Overview
TCR Engineering evaluates paint and coating systems for industrial, marine and infrastructure assets from its NABL ISO/IEC 17025:2017 accredited laboratory (NABLT0726MH18640) in Navi Mumbai. AMPP/NACE and BGas certified inspectors cover the full coating lifecycle in the field, while the laboratory runs adhesion, thickness, salt spray, cathodic disbondment and weathering tests.
Paint and coating evaluation for industrial, marine, and infrastructure coatings. Cross-cut adhesion (ASTM D3359), pull-off adhesion (ASTM D4541), coating thickness (ISO 2808, ASTM D7091), holiday detection, cathodic disbondment (ASTM G8), salt spray resistance, cyclic corrosion, abrasion resistance, UV accelerated weathering. SEM and EDS for galvanised coatings. FTIR and DSC for epoxy coatings. TGA for bituminous coatings. Evaluation of elastomeric coating performance under sour-service exposure (Shell-approved capability).
Overview
AMPP/NACE certified and BGas-certified inspectors. The capability covers field inspection through the coating lifecycle (surface preparation, primer, intermediate, topcoat, holiday detection, and post-cure DFT/WFT verification) plus laboratory evaluation of coating systems (cross-pillar reference, Materials Testing for ASTM D3359 cross-cut adhesion, ASTM D4541 pull-off, ISO 2808 / ASTM D7091 thickness, ASTM G8 cathodic disbondment, ASTM B117 salt spray).

Frequently asked questions
What field coating inspection does TCR provide?
AMPP/NACE certified and BGas certified inspectors cover the full coating lifecycle: surface preparation to SSPC-VIS 1 and ISO 8501-1, anchor profile per ASTM D4417 and ISO 8503, dust and soluble-salt contamination per ISO 8502, wet and dry film thickness, holiday detection per NACE SP0188, and field adhesion testing.
Which laboratory tests qualify a coating system?
The laboratory runs cross-cut adhesion per ASTM D3359, pull-off adhesion per ASTM D4541 and ISO 4624, film thickness per ISO 2808 and ASTM D7091, cathodic disbondment per ASTM G8 and G42, salt spray per ASTM B117, cyclic corrosion, abrasion resistance and UV accelerated weathering per ASTM D822 and D4587.
Can TCR characterise the coating material itself?
Yes. SEM and EDS examination supports galvanised coating evaluation, FTIR and DSC characterise epoxy coatings and verify cure, TGA covers bituminous coatings, and Persoz hardness supplements cure verification in the field. Elastomeric coating performance under sour-service exposure is evaluated alongside the corrosion and sour service laboratory.
