Restricted Chemical Substances
Effective January 1, 2007, all product supplied to the requirements of this specification must comply with the requirements of the CEMS B-50 specification.
Description of Types
Type I (Replaced By Type III)
Type I was a plastisol type sealant. It is NOT RECOMMENDED FOR NEW DESIGN. Type I has been replaced by Type III.
Type II
An extruded elastomeric adhesive that can be used for bonding roof and other panels to reinforcements over a range of gap sizes. This product is used with oily metal and must be compatible with pretreat and E-coat operations. It expands and cures in the primer oven in a temperature range of 149-177°C (300-350°F).
Type III
A pumpable elastomeric adhesive and sealant designed for bonding reinforcements to cab panels and for filling seams, gaps and holes. It shall be suitable for use in resistance-welded joints. This product is used with oily metal and must be compatible with pretreat and E-coat operations. It expands and cures in the primer oven in a temperature range of 149-177°C (300-350°F).
Type IV
Same as Type II except for reduced expansion properties suitable for joints with narrower gaps.
Type V
Similar to Type II except it is generally applied over the E-coat primer as an air/dust sealant.
Type VI
Similar to Type II except it is extruded or molded in a unique shape to improve fit/assembly and to further resist wash off.
Type VII
Similar to Type II except for its design intention as NVH (Noise and Vibration Harshness) or water/air barrier. It expands and cures in E-coat oven at a temperature range of 160-205C (320–400F).
Type VIIA
Same as Type VII except it has higher expansion properties and a lower viscosity.
Type VIII
Similar to Type II except it cures at a lower temperature.
Type IX
Similar to Type II except it cures at a lower temperature and is non-expanding.
