Will fiberglass resin harden without enough hardener?
Then, will epoxy resin harden without hardener?
It is only when mixed with an epoxy hardener that they can cure properly. If applied onto a floor without the hardener, the resin would remain a near liquid indefinitely and could not transform into a durable flooring system.
Additionally, will Bondo hardener work with fiberglass resin? Once mixed, the fiberglass resin will cure in 2 hours. Directions for Use Use hardener with Bondo Fiberglass Resin. For small applications use 10 drops of hardener per ounce (2 tablespoons) of the resin. For larger applications, use half of the liquid hardener supplied, to half of the resin container.
Subsequently, one may also ask, how long does fiberglass resin take to harden?
The hardening process begins immediately, so only add catalyst to a working quantity. Once catalysed the resin gradually cures, taking on a jelly-like consistency in about 10-20 minutes before becoming hard in about 30-40 minutes at room temperature (about 20ºC). The curing process generates heat within the resin.
How long does it take for polyester resin to harden?
Adding too much color will slow down or inhibit the cure. During the curing process, the catalyzed resin goes through a series of stages from a liquid to a 'soft gel' in about 15 to 20 minutes, a 'firm gel' in 20- 30 minutes and finally to a 'click-hard' (cured) stage in 1 to 24 hours.
