ALWAYS WEAR PROTECTIVE GLOVES AND SAFETY GLASSES. ALWAYS WORK IN A WELL-VENTILATED AREA. Please heed all labeled warning and caution notices on all products.
DESCRIPTION:
KBS Hi-Temp is a high temperature/heat resistant coating formulated specifically to protect metal surfaces operating at temperatures from 260°C to 812°C. With proper preparation, KBS Hi-Temp provides outstanding adhesion, film integrity, corrosion, weathering and thermal shock-resistance throughout this entire temperature range, and is guaranteed not to burn off!
SURFACE PREPARATION:
To ensure optimum long-term coating system performance, steel surfaces must be dry and free from dirt, oils, rust, and other contaminants.
The ideal surface preparation is abrasive sand blasting which ultimately leaves the desired anchor pattern for proper adhesion. Using glass beads or non-abrasive medias is not recommended as these medias tend to leave the surface too smooth for proper adhesion.
After blasting, use compressed air to blow off any residual blast media. Be sure to wear surgical-type gloves when handling to keep natural body oils off the prepared surface.
If not sandblasting, prepare surface by using stainless steel or nylon wire wheel, wire brushing, or abrasive sanding using 60-80 grit paper. This method will provide a surface equivalent to that provided by sandblasting and allow the desired surface profile (anchor pattern).
A thorough wipe down with Acetone or Lacquer Thinners is recommended to wash away residual oils. Allow surface to thoroughly dry before proceeding.
MIXING:
Do not open containers until ready to use. Re-disperse any settled-out pigments by stirring with a paint paddle to a uniform consistency. Keep lid on container when not in use.
Application Guidelines:
1. To ensure optimum long term coating system performance, surfaces must be clean, dry and free from dirt, oil grease, salts, welding flux, oxides, old paint or other foreign matter.
2. Prepare surface by sand blasting, power washing, vapor degreasing, solvent cleaning or other chemical and mechanical methods.
3. Surface cleaning methods recommended will depend upon type of foreign matter to be removed and condition of substrate. Contact KBS Technical Support for specific recommendations.
APPLICATION:
KBS Hi-Temp may also be applied by conventional or HVLP spray, airless spray, brush or roller. Do not apply Hi-Temp in heavier films than specified since blistering may occur. For maximum corrosion protection, metal surfaces should be primed with KBS Hi-Temp Zinc Primer our silicone zinc dust heat and corrosion resistant primer (25um), then topcoated with one coat (25um) of the Hi-Temp color of your choice.
If not using KBS HI-TEMP Zinc Primer, apply two coats (25um each) of KBS HI-TEMP Seal allowing at least 8 hours between coats and allow the second coat to dry at least 8 hrs before subjecting surface to any heat.
The number of coats of KBS Hi-Temp needed depends upon service conditions of equipment.
BRUSH APPLICATION:
FOR BEST RESULTS, use natural bristle or foam/sponge brushes. Apply full covering coats (35-50um). Do not flood surface with coating. Brush out thoroughly, maintaining a continuous wet edge and uniform appearing paint film. Do not over work brushing while attempting to eliminate brush marks. Whatever brush marks don’t flow out during air dry process will flow out during initial heat curing. Do however avoid runs or drips.
Allow first coat to air dry at least 8 hrs before applying recommended second coat. Allow second coat to cure at least 8 hrs before subjecting to heat curing.
THINNING:
KBS Hi-Temp can be thinned up to 5% (20 parts paint/1 part thinner). Only thin using KBS #1 Thinner. Note: Use of other thinners not approved by KBS may hinder product performance and void product guarantee.
DRY TIME:
21°C 50% RH. KBS Hi-Temp will air dry tack and thumb print free within 1/2-1 hour. Allow at least 8 hours dry time between coats. Allow at least 8 hour solvent flash off period before heat curing or placing into service.
Optimum film properties require a heat cure of 176°C for 20 minutes. Equipment such as exhaust manifolds & headers protected with the KBS Hi-Temp in the air-dried state will heat cure when placed into service.
CLEAN UP:
Thoroughly flush spray equipment and hoses immediately after use with KBS #1 Thinner or lacquer thinner. Dismantle spray equipment and clean parts, brushes or rollers.
STORAGE:
Store in a cool, dry place with temperatures between 10°C and 38°C. Keep container closed when not in use.
