APPLICATION
SikaPower 4508 is an adhesive/sealant. As an adhesive, it is typically used in combination with spot welding, riveting, clamping and other mechanical fastening techniques to hold parts together before curing is complete. Joining oily surfaces is possible with an amount of oil up to 3g/m2. Due to the large variety of oils, it is necessary to carry out tests on the currently used materials under the conditions prevailing at the time of production.
SikaPower 4508 can also be used for sealing applications on EC-coated materials prior to subsequent painting processes (including powder coating).
The product is intended only for experienced and professional users.
