What is Industrial Gel Coat?
Series of gel coats based on orthophthalic resin and mineral fillers. Their peculiar composition makes them particularly suitable for applications that require subsequent sanding and/or painting or for topcoat applications on products that are not used outdoors. They can be used when no special chemical resistance requirements are required. The main features of this series of gel coats are:
- good sandability
- low linear shrinkage
- ease of application
- ease of application
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.
