GCX Clear Polyester Spray Gel
- GCX-1
Hazardous- No reviews
GCX Clear Polyester Spray Gel is a clear, low viscosity isophthalic NPG polyester gelcoat suitable for the manufacture of composite components such as boat hulls, hatches, decks, vehicle panels, architectural and general composite mouldings. GCX Clear Polyester Spray Gel is highly UV stable and can be used clear, for cosmetic carbon fibre or decorative laminates, or pigmented to any colour.
Requires MEKP catalyst, not included. Available to buy online in 1kg, 5kg and 25kg packs.

PRODUCT OPTIONSWe won’t be beaten on price!
If you believe you’re buying an equivalent product cheaper elsewhere, contact us to discuss your requirements.
Superior quality, UV stable, clear polyester gelcoat suitable for a wide range of gelcoating operations including use as a clear gelcoat for cosmetic appearance carbon fibre and other advanced materials.
Requires MEKP Catalyst, not included.
Typical Uses
It is widely known that for high performance structural applications using carbon fibre or other advanced reinforcements (aramid, UHMWPE etc.) more advanced resin systems, such as epoxy, should be used. There are however circumstances where the structural performance of a laminate is less important, and properties such as appearance, UV stability and cost are higher priorities. In these situations, a high quality polyester gelcoat resin can be used with carbon fibre reinforcement (often just a single layer, combined with additional glass reinforcement) to produce attractive, UV stable, carbon fibre finish laminates.
For the best results, we recommend a high quality clear polyester laminating resin and extensive use of a Bristle Roller to significantly reduce air entrapment and improve the cosmetic appearance of the laminate when working with a clear isophthalic gelcoat or npg gelcoat.

- Translucent Tinting Pigment (for less vivid opaque colours)
Compatible Fillers
- Metal filler powders
- Pearlescent filler powders
- 'Glow in the dark' powders
Key Processing Information
- Ease of Use: Suitable for professional and hobby use (follow SDS advice).
- Odour: GCX Clear Polyester Spray Gel has a strong solvent odour.
- Appearance: Translucent liquid.
- Safety Precautions: Wear gloves and goggles and work in a well ventilated area. Always read the SDS before use.
- Ambient Conditions: Can be used from 15 to 30°C although pot-life and cure time will be affected significantly. An ambient temperature of 18-20°C is recommended.
- Degassing: Not needed for most applications.
- Mix Ratio: Mix in MEKP catalyst at a ratio of 1 - 3 % by weight. Use digital scales.
- Mixing: Mix thoroughly by hand for at around 2-3 minutes.
- Pot-Life: 22-28 minutes (2 % MEKP). Be sure to use your resin before this time. Further pot life details are in the TDS.
- Backing Up Time: Typically at 2% MEKP, the gelcoat can be backed up for the next resin layer after a minimum of 2 hours curing time.
- Pigments and Fillers: Pigment using polyester colour pigments or translucent tinting pigments.

The reason we can’t ship MEKP outside of the UK is because it is highly oxidizing, and standard carrier services do not permit it to be transported.
However you can purchase MEKP from any suppliers of composite materials including fibreglass (GRP) shops, roofing suppliers, boat buildings, car bodyshops etc. There is nothing special about the MEKP we supply, you can ask at your local supplier for ‘Standard reactivity MEKP’; brands such as Andanox KP9, Akperox A30, Butanox M50 (Akzo Nobel) are all suitable and widely available.
This gel can be used for infusion with polyester or vinylester resins, it is not suitable for use with epoxy infusion resin. For epoxy resin we would recommend the GC50 Epoxy Compatible Gel Coat.
Using a gelcoat spray gun such as our CG110 a smaller 2mm nozzle would probably be best. Typically with that gun, the pressure should be between 60-100 ps.
Yes, when cured in air, this polyester resin (and most polyester resins) are cure inhibited by air so any areas exposed to air will cure with a slight tacky layer. The use of a wax additive, such as our MW1 wax additive, will ensure the surface cures tack free.
