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.

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.

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.
