Our Range
Orthophthalic Gelcoat
Our orthophthalic gelcoats are manufactured using thixotropes, surfactants, pigments and accelerators to improve the durability of components. They also have the dual ability to promote a good aesthetic finish.
These gelcoats are used for non-critical work and can improve the durability of components and protect the laminate for the external environment. A gelcoat finish provides a smooth aesthetic finish, and elimiantes the need for painting.
Isophthalic Gelcoat
Isophthalic acid type base gelcoats are used to make a superior water and environmental resistant part. These gelcoats have superior blister resistance and toughness when compared to orthophathalic based gelcoats. Our Isophthalic Gelcoats also offer better gloss retention, ultraviolet (UV) stability and usually lower styrene emissions than orthophthalic gelcoats. Isophthalic Lloyds approved gelcoats are available.
We offer a range of colours, suppliers and weight of gelocats through our ecommerce site or sending us a message where one of our team will call you back.
Tooling and Vinylester Gelcoat
Our tooling gelcoats differs in that it can cure to a much harder surface than regular gelcoats types, meaning that it can be polished to a higher lustre.
Vinylester gelcoats provide maximum resistances to chemicals and solvents. Owing to its high deformation temperature, this type of gelcoats is suitable for parts when used with high peak exotherm resins or when there is a requirement for post curing. This gelcoat is ideal for when there is a necessity to reduce cracking. Corrosion resistance guides are available upon request.
NPG Gelcoat
Our NPG based gelcoats and skin coats offer better resistance to blister formation than our Isophthalic acid propylene gelcoats. They have a higher chemical and heat resistance. Suitable for all industries but most commonly used in the marine industry.
With our range of suppliers, only the best raw materials, and latest technologies are used to offer sustainability, stability and usability. All of our gelcoats can be used with our high quality polyester pigments.
Gelcoat for Moulding
According to the CCP cook Composites and Polymers Co, 2009 Composites Applications Guide, Eleventh Edition:
A conventional gelcoat is applied with spraying equipment, as brushing of gelcoats is not recommended. Proper application of gelcoat is critical to producing cosmetically appealing and durable parts. Improperly applied gelocat, increases the cost of the part. The amount of additional cost incurred depends on the number of rejected parts as well as the effort required to rework the parts. Making the investment of properly applying the gelcoat can pay big dividends by reducing rework and scrap. Proper gelcoat application includes material preparation, equipment calibration, use of trained spray operators and appropriate spray methods.
