The following standards may be used in assessing what activities can be carried out after an application of PRODUCT #640.
| Temperature | 750F |
| Overcoating | 2 to 4 hours |
| Movement/Light Stress | 8 hours |
| Traffic Bearing | 16 to 24 hours |
| Immersion/Full Chemical Exposure | 5 days |
Force cures may be used to either enhance chemical resistance or to allow the coating to be placed in service before 5 days. Allow a post cure of 12 to 24 hours before force curing.
Minimum - 2 Hours @ 1500F
Minimum - 4 Hours @ 2000F
NOTE: This product will cure well at temperatures as low as 40 - 450F. However, additional curing time must be provided.
CONCRETE: Surface must be clean and sound. Remove all dirt, laitance, grease curing compounds and other foreign matter by sandblasting, mechanical abrasion. If acid etching is used follow with abrasive or mechanical abrasion. Remove water and dust from all surfaces with an oil‑free blast, or vacuum, immediately prior to application. STEEL: Prior to sand blasting remove all grease, dirt and other contaminants from the surface. Grind sharp edges to a minimum radius of 1/8 inch. Remove all weld splatters. Sandblast to a white metal finish according to SSPC-SP-5-63 or NACE standard TM-01-70 with a minimum anchor profile of 3 mils.
Mix ratio is two parts by volume base (‘A”) to one part by volume hardener (“B”).
PRODUCT #640 can be applied by brush, roller or airless spray equipment. PRODUCT #640 is designed to be spray applied at 10 to 15 mils per coat. Relative humidity during the coating process should be a maximum of 90% for application to commence.
A minimum of two coats is recommended. If the second coat is applied before the first coat cures, no surface preparation is required. Simply apply the second coat maintaining the required mils per coat. However, if the first coat has cured (when it is tack free), the first coat must be brush blasted prior to the second coat.
Clean all equipment immediately after use with MEK or acetone.
WARNING! A Component contains epoxy resin. DANGER! B Component contains alkaline amines; strong sensitizer. May cause skin sensitization or other allergic responses. Use with good ventilation, particularly if material is heated or sprayed. Prevent all contact with skin or eyes. Wear protective clothing, goggles, gloves and/or barrier creams. Keep container closed when not in use. Wash thoroughly after handling.
FIRST AID: In case of skin contact, immediately wash with soap and water. In case of eye contact, flush eyes with copious amounts of water for at least fifteen (15) minutes. Remove contaminated clothing and shoes. If irritation persists, seek medical attention. Wash clothing before reuse.
