CARPOL® EDAP-800 is an ethylenediamine-initiated polyether polyol. The resulting material has a nominal functionality of four and a typical hydroxyl number of 800. This tetrol is polymerized with ethylene and propylene oxides and is autocatalytic due to its amine content. This polyol’s functionality makes it optimal for use in rigid foams as a crosslinking modifier. In addition, CARPOL® EDAP-800 can also be used as a curative for most C.A.S.E. applications.

ALCOTEX 975 is a chemical blend, including methanol and 2-butanol. It is a single-ingredient product primarily used as a crosslinking agent in various CASE (Coatings, Adhesives, Sealants, and Elastomers) applications.

Dynasylan® MTMO is a bifunctional organosilane possessing a reactive organic mercapto and a hydrolyzable inorganic methoxysilyl group. The dual nature of its reactivity allows Dynasylan® MTMO to bind chemically to both inorganic materials (e.g. glass, metals, fillers) and organic polymers (e.g. thermosets, thermoplastics, elastomers), thus functioning as an adhesion promoter, crosslinking agent, surface modifier or reactive reagent. Dynasylan® MTMO is a clear, colorless to light yellow liquid with a slightly mercaptan odor. It is soluble in alcohols, ketones and aliphatic or aromatic hydrocarbons.

CYMEL® 323 is a crosslinking agent that offers fast cure, humidity resistance, improved film hardness, and solvent resistance in CASE ingredients.

CYMEL® 350 Resin is a highly methylated, monomeric melamine resin recommended for use in both waterborne and solvent-borne systems. It has very good water solubility properties, which makes it easy to incorporate with excellent stability in emulsion systems, as it remains in the water phase and does not migrate to the polymer phase. Like CYMEL® 350 Resin, it is a very efficient crosslinking agent and is recommended for coil coatings and high solids systems. CYMEL® 350 Resin has a slightly slower cure response than other monomeric methylated melamine resins. This provides excellent flow and levelling characteristics and less solvent popping on cure

Dynasylan® SIVO 202 is a new multifunctional aminosilane adhesion promoter that can be used for a wide variety of applications.

CYMEL® 325 is a new type of highly methylated melamine-formaldehyde resin which does not require a strong acid catalyst for fast cure response. CYMEL® 325 is reactive with hydroxyl-, amide-, and carboxyl-group-containing polymers. The weight loss of CYMEL® 325 during the baking process is significantly less than that of partially methylated melamine-formaldehyde resins. The baking volatiles from CYMEL® 325 contain very low levels of formaldehyde. The lower weight loss of CYMEL® 325 crosslinked coatings also results in less tendency to blister at higher film thickness. CYMEL® 325 requires only weak acid catalysis for cure; a low acid number in the backbone resin is sufficient. The cure reaction additionally can be catalyzed with weak organic acids or inorganic acids such as maleic, citric, phosphoric, or alkyl phosphoric acids, low levels of p-toluene sulfonic acid, or CYCAT® 14040 catalyst. CYMEL® 325 will self-condense, like a partially methylated resin. Higher film hardness may, therefore, be obtained by raising the level of amino crosslinking agent. The high reaction rate of CYMEL® 325 at lower temperature reduces the chance of evaporation of low molecular weight resin components. CYMEL® 325 should, therefore, be very suitable for applications where "smoking" of the baking exhaust is a problem. Compared to partially methylated melamine-formaldehyde resins, CYMEL® 325 has shown, in some water-reducible coatings, improved humidity and salt-spray resistance. CYMEL® 325 resin is FDA approved under section 121.2514 and 121.2526.

CYMEL® 1168 Resin is a highly monomeric, methylated/iso-butylated melamine crosslinker with a high degree of alkylation. Its high monomer content allows for the formulation of high solids coatings with excellent appearance, recoat adhesion, and flexibility. CYMEL® 1168 Resin is especially recommended for automotive topcoats, general metal finishes, and coil coatings. While CYMEL® 1168 Resin is insoluble in water, it shows excellent compatibility with water-soluble backbone polymers and provides very good stability in amine-stabilized waterborne formulations.

CYMEL® 385 Resin is a methylated high imino melamine resin with a low degree of alkylation. Being supplied in water, it is recommended as a crosslinking agent for hydroxyl-containing emulsion polymers and other aqueous systems containing hydroxyl or amide functionality. CYMEL® 385 Resin has a high tendency to self-condense and may be used to increase the hardness and resistance properties of thermoplastic waterborne polymers.

CYMEL® U-1054 resin is a partially n-butylated urea crosslinking agent supplied in a mixture of n-butanol and ethanol. CYMEL® U-1054 resin is suitable for industrial heat cured primer formulations because of the excellent adhesion, water and corrosion resistance properties. In can coating formulations, CYMEL® U-1054 provides an excellent balance between adhesion and film flexibility, especially after several cure cycles.

RHOPLEX® PR-409AF is an aqueous, all-acrylic binder designed for premium performance in universal stain blocking primers and primer-less paints. It’s distinct molecular weight distribution, combined with ambient crosslinking enables excellent adhesion to a variety of substrates without the use of APEO surfactants1. Coatings based on RHOPLEX® PR-409AF provide robust adhesion to metals, wood, masonry, cementitious, ceramic, alkyd and especially aged chalky substrates. The great compatibility of RHOPLEX® PR-409AF with zinc oxide can further enhance the exceptional stain blocking (household and tannin) and efflorescence of primers made with it. This binder further affords step out performance with the unusual combination of superior crack resistance combined with excellent dirt pick up resistance.

CYMEL® U-227-8 Resin is a general-purpose n-butylated urea resin that combines fast curing speed with excellent enamel stability in pigmented systems. It is compatible with low and medium molecular weight epoxy resins and is recommended for use in epoxy/urea metal primers, metal decorating, and drum and dipping enamels. CYMEL® U-227-8 Resin is also recommended as a pigment grinding vehicle. It is supplied in a mixture of n-butanol and xylene.

CYMEL® U-216-10LF resin is an n-butylated urea resin which has excellent compatibility with hydrophobic resins, including epoxies. It is the HAPS-free version of CYMEL®® 216-8 resin with the additional benefit of lower free formaldehyde. It was designed for metal deco coatings, can coatings and coil coating primers. CYMEL® U-216-10LF resin may also be added as a leveling agent in cold-cure amine catalyzed epoxy resin systems. Approximately 3% of CYMEL® U-216-10LF on a solids basis imparts improved flow properties.

CYMEL® 370 Resin is a partially methylated melamine crosslinker supplied in iso butanol. Like other high imino resins, CYMEL® 370 Resin is fast reacting and has a high tendency to self-condense resulting in films with high film hardness, gloss, chemical resistance and exterior durability. The high reactivity, combined with high solids content makes CYMEL® 370 Resin suitable for a wide range of solventborne and waterborne industrial bake formulations.

CYMEL® NF 2000A Resin is a unique trifunctional melamine-based crosslinker containing reactive carbamate functionality supplied in n-butanol. It can be used to crosslink hydroxy- and epoxy-containing polymers to give highly durable, acid-resistant films that exhibit a favorable balance of hardness and flexibility. An important feature of CYMEL® NF 2000A Resin is that it does not contain or emit formaldehyde on cure. It can be employed as the sole crosslinker in a coating or ink formulation, or it may be used at lower levels in combination with other crosslinkers, such as amino resins or isocyanates, in order to obtain a balance of properties.
