Product detailed description

VEROPAL LAM 400 is a clear two-component solvent-free epoxy resin with a hardener for slow lamination of composite materials. It has a lower viscosity, it is self-levelling. Saturates lamination fabrics well. It has very low shrinkage when cured. Short processing time, the casting is hard. It is beautifully fluid, odorless, with a simple mixing ratio. It can be easily colored, or partially filled.

Usage:

• Fast lamination of composite materials – quick repairs
• Production of composite parts
• Suitable for manual lamination, winding lamination, RTM/RIM/SCRMP process and infusion.
