Optimus NBPC 6100

Heavy Duty Containment Roll-Down 

Product Description
NBPC 6100 is 1:1 plural component, 100% solids multifunctional novolac resin system specifically designed to protect containment holding tanks, delivery systems, containment walls, floors and equipment. 
NBPC 6100 has high resistance to acids, alkalis and salts.  This product can be used in areas where a non-sag product is required.  NBPC 6100 is highly adhesive, abrasion resistant, has high heat deflection with added structural polymer reinforcement.  Thick film heavy duty novolac lining will cure at ambient temperatures conditions to provide exceptional structural strength and corrosion protection for surfaces at elevated temperatures in severe chemical and physical environments.  It is formulated to be extremely adhesive.

Unique Characteristics:  NBPC 6100 is a unique multifunctional system capable of primary containment, high heat exposure and excellent vertical hang characteristics.
The product will cure in the presence of moisture.  The product has excellent working time and may be sprayed or rolled.  Thinning may be required for spray applications.
This product is designed as a very chemically resistant in fairly thin coat applications.  The product system can also be used with reinforcing fabric for various specialty applications as needed.

Preparation: Concrete must have a minimum 28 day cure prior to application.  Remove any curing agent, form release materials, oils, wax, moisture or any material that may effect bonding.  Clean and wash to remove contaminants and maintain pH 8.0-11.0.
*Perform a Moisture Vapor Test before making the coating application on concrete.
Clean by abrasive “brush-off” blast.  
Provide rough profile minimum 2 mils.   
Review ASTM D4259 Abrading Concrete and ASTM F1869 Measuring Moisture Vapor Emission.  Seal/repair all bug-holes, cracks and spalls, see Madison data sheets on 820, 4010 and 3020 (joints). Steel; Near white sand blast per SSPC-SP10/NACE 2.  Welds, seams, edges, etc. grind/blast smooth and provide 2 mil profile. 

Moisture Vapor Reduction:  NBPC 6100 should be applied to concrete surfaces as part of a "systems approach".  Since concrete will out-gas causing pinholes, using the CMW vapor barrier treatment for the concrete and the Optimus 7010 as the primer, pinholes are reduced. 

Primer:  To assure good substrate penetration into the substrate use a thin coat or mist coat of 
NBPC 6100 prior to regular application coats to reduce the potential of pinholing then proceed with full coat application.

Mixing:  Jiffy mixer - 650 rpm drill motor to mix product.  *This is a very thick product that is very low sag.  Use equipment that will allow proper mixing without “spinning” the mixing containers while being mixed.  Mix at sufficient speed to thoroughly combine part A and B.  Mix until a uniform blend of the two part is evident after adding part B into part A.  Do not change the proportions. Mix completely for approximately one to two minutes.   Power stir - continue agitation during the applications. Avoid mixing air into the blend.  Mix part B before use to assure pigment is in suspension.  Mix at 1:1 ratio.

Applications: Application range - 35°F to 125°F (air and surface) and 5°F above dew point.  Apply mixed 6100-PC over properly prepared surface.
Roller/brush; product should be applied using a short nap roller, about 3/8  inch synthetic nap or short hair natural bristle.
Airless; Graco or equal.  Pump ration 30:1 or higher, 206-718 gun with fluid tip of .019 or larger orifice size with a Reverse-A-Clean tip, 3/8 I.D. or larger high pressure solvent resistant fluid line, ½ inch I.D. or larger air supply line.  Continuous air source capable of 80 to 100 psi inbound pressure at pump.
Conventional spray;  Binks or equal.  Pressure material pot with mechanical agitator, dual regulators, air gauges, oil and moisture separators.  No. 18 gun (external mix), 67 fluid nozzle, 65 fluid needle, 67 PB air cap, heavy duty fluid spring, Teflon fluid packing, ½ inch I.D. or larger high solvent resistant fluid line and 3/8 inch I.D. or larger air supply line.  Continuous air source capable of 20 cfm or more at 80 psi per nozzle and 60 psi to the pot.  Apply in an even wet coat.  Insure seams and irregularities are completely covered.  
Thinning; If thinning is required thin with MEK @ 15% or .94lbs./gal. Primer.  Check local VOC regulations prior to thinning.
Apply mixed product in even coat and insure uniform mil thickness.  Apply second coat in opposite direction to assure coverage of pin holes.  If a third coat is applied change direction again.  
Aggregate; When using a "broadcast to refusal" aggregate always use a high quality aggregate with low dust. 

Mil Thickness; Application mil thickness is predicated on the environment and potential contact to harsh chemicals, temperature and length of time of contact.
Use not less than 20 mils dry film thickness.  Depending on the application 20 mils or greater may be required, the product may be applied up to 60 mils in one coat with little or no sag or thinner. Reapply; Time between coats is 2 to 8 hours.  Cure 24 hours before opening to immersion or traffic.  Accelerate cure by using heaters or increase environmental temperature for faster cure.   Recoating/repair; If material has reached complete cure and hardness, or if subjected to extended exposure to sunlight, uniformly abrade the surface and feather the edges.  The surface must be roughen sufficiently to provide a profile adequate to insure a mechanical bond.  
Inspection;  Check for desired dry film thickness and for pinholes, holidays, bare areas, etc. before placing into operation/service.  Use 2500 volt spark detector for thick film laminates on conductive substrates.

Application Methods: Hand Lay-up Method;  Use two layers of polyester felt or glass mat or other suitable fiber reinforcement.  Adjoining layers must overlap by at least 3 inches.  Apply a heavy coat of NBPC 6100 at a rate of 30 square feet per gallon by roller or spray. Lay section of fiber reinforcement into wet coating and work in thoroughly with ribbed metal roller to fully wet the fiber reinforcement and remove air bubbles.  Minimum film thickness should be 50 mils (.050)  Apply a top coat by spray or roller to a minimum film thickness of 10 mils.  Total minimum dry film thickness for the complete laminate system is 60 mils.  Insure all seams and irregularities are completely covered.
Applicator shall wear protective clothing, goggles and NIOSH cartridge  mask.  Use positive air supply for confined spaces as required.
