PRODUCT DESCRIPTION
Duratec High Gloss Additive 904-001: Blend with gelcoat to create a repair coating or to improve the initial properties of the gelcoat. A 50:50 blend with gelcoat will air-cure, even at the thin edge of a repair. The repaired area can be polished to a gloss that goes all the way to the edge....prevent the ugly low gloss doughnut often seen in gelcoat repairs.
Duratec 904-001 High Gloss Additive is formulated to resist yellowing and provide a stable color even with exposure to bright sunlight.
Duratec 904-001 can be added to Tooling Gelcoat (15-25%) to improve air release and prevent porosity.
The High Gloss Additive can be added to any Duratec Primer to improve the gloss (for patterns and molds)

Physical Properties:
Recommended Use: Gelcoat Repair
A test blend is recommended, as every blend is unique and the Cure must be tested and assured. The cure time of the blend will vary, as every gelcoat is different. Note the cup-gel time.
Remove any cracked or damaged gelcoat. Grind out cracks down to the laminate.
Repair laminate or assure the laminate is sound.
The temperature should be at least 60F. Low temperatures extend cure times.
Sand with 180grit to a few inches outside the repair area.
Bevel the edge of the existing gelcoat.
Use repair putty (like Duratec 1810-013 Marine Fairing Putty) to fill in any low areas
Blend One: 1 part (25%) Duratec 904-001 and 3 parts (75%) gelcoat.
Catalyze with 2% 50% MEKP catalyst like Norox 925 (about 20 milliliters per quart. Note: the 1:3 blend is recommended to maximize the hide (opacity). If opacity is not an issue, use Blend Two for all the repairs.
Spray 3-4 passes over the repair, building up 12-15 mils. Allow at least two minutes between passes. Do not allow the Duratec/gelcoat blend to cure beyond the sticky/thumbprint stage between coats....usually about 30 minutes at 77F when sprayed, faster in the cup.
Blend two:
1 part Duratec 904-001 and one part gelcoat. Catalyze with 2% of a 50%MEKP catalyst like Norox925H.
Spray at least 2 passes over the repair, building up a additional 8mils or more. Be sure to get back onto the first passes while they are sticky. Cover all the previously coated area. It is possible to feather the edge of the repaired area with the second blend.
Allow to cure completely.
Sand with the finest grit that is reasonable for the surface finish. With a good finish starting with 400grit is possible.
The surface must be open for at least 8 hours between initial sanding and polishing. The open time allows for styrene release and full cure.
Sand with progressively finer grits like 400, 600, 800, 1000, Compound and polish with products formulated for gelcoat like Aqua Buff 1000 and Aqua Buff 2000.
Tooling Gelcoat Upgrade: Blend 10-25% Duratec 904-001 into the tooling gelcoat to improve the flow and spraying characteristics of tooling gelcoat. Catalyze with 2%MEKP catalyst (as recommended by the gelcoat supplier)
