Havelpol 4-UV + pure Polyester resin

Chemical Family: Polyesters

Havelpol 4-UV + pure Polyester resin is light stabilized polyester resins containing styrene and methyl methacrylate. Its use is recommended in the manufacture of maximally clear manually GRP-produced film or casting and potting art objects. Fully cured laminates made from Havelpol 4 and powder associated mat of glass fibers "E" in quality for the production of films can exhibit light transmittance of more than 80%. They exhibit excellent resistance to weathering and stable appearance even after prolonged exposure.

Properties

Physical Form: Liquid

Identification

Casting: It is a special section in which it is necessary to pay attention to its own findings regarding the dosage and temperature control. For casting procedures carefully the properties and we recommend to do any samples with various proportions of catalyst and accelerator.
