This Polyester Laminating Resin is used, among other things, in combination with CSM glass mat. The Wet-Out is very good. The resin does not sink out of the fiber. Air bubbles are easy to remove.
The resin turns from light blue to colorless when you add hardener. This way you cannot be mistaken and accidentally laminate with a non-mixed resin.
For the deeper layers, you can use the woven fiberglass mats.
We indicate for each glass mat what you approximately need in resin. This is a guideline, but of course it can vary greatly from project to project.
This Polyester is a perfect all round laminating resin and also very suitable for ponds. For swimming pools, however, we recommend a polyester resin that is more resistant to chlorine, such as the Polyester Laminating Resin Premium.
Polyester cures by adding a peroxide as a hardener. At lower ambient temperatures, more must be used than at higher ambient temperatures. Foor 100 grams of polyester you can use the below schedule:
At 2-18oC: 2,5 gram hardener on 100 grams polyester
At 18-23oC: 2 gram hardener on 100 grams polyester
At 23-30oC: 1,5 gram hardener on 100 grams polyester
At >30oC: 1 gram hardener on 100 grams polyester
The above depends very much on the amount of polyester to be produced at a time. Larger amounts generate a lot of heat by themselves and can therefore be mixed with less harder.
If the temperature is too low, curing takes a long time and sometimes it may not even completely finish. If the temperature is too high (also by using too much harder), there is a high probability of shrinkage and stresses in the cured resin.
Curing of polyester resins works well at room temperature. It is true that the post-baking of the resin at higher temperatures, as indicated by the manufacturer, often gives a stronger end result. However, in many cases this is not possible or very difficult to do.
For very small amounts we advise to use a pipet for the catalyst.

The liquid polyester has a shelf life of at least 3 months when packed in airtight packaging at a temperature of 15 to 25oC and out of direct sunlight.
Normal chemical safety requirements apply when using polyester resin and peroxide hardeners.
Do not drink, eat and smoke during processing. Wash hands after use. Avoid contact with eyes and skin. Do not ingest. Work in a well-ventilated area. If this is not possible, use a mask with an organic vapor filter.
Keep out of reach of children and avoid contact with sparks and open flame.
Always work with the correct safety materials:
liquid-tight gloves, splash goggles and mouth mask with filter. Work even with liquid-tight coverall when working with big amounts of material and always in a ventilated environment.
