Използваме дуропластична смола, която съдържа достатъчно катализатори, UV-стабилизатори и пигменти за да образува съединение което притежава нужните механични и химични своиства.

Полиестер

Ненаситнатa полиестерна смола стана в последните години най-често използвания композитен материал.НП смола е безцветен до леко жълтеникав разтвор.

Unsaturated polyester is resistant to:			Properties:
aromatic hydrocarbons			Optical: opaque
aliphatic hydrocarbons			Viscosity: low
oil			Service temperature:-30 to 200°C
acids
saline solutions
petrol
alcohols

Vinylester

Vinylester resins are produced by conversion of epoxy with methacrylic acid. The use of vinylester resins for GRP-profiles and gratings provides a high resistance to chemical attacks.

Vinylester resins are resistant to:			Properties:
aromatic hydrocarbons			Optical: yellow
aliphatic hydrocarbons			Viscosity: low
acids			Service temperature: -30 to 180°C
lyes
alcohols
grease
oil
petrol

Phenolic resin

Phenolic resins are produced by polycondensation of phenol (m-cresol) with methanal (formal-dehyde).Phenoplastics ( production )

Epoxy resin

Epoxy resins are compunds, which have one or more reactive epoxy or hydroxyl groups. As a rule they originate from bisphenol A ans epichlorhydrine by a combination of polyaddition and polycondensation with a followed curing process.

Epoxy resins are resistant to:			Properties:
aromatic hydrocarbons			Optical: opaque
aliphatic hydrocarbons			Viscosity: low
organic solvents			Service temperature: -30 to 180°C
petrol
oil
alcohols
saline solutions
acids
lyes

Acrylic resin

Acrylic resins are produced by ploymerisation of acrylic acid, methylic acid and the pertinent esters.

Acrylic resins are used in areas in which a high resistant to fire and a low smoke emission is requested. For pultrusion acrylic resins are not so common.

Acrylic resins are resistant to:			Properties:
solvents			good burnig properties
alcohols			low smoke emission
			weather proof
			optical: opaque
