TRANSCRIPT
using technology
MTT-989 is a novel pre-impregnated fibreglass, primer and top coat resin system for pipeline and infrastructure repairs, onshore and offshore.
Consists of multiaxial “E-Glassfibre” impregnated with proprietary underwater epoxy resin formulation, which provides effective corrosion and repair to metal, concrete, and composite infrastructure.
MTT-989 is the only repair system which cures underwater and in wet environments without any loss of adhesion or mechanical properties.
KEY BENEFITS • Effective corrosion barrier and protection • Extends pipeline life (e.g. thinned-wall pipelines) • Performs in accordance with ISO24817, ASMEPCC-2, and PTS31.40.60.12 • Reduces maintenance costs • No hot work or welding required • Little or no shut down required • Designed to withstand underwater condition > 15years • Cost effective • Permanent repair
