HOT SURFACE COATING ®
APPLICATION
PREPARATION
OF SUBSTRATE :
( Methods include:
SSPC-SP 1, SP 2, SP 3, SP 6, SP 7, SP 12 )
Surfaces must be clean and dry before application. Loose or flaking old
paints or corrosion must be removed from surface before applying. Surface must
be clean of all residues and debris. Surfaces can be cleaned by power washing
with solvent wipe down, light commercial blast, or power hand tool to remove
loose flakes and debris before applying.
MIXING :
Mix with a commercial drill and a 6" diameter dispersion blade at low or medium speed for two minutes to loosen the product. Coating should appear as a thick whipped cream with no lumps once it has been blended. If it still appears to be dry, begin to add water while continuing to mix. In a 5 gallon pail, up to 1 liter of water may be added as required to achieve the desired consistancy.
APPLICATION METHODS:
HSC ® can be applied by brush, roller or spray however the preferred method is by airless spray.
- If application is by spray. use an airless sprayer that applies 2 - 3 gallons per minute (i.e. Graco 7900 @ 3,000 psi minimum with .035 - .045 tip Remove all filters) or a GRACO
Texspray RTX 1500 hopper feed texture sprayer. Use the smallest tip
that comes with the machine (2mm).
- If applied by brush use a soft bristle brush.
- If applied by roller use a 3/8 inch nap roller.
For heated applications
Apply a prime coat @ 50 mils WFT (1.25 mm) as the primer to make the initial lock down of the coating to the surface while allowing the steam to escape without causing bubbles in the coating. According to the surface heat several thin coats may need to be applied to reduce the temperature before the thicknes desired is achieved in one final application. Once steaming has stopped, apply subsequent coats at 150-200 mils per coat to build up as specified and allow to steam off between coats; allow 24 hours to fully dry before topcoating.
For ambient / cold applications
Apply HSC ® in several coats of no more than 100 wet mils or 2.5mm per coat.
Allow
1 day drying in a warm, dry environment between coats. Build up coating in a similar
manner until the proper thickness is achieved. Allow to dry in a warm, dry environment
for 2 weeks before top coating with SUPERTHERM
®. Apply RUSTGRIP
® or ENAMO
GRIP ®(solvent-based) over dry SUPERTHERM
® to toughen surface further.
COVERAGE RECOMMENDATIONS: (wet mil gauge recommended)
32 sq.ft / gal. = 50 mils WFT = 40 mils dry film thickness
17.25.0 sq.ft / gal. = 93 mils WFT = 75 mils dry film thickness
13.0 sq.ft / gal. = 125 mils WFT = 100 mils dry film thickness
10.7 sq.ft / gal. = 150 mils WFT = 120 mils dry film thickness
8.58 sq.ft / gal. = 187 mils WFT = 150 mils dry film thickness
6.5 sq.ft./gal. = 200 mils dry film thickness
5.2 sq.ft./gal. = 250 mils dry film thickness
TOPCOATING REQUIREMENTS
If a durable protective finish is required because of the surrounding environment, such as physical, mechanical abuse or over pipes subject to vibration, apply as follows. After the last coat is applied but before it dries, wrap polyester or fiberglass mesh around the pipe with the edges slightly overlapping to provide complete coverage. Allow this to dry before applying SUPERTHERM ®.
For exterior applications subjected to WEATHERING / UV Should be overcoated with ENAMO GRIP ( WB ) ® Water based aliphatic polyurethane for protection, and to improve toughness and durability. In one coat at 18 sm \ 200 sf per gallon at 8 mils WFT or 92.5 microns \ 3.22 mils DFT. Allow to dry and cure over night.
For resistance from CHEMICALS apply SUPERTHERM ® in one coat at 9 sm \ 100 sf per gallon giving 16 mils WFT or 250 microns \ 10 mils DFT to seal the HOT SURFACE COATING ® from solvent penetration which affects insulating ability. Then after the SUPERTHERM ® has cured apply ENAMO GRIP ® Solvent ( White or Coloured ) or RUSTGRIP ® in one coat at 18 sm \ 200 sf per gallon at 8 mils WFT or 92.5 microns \ 3.7 mils DFT. Allow to dry and cure over night.
For applications with HIGH HUMIDITY or SUBMERGED UNDER WATER allow the HOT SURFACE COATING ® to dry then apply SUPERTHERM ® in one coat at 9 sm \ 100 sf per gallon giving 16 mils WFT or 250 microns \ 10 mils DFT to seal the HOT SURFACE COATING ® from solvent penetration which affects insulating ability. Then after the SUPERTHERM ® has cured apply EPOXOTHERM ® in one coat at 9 sm \ 100 sf per gallon giving 16 mils WFT or 312.5 microns \ 12.5 mils DFT. The total system can be submerged under water in two days. The full cure for the EPOXOTHERM ® is 10 days but in two days it has cured enough to allow for submersion while it completes its curing cycle.
IMPORTANT:
Do not take internally. Avoid contact with eyes. If solution does come in
contact with eyes, flush immediately with water and contact a physician for medical
attention. Avoid prolonged contact with skin or breathing of spray mist. For quickest
removal from skin, wash with water before drying. KEEP OUT OF REACH OF CHILDREN.
