Maxguard GN 0000 SC AT is a premium gelcoat from the Maxguard GN // H/S range, based on a special isophthalic/NPG resin. Maxguard GN 0000 SC AT is formulated and optimized to give finished composite parts excellent mechanical strength and long-term weathering performance, with a surface that is hard, glossy, and tough. For composite fabricators sourcing a verified spray-grade gelcoat for sanitary ware, marine, or similar high-surface-demand applications, it offers manufacturer-documented liquid and cured-resin properties that support consistent production quality.

Why Maxguard GN 0000 SC AT Resists UV and Hydrolysis
The isophthalic/NPG resin base used in the material is selected specifically for weathering resistance. Compared with general-purpose orthophthalic gelcoats, an isophthalic/NPG system offers better resistance to gloss deterioration under UV exposure and better resistance to hydrolysis in wet or marine environments. This is why the spray-grade gelcoat and the wider Maxguard GN range are positioned for sanitary ware, marine hulls and decks, and other composite products where surface appearance and durability both matter over the product’s service life.
Application and Use
it is recommended for use in the sanitary, marine, or similar industries with high demand for surface properties in composite products. As a spray-grade gelcoat, it is formulated for application by conventional or airless spray equipment, typically catalyzed with MEKP-type peroxide at the ratio referenced in the gel-time data above. As with any gelcoat, actual gel time and cure behavior will vary with ambient temperature, catalyst dosage, and film thickness, so fabricators should verify working parameters under their own shop conditions before full production runs.
Typical Industries Using this gelcoat
- Sanitary ware and bathroom fixtures (tubs, shower trays, basins)
- Marine hulls, decks, and boat building
- General FRP composite parts requiring a hard, glossy, weather-resistant surface
Sourcing Maxguard GN 0000 SC AT Through Thousands Technology
Thousands Technology supplies this grade as part of its unsaturated polyester resin and gelcoat range for overseas composite buyers, alongside catalysts and application support for FRP production. Because gelcoat performance depends heavily on verified, manufacturer-traceable specifications, working with documented data such as the figures above for this product helps marine builders, sanitary ware producers, and composite fabricators reduce the risk of surface defects, premature gloss loss, or inconsistent cure. For broader testing context, buyers can also reference ASTM Committee D20 resources on plastics testing standards at ASTM International.
Frequently Asked Questions About the material
Is Maxguard GN 0000 SC AT a brush or spray grade gelcoat?
the spray-grade gelcoat is the spray (S) grade within the Maxguard GN H/S family, with a lower viscosity than the brush (H) grade to suit spray application equipment.
What resin chemistry is it based on?
It is based on a special isophthalic/NPG unsaturated polyester resin, selected for its mechanical strength and weathering performance.
What is the gel time for Maxguard GN 0000 SC AT?
At 2% MEKP-50 catalyst, the manufacturer-published gel time is approximately 7 minutes, tested per ASTM D2471; actual working time will vary with temperature and dosage.
What industries is this gelcoat suited for?
It is recommended for the sanitary ware and marine industries, and other composite applications with a high demand for surface hardness, gloss, and weathering resistance.
Can I request a technical data sheet for this grade?
Yes, buyers can request the current technical data sheet and batch documentation directly through an inquiry to confirm specifications for a specific order.
