Gelgraph

A finish that protects and performs.

+25%surface hardness versus conventional gel coat
Gelgraph

High-modulus gel coat enhanced with graphene. Superior mechanical performance, durability and resistance to environmental agents, with better adhesion and lower weight. For advanced composite applications, airless or in-mould, with marine versions.

Features
High surface hardness

Barcol > 65 (specification criterion): +25% versus conventional gel coat.

Greater mechanical strength

More hardness and impact resistance: reduces the risk of cracks and surface damage.

Lower brittleness

Its high elastic modulus absorbs stresses without breaking, preventing microcracks.

Abrasion resistance

Withstands wear from friction and continuous contact.

Superior chemical resistance

Against acids, solvents and corrosive agents.

Lower permeability

Reduces absorption of moisture and external agents.

Thermal stability

Withstands temperature changes without deforming or losing properties.

Greater adhesion

Better integration with the substrate: prevents delamination and detachment.

UV resistance

Protects against ageing and yellowing from sun exposure.

Lower shrinkage

Minimises shrinkage during cure, improving dimensional accuracy.
