Amino crosslinkers tuned for every application:

Throughout the coatings industry, amino crosslinkers are use in a variety of applications ranging from: automotive, coil, general industry to industrial wood, paper, foils and electronics. These crosslinkers, rich in amino groups, form vital bonds within coatings and are typically combined with Acrylic, Polyester, Alkyd and Epoxy resins where they can react with hydroxy-functional or epoxy functional groups. These crosslinkers can also be used in combination with other crosslinking technologies to find the right balance in performance. Our portfolio highlighted below, provides solutions for both solvent borne and waterborne coatings as well as the typical catalysts needed to initiate the reaction. Next to this we have a range of HMMM resins suited for the rubber, tire and compounding industry

Your success is our goal

allnex’ amino crosslinker product portfolios are focused around innovating solutions and creating new chemistries for your long term needs. Our approach is based on gaining a fundamental understanding of the technical and environmental challenges encountered by our customers. With this in mind our portfolios provide a wide range of technologies to match your application requirements.
 

• Curing time and temperature

• Balance of properties like gloss, hardness, chemical resistance and flexibility

• Reactive with a variety of functional sites including hydroxyl, carboxyl, amide, carbamate

• Options for high solids, lower VOC and low or no formaldehyde content or emissions

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. 

• Clear Coat – for improved acid etch resistance try CYMEL® NF 2000A or 
  SETAMINE® US-138 BB-70
• Base Coat – for levelling and flow in WB or SB formulas use CYMEL® 325 or 
  CYMEL® 327
• Primer – for better adhesion and chip resistance can employ CYMEL® 303 LF

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
