What is Iso-Orto gel coat?

Gel coat series formulated with a mixture of isophthalic and orthophthalic resin to combine the high performance of the first with the greater economy of the second. The ratio between the two resins is 1:1.
The main features of this line of gel coats are:

Given their characteristics, iso ortho gel coats are used in the following sectors: good-level industrial parts, internal parts, transport, isothermal vans. They can also be supplied in a self-detaching version, to facilitate mold detachment operations, or waxed, to improve surface drying when not working against the mold 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.
