CARPOL® PGP-3000 is a propylene glycol-initiated polyether polyol. CARPOL® PGP-3000 has a functionality of two and an average molecular weight of 3000 Da. This diol is polymerized solely with propylene oxide for controlled reactivity.

EBECRYL® 3730-TP25 is the modified diacrylate ester of a bisphenol A based epoxy resin diluted 25% by weight with the reactive diluent tripropylene glycol diacrylate (TPGDA)(1). It is designed primarily for use in ultraviolet light (UV) or electron beam (EB) curable formulations. EBECRYL® 3730-TP25 is light in color with high UV/EB reactivity, and exhibits good wetting of pigments, matting agents and substrates compared to unmodified epoxy acrylates. Cured films based on EBECRYL® 3730-TP25 will typically demonstrate high gloss and hardness, and good chemical resistance.

EBECRYL® 3500 is a modified bisphenol A epoxy diacrylate that exhibits relatively low viscosity, outstanding performance in many wood coating applications, and adhesion to many plastics. Films of EBECRYL® 3500 cured by ultraviolet light (UV) or electron beam (EB) demonstrate good flexibility, high gloss, toughness, adhesion and superior chemical resistance.

Polycin® D-140 is a 100% solids, castor oil-based derivative designed for use as a polyol or reactive diluent in polyurethane systems. Polycin D-140, with its very low viscosity and secondary hydroxyl groups, will allow for the formulation of higher system solids with improved VOC reduction and longer pot-life. Polycin® D-140 will also impart the beneficial properties of castor oil derivatives, such as improved flow and levelling.

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® 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.

EBECRYL® 8210 is an aliphatic urethane acrylate that exhibits low viscosity and high reactivity in ultraviolet (UV) light or electron beam (EB) curable coatings. Cured films of EBECRYL® 8210 demonstrate high hardness with good scratch, abrasion and chemical resistance. EBECRYL® 8210 also contains primary hydroxyl groups that can be utilized for dual cure polymerization. Dual cure can provide instantaneous tack-free coating surfaces via UV or EB exposure while reaction of the hydroxyl groups with a suitable isocyanate enables polymerization in regions of the coating where UV or EB energy exposure is insufficient or absent.

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.

EBECRYL® 3720-TP25 is the bisphenol A epoxy diacrylate, EBECRYL 3720, diluted 25% by weight with the reactive diluent tripropylene glycol diacrylate (TPGDA) (1) to provide a lower viscosity, easier handling product. EBECRYL® 3720-TP25 exhibits light color and fast cure response. Films of EBECRYL 3720-TP25 cured via ultraviolet light (UV) or electron beam (EB) demonstrate high gloss, surface hardness, and the superior chemical resistance typical of an epoxy resin.

Polycin® M-365 is a solventless, castor oil-based derivative designed for use as a polyol or viscosity modifier in polyurethane coating systems. Polycin® M-3655 will impart higher hardness and strength, and as a reactive diluent, Polycin® M-365 provides VOC reduction along with the beneficial properties of castor oil derivatives, such as improved hydrophobicity, flow, and leveling.

WANNATE® HMP-100 is a aliphatic diisocyanate prepolymer based on polypropylene ether glycol. It is a colorless or pale yellow liquid with low viscosity and characteristic odor.
