Poligraph 140 LV Plus Premium Resin
Requires PMEC Catalyst X-8 for Catalysis.
Low-viscosity orthophthalic polyester resin, fully polymerisable, highly reactive, and thixotropic.
Technical Information
Properties
- Fast curing cycle.
- Fully compatible with pigments.
- High mechanical properties.
- Improves thermal conductivity.
Applications
- Designed as a base resin for working with fibreglass or injection resins.
- Good interlayer adhesion and very low linear and volumetric shrinkage.
- Inert mineral fillers such as calcium carbonates, calcium sulphates, dolomite, or silicas can be added. The percentage of MEKP (Methyl Ethyl Ketone Peroxide) to be added ranges between 0.75% and 1%, although it can be increased up to 2% to reduce gel time.
- The application can be manual or by machine.
- May be used in pultrusion processes.
Storage and packaging
- The product must be stored in a dry place at a temperature not exceeding 25ºC.
- Its expiry date is 4 months under these conditions.
- Generally, products will be supplied in drum format.
- For other quantities, please contact us.
