  THA-3000 Viton-Adhesive. Application Instructions Surface Preparation: Surface must be thoroughly cleaned. Coat a test area to make certain of good adhesion. Prepare surfaces according to these guidelines: Steel: Before sand blasting remove all traces of oil and grease using a suitable Detergent, followed by a clean water washing. All Steel surface should be sandblasted to white metal in accordance with NACE Specification # 1. Dust and sand particulate should be removed by suitable means. Aluminum: Surface must be roughed up either by sand blasting or mechanically to ensure a sufficient anchor pattern. Remove all oxidation. Dust and particulate should be removed. Wipe surface clean with Methyl Ethyl Keytone prior to application. Flexible Materials: Rubber plastics, fabric, etc., should be cleaned of surface contaminants. Belting splices must be stripped to fabric prior to application of adhesive. Concrete Surfaces: New surfaces: should have all construction dust and curing compound removed. Free of all loose contaminates. Old Surfaces: should be cleaned to remove any surface contaminants. Thermodyn highly recommends hydroblasting or sandblasting prior to application. Apply adhesive liberally to surface with brush. Bond surfaces while adhesive is still “wet” adhesive will skin over quickly, product can be re-wetted with MEK or MIBK just before bonding parts. Clamp in place for 17 to 24 hours. For large surfaces a longer drying time may be needed. Curing Material: Curing will initiate in 17-24 hours. Final curing (like FKM post-curing) can be achieved with exposure to elevated temperature. (250(F-300F() for approximately 1 hour. If possible, Step Curing is recommended. Increase temperature 50º every 30 minutes once all solvent has evaporated. Note: Rapid increase in temperature will result in blistering of coating. Coating Storage: Mixed material pot life up to 8 hours. Uncatalyzed material may be stored indefinitely. |
