Single Coat 100% Solids Tank Linings SPECIALTY POLYMER COATINGS, INC. Single Coat 100% Solids Tank Linings

Tank Linings with 100% Solids Excellent abrasion Quicker turn around (3-5 times) No VOC limitations / restrictions No solvent entrapment No inter-coat adhesion issues Higher DFT achievable

Typical uses for 100% Solids linings in storage vessels Lining of floor and walls Hydro Carbon tanks usually lined 1 –1.5m ( feet) up wall Chemical service tanks/vessels often entire internal surface Secondary containment

100%Solids Linings Petro-Chemical Sewage / Wastewater H2S Potable Water Acids / Alkyds Pulp & Paper

Surface Preparation Surface Preparation is Key!! NACE #2 / SSPC SP10 Near White Metal – typical minimum NACE #1 / SSPC SP5 White Metal Best (difficult on existing metal) 2.5mil-5mil anchor profile recommend

SSPC SP10 Near White Metal Grit Blast

Sharp welds ground smooth prior to blasting

100% Solids Excellent at covering welds and seams jeep free

Sharp angles difficult to coat / Stripe coating recommended

Stripe coating of welds

Advantages Better Chemical resistance Higher abrasion values Higher adhesion to grit-blasted steel Higher immersion temperatures Less expense / single coat application Thicker films possible (longer life) Quick curing / faster turn-around

Disadvantages Plural Component equipment can be complicated, Experienced applicators a must! Re-Coat times are shorter than solvinated Off ratio application = expensive coating removal

Variable ratio plural component equipment

Fixed Ratio Plural Component Equipment

100% Solids linings for concrete Again Surface Preparation is Key!!! Grit blasting recommended to remove any loose concrete, providing a clean new substrate to increase adhesion Bug holes need to be filled (often twice) A moisture tolerant epoxy primer best for concrete Green concrete needs to be cured for 26 days for best results

Freshly blasted concrete

Filling of bug holes

Bug holes after primer Often more bug holes are present after the primer has been applied A second application is often required for best results

Final application of 100% Solids NSF Epoxy

Special Considerations De-Humidification may be required to hold the grit blast on steel substrates Cold climates may require insulation on the tank exterior to prevent condensation Heating often required to cure out coatings in cold weather

Ensuring Longevity / Quality Choose and experienced qualified contractor Research the lining/coating choice for the environment & contents Have a NACE/SSPC qualified coating inspector present the entire job! Ensure your contractor has experience with the lining/coating for your job * If one bid is greatly lower than the rest there is a reason why!
