Gel Coats

Overview

The surface resins or gel coats from ebalta are essential in the production of negatives, master models, jigs or foundry patterns.
They are used, for example, in the build-up process of extensive models made of gelcoat, followed with a coupling paste and a corresponding resin rear frame. The versatile products can be used universally and are very easy to spread.

Epoxy Gel Coats

Depending on the requirements, models and moulds made of ebalta gel coats are easy to grind, polishable, resistant to chemicals and very dimensionally accurate.
ebalta offers a full range of epoxy surface resins that suit a diverse working condition including highly abrasion-resistant models and moulds, and dense or impact-resistant surfaces

PU Gel Coats

For the surface coating of foundry patterns or core boxes that use alternative materials for backfilling we can offer a select range of polyurethane based gel coats.
These are also suitable for highly abrasion-resistant models and moulds, and offer impact-resistant surfaces.
