Catalysts & Initiators

General Catalyst GC-008 is a kind of indoor and outdoor general type catalyst, it is self-crosslinking, can improve the adhesion of the film, does not affect the flow and gloss, has the effect of anti-yellowing property. It can completely improve the mechanical properties of the film when cures at 160 degrees to 200 degrees. It can be used as a curing accelerator for epoxy powder coating, epoxy/polyester powder coating and pure polyester /TGIC powder coating to improve curing effect, or as an internal catalyst containing carboxyl polyester resins to reduce curing temperature or shorten curing time. In indoor and outdoor system, curing condition can achieve 160 degrees /15-20 minutes, 170 degrees /10-15 minutes, 200 degrees /3-5 minutes , flow and mechanical properties are good.GC-008 could completely replace imidazoles, diphenylimidazoline and other catalysts which are easy to get yellowing and affect the leveling and storage stability, General Catalyst GC-008 is the upgrading product of them.

CYCAT® 600A is an organic acid catalyst recommended to accelerate the crosslinking reaction of amino resins with polymers containing hydroxyl, carboxyl, or amide functionality. CYCAT® 600A is soluble in aliphatic and aromatic hydrocarbons, esters, ketones, alcohols, glycol ethers and water. It may be used as a replacement for less soluble acid catalysts, such as para-toluene sulfonic acid, in low alcohol-containing formulations. For formulation of 1K systems, CYCAT® 600A should be blocked with an appropriate amine, such as AMP (2-amino-2-methyl-1-propanol).

EBECRYL® 7100 is an acrylated amine primarily used as a hydrogen donor, or photoactivator, in ultraviolet light (UV) curable coatings and inks. When used in formulations in combination with a photosensitizer (e.g. benzophenone), EBECRYL® 7100 provides rapid UV cure response in air by mitigating the effects of oxygen inhibition at the coating or ink surface. Unlike conventional tertiary amines such as N-methyldiethanolamine, EBECRYL® 7100 reacts to become part of the UV cured polymer, resulting in lower residual odor and improved moisture resistance. EBECRYL® 7100 also promotes adhesion to plastic substrates and lowers viscosity when used as a primary component in UV adhesives and coatings.

EBECRYL® P115 is a copolymerizable amine used as a hydrogen donor, or photoactivator, in ultraviolet light (UV) curable coatings and inks. When used in formulations in combination with a photosensitizer (e.g. benzophenone), EBECRYL® P115 provides rapid UV cure response in air by mitigating the effects of oxygen inhibition at the coating or ink surface. Recommended levels are from 5 to 15% based on the total formulation, usually combined with 3-5% photosensitizer. EBECRYL® P115 can be used with EBECRYL® P39 (1) (a polymeric benzophenone derivative) to produce UV cured coatings and inks with low residual odor.

CYCAT® XK 406 N is a catalyst used in can coating and lacquer applications. It features high crosslinking and stain resistance, functioning as a catalyst in CASE ingredients.

Addocat® 118 is a catalyst for the production of PUR rigid foams.

TEDA-L33E is a chemical mixture and blend used as a catalyst in industrial additives.

Cotin® 227 is a dibutyltin diacetate, a liquid organotin catalyst recommended for the manufacture of silicone and polyurethane systems. It can be used in these primary reactions as well as secondary types such as allophanate and biuret formation.

UVACURE® 1600 is thermally stable iodonium salt photoinitiators are used to induce the polymerization of epoxides and other cationically polymerizable materials on exposure to UV light. UVACURE® 1600 is p-(octyloxyphenyl)phenyliodonium hexafluoroantimonate in solid form. It is compatible with most UV cationic cure systems and is especially useful for the rapid polymerization of thin clear coatings on metal, plastic, and paper substrates. Coatings cured using UVACURE® 1600 generally exhibit excellent adhesion, particularly on metal substrates.
