Product detailed description

VEROPAL LAM AERO 45 is a clear two-component solvent-free epoxy resin with hardener for fast lamination of composite materials. Developed for the aerospace, shipbuilding and sports equipment industries. 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 can be easily colored, or partially filled. It is beautifully liquid, odorless, with a simple mixing ratio.

Usage:

• Fast lamination of composite materials - fast repairs.
• Manufacturing of composite parts in aircraft modelling, shipbuilding and sports equipment.
• Suitable for manual lamination, winding lamination, RTM/RIM/SCRMP process and infusion.
