• Unless otherwise stated, the data were determined with typical production batches using standard test methods. They are typical values only, and do not constitute a product specification.
• Coating properties, such as pencil hardness, x-cut adhesion, and impact resistance, were tested on 10-mil samples, exposed 7 days @ 23°C / 50% relative humidity.

Accelerator 3130 generally shows good compatibility with amine hardeners and should be added to the hardener component. When using this unique accelerator, there is no need to adjust the resin to hardener ratio. Therefore, it is ideal for use as a drop-in accelerator, and it allows a formulator to easily adjust an existing system for colder weather. Accelerator 3130 is effective in solvent-free and high solids coatings based on selected cycloaliphatic, polyamine, phenalkamine, and polyether urethanamine curing agents. It is also very effective in accelerating the cure of “Type-1” epoxy resin crosslinked with polyamides. Curing times are drastically reduced at 23°C and 5°C. To obtain shorter through cure, a combination of Accelerator 3130 with Accelerator 960-1 (tridimethylaminomethyl phenol) is recommended. Tertiary amine accelerators, when used as the sole accelerator, tend to increase the brittleness and reduce adhesion of the coating film. Accelerator 3130, however, has little negative effect on mechanical properties and corrosion resistance when used at recommended levels. Resistance to alcohols and acids is decreased slightly, otherwise chemical resistance is unaltered and well within what is required of coatings to protect against atmospheric corrosion. In coatings containing Accelerator 3130, surface tackiness is eliminated. In thick coatings (>5 mm) exotherms could occur at high levels of accelerator.

Accelerator 3130 should be stored in a dry place, in the sealed original container, at temperatures between 2°C and 40°C (36°F and 104°F). Under these storage conditions, the shelf life is 1 year (from date of manufacture).
At temperatures below 5°C, white crystals may develop. Mild heating (40°C) will eliminate the deposit and restore the original condition. On exposure to sunlight, a yellow or brown color can develop. These discolorations will not affect the color of coatings nor have any adverse effect on performance. Do not store in metal containers. When combined with amine hardeners, storage in metal containers is acceptable. Do not store near oxidizable materials
