CYREZ® CRA 200-300 product family are carried by precipitated silica.

  • Adds remarkably stable and resistant finish

  • Offers improved film flexibility

  • Near 100% non-volatile content

Versatile Acid Catalysts for Coating Formulations

In addition to amino crosslinkers, allnex offers CYCAT® acid catalysts to accelerate the cure speed of coating formulations for applications from coil to wood and everywhere in between.
CYCAT® 6051 is an extremely hydrophobic acid catalyst based on dinonylnaphthalene sulfonic acid supplied at 50% active in n-butanol used in coil coatings. It is an oil soluble sulfonic acid that gives excellent humidity resistance in high bake amino and phenolic systems. CYCAT® 6051 advantages:

  • Maximum water resistance

  • Excellent resistance to overbake

  • Less interaction with pigments

  • Low conductivity

  • Good flow and leveling
