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

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 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 suffi- cient. 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-formalde- hyde resins, CYMEL® 325has 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.

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.

Dynasylan® VPS 4721 is a bifunctional organosilane possessing a reactive organic epoxide and hydrolyzable inorganic methoxysilyl groups. The dual nature of its reactivity allows VPS 4721 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 and/or surface modifier. Dynasylan® VPS 4721 is a colorless liquid. It is soluble in alcohols, ketones and aliphatic or aromatic hydrocarbons.

CYMEL® U-21-511 Resin is a partially n-butylated urea resin supplied in n-butanol and is the HAPs compliant version of CYMEL® U-21-510. It has excellent compatibility with epoxy resins. It is recommended in primer formulations which are to be topcoated and re-baked. Low viscosity and epoxy solution compatibility make this product an ideal modifier.

CYMEL® 3745N Resin is a highly methylated melamine crosslinker designed for use in both solvent-borne and waterborne industrial finishes. Its high functionality and low tendency to self-condense promotes excellent formulated stability and results in films with very good hardness development, flexibility, formability, and resistance properties making it suitable for a wide range of coating applications, like can and container coatings, foil coatings, automotive coatings and waterborne formulations.

ALPEX® CK 450/PAST is a polyisoprene-based binder and crosslinking agent. It is used in coatings such as anti-corrosion and chemical-resistant paints, as well as in tank coatings. Additionally, it is suitable for use in letterpress, offset, and screen printing inks. This product offers excellent chemical resistance, improved gloss, and scratch resistance, while minimizing misting during application.

CYMEL® 1133 Resin is a highly methylated, n-butylated melamine crosslinker with a high degree of alkylation. It has a higher butoxymethyl content and higher monomer content compared to CYMEL® 1130 resin. Its hydrophobic nature combined with very good film appearance properties makes CYMEL® 1133 resin suitable for automotive topcoat applications and general metal finishes requiring improved durability and resistance properties.

RHOPLEX® K-3 is an acrylic crosslinking agent.

CYMEL® 1161 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® 1161 Resin is especially recommended for automotive topcoats, general metal finishes, and coil coatings

Dynasylan® GLYMO is a bifunctional organosilane possessing a reactive organic epoxide and hydrolyzable inorganic methoxysilyl groups. The dual nature of its reactivity allows Dynasylan® GLYMO 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 and/or surface modifier. Dynasylan® GLYMO is a colorless low­viscosity liquid with a slight terpentine­like odor. It is soluble in alcohols, ketones and aliphatic or aromatic hydrocarbons.

CYMEL® UI-19-I resin is a partially iso-butylated urea resin supplied in iso-butanol. The fast drying properties provide good block resistance and makes CYMEL® UI19-I resin suitable for ambient and low bake industrial wood finishes.
