POLYCOR® 944 BASE WHITE
Polycor® 944 Base White isophthalic gel coats are high quality coatings developed for the fiberglass industry. These gel coats provide quality finishes, which deliver good chemical/water resistance, gloss retention, weatherability, and resiliency. These gel coats are formulated to meet the rigid requirements of transportation, boating, and sanitary applications. They have enabled customers to meet and surpass all requirements of the American national standard for plastic bath tubs, shower receptors and shower stalls, ANSI Z124.1, .2 -1995, sec. 6.1.1. 944 gel coats are ready to use, easy to spray, sag resistant, fast curing and require only the addition of the proper amount of an appropriate methyl ethyl ketone peroxide to cure. Polycor® 944 isophthalic gel coats are available in a wide range of eye-appealing colors. Customer color matching is available on request. See polynt’s 944-W-005 data sheet for standard White isophthalic gel coat.

It is recommended that gel time be checked in the customer's plant because age, temperature, humidity and catalyst will produce varied gel times. All data referencing gel or cure refers specifically to Arkema Luperox® DDM-9 catalyst. United Initiators Norox® MEKP-9 and Norox® MEKP-9H, Akzo Nobel CADOX L-50a and CADOX D-50 are expected to yield similar performance. Arkema Luperox® DHD-9, Norox® MEKP-925 and Norox® MEKP-925H, and Pergan HP-90 may yield slightly shorter gel and cure times.; The catalyst level should not exceed 3.0% or fall below 1.2% for proper cure. Recommended range is 1.2% to 3.0% with 1.8% at 77°F being ideal. Normally, the gel coat film is ready for lamination in 45 to 60 minutes. This time element is dependent on material temperature, room temperature, humidity, air movement, and catalyst concentration. Special fast cure versions are available but must be requested. These products offer lay-up times of 30 minutes or less depending on gel times. Fast cure products have shorter stability and should not be inventoried over 45 days.; These products (standard or fast-cure) should not be used when temperature conditions are below 60°F, as curing may be adversely affected.

Uncatalyzed, standard cure gel coats have a shelf life of 120 days from date of manufacture when stored at 73°F or below, in a closed, factory sealed, opaque container, and out of direct sunlight. Fast cure gel coats (gel times less than 9.0 minutes) are stable for 60 days. The shelf life is cut in half for every 20°F over 73°F. Totes of product can have even shorter shelf life (66.0% of that for drums).
