Advantages

Economic Efficiency

General purpose gelcoats are more cost effective than isophthalic and other specialty gelcoats. It offers cost-effective solutions in projects that do not require high performance in indoor applications. Thanks to its low unit cost, it provides economical application even on large surface areas.

Easy Applicability

Easy application thanks to excellent flow properties and workability. It can be easily applied by spray, brush or roller. Curing times are optimized and increase production efficiency. Acts as an ideal primer for surfaces to be painted afterwards.
