SERVICE INFORMATION
ThreeBond sealants TB1207B, TB1104 and TB1281 are recommended for use on Isuzu vehicles. These products are widely used at the Isuzu factory during vehicle assembly. When selecting a sealant, its chemical resistance, temperature tolerance and surface applicability must be considered.
ThreeBond 1207B (TB1207B) is a quick-setting, black silicone gasket. It is resistant to engine oil and high temperatures, suitable for use on the engine head.
ThreeBond (TB1104) liquid gasket has a high viscosity which provides good coverage for rough surfaces, when scars and gaps must be filled. It may be applied to various flange surfaces and screw sections to prevent leakage of water, oil, gases and fuel. A rubber-type elastic body is formed when it dries after application, which gives good resistance to vibrations and impacts. It is recommended that TB1104 be used in conjunction with the proper gaskets, not for gasket forming alone. TB1104 is highly resistant to oil, water and gasoline, and is resilient against clamping pressure.
ThreeBond 1281 (TB1281) silicone gasket is a redbrown paste. It is not formulated for use in the engine head, but because of its high resistance to gear oil, it is recommended for use in the transmission.
Figure 1:
This Service Bulletin contains a chart (Figure 1) to use as a guideline when selecting ThreeBond sealants TB1207B, TB1104 and TB1281. An X in the chart indicates that the sealant is suitable for applying in areas with the characteristic listed. For example, TB1207B is suitable for the oil pan area, but not the water pump areas, since it is not water resistant.
