Reactivity and cure time
Product reacts to a stiff paste in 30-60 seconds. Material then slowly polymerizes to a sandable solid in 1-2 hours and cures hard in 16-24 hours. Accelerant can be added for more rapid cure times
Mix in disposable containers. Use putty knife or trowel to apply.
Clean equipment with Toluene, Xylene, oxygenated or chlorinated solvents. Fully cured equipment may require Methylene Chloride or M-Pyrol based paint stripper for cleaning.
Standard color is natural amber-tan. Custom colors are available.
The accelerant additive may be added to the Mining Putty or the ORMPS at the rate of 2-5 drops per pint of mixed product. The number of drops is measured by the number of drops off of a 3/8â€ to 7/16â€ wide flat blade screwdriver that has been dipped into the bottle of accelerant. This will speed up the product cure from mix up to tack free and sandable to about 30 minutes. To adjust this time, add or subtract drops of the accelerant.
