Marine Polyester Resin
LC-1930
Premium marine resin and marine polyester resin for boat building. Pre-accelerated, pre-thixotropic marine grade resin with excellent water resistance and superior glass fiber wetting properties. The ideal resin for boats and marine applications.
Why LC-1930 is the Choice for Marine Excellence
In the demanding world of marine construction, standard resins are simply not enough. Lechi LC-1930 Marine Resin is a specialized, high-performance unsaturated polyester resin engineered specifically for the harsh environments encountered by sea vessels. Formulated with a Neopentyl Glycol (NPG) isophthalic backbone, it provides an exceptional moisture barrier that prevents osmosis and hydrolysis. Its pre-accelerated and thixotropic nature ensures it stays in place on vertical boat hulls while providing the fast fiber wet-out required for efficient boat building operations. From luxury yachts to high-speed fishing boats, LC-1930 provides the structural heart that lasts a lifetime.

Why boat builders worldwide trust the LC-1930 system
Superior Osmosis Barrier
Ultra-low water absorption technology creates a dense polymer matrix that effectively blocks water molecules, preventing hull blistering and core degradation.
Salt & UV Fortification
Includes a robust package of light stabilizers and corrosion inhibitors to protect against the combined assault of intense maritime sun and saltwater.
Precision Laminating Logic
Engineered for the hand lay-up and spray-up professional, with a viscosity profile that promotes instant fiber saturation and eliminates trapped air.
Manufacturing Process Compatibility
Our Marine Resins series is meticulously formulated to integrate seamlessly into your existing manufacturing infrastructure, from high-precision molding to heavy-duty winding.
