Isoneopentyl

What is Isoneopentyl Gel Coat?

This series of gel coats developed by Italbeit has been formulated with a resin based on isophthalic acid and neopentyl glycol and represents the highest level of chemical resistance. Isoneopentyl (Iso Npg) gel coats offer a combination of important characteristics which can be summarized as follows:
  • excellent water resistance
  • excellent resistance to UV rays
  • excellent mechanical properties
  • ease of application

Given their characteristics, isoneopentyl gel coats have been formulated to be used in the nautical sector, in the sanitary sector, tubs and swimming pools, in the manufacture of slides for water parks.
They can also be supplied in a self-releasing version, to facilitate the operations of detaching from the mould, or waxed, to improve surface drying when not working against the mould, but directly on the product.

Application features

For the application it is recommended to check the temperature of the product, the molds and the environment, which must be between 18°C ​​and 25°C. The product is supplied already accelerated and must be catalysed with the traditional MEKP at a rate of 1.5% – 2%. The thickness of the wet gel coat film must be, depending on the mold and the application method, approximately 0.4 – 0.5 mm, which is equivalent to an amount of product between approximately 600 and 800 g/m².
In the case of “airless” or similar systems, we recommend the correct setup of the system (nozzle and pressure). If further dilution should be necessary for its application, the type and quantity of thinner can vary according to the specific needs of the customer. In any case, our technicians are at your disposal for precise indications in this regard.
