Although the type of surface to be bonded is important, it should be noted that one of the most critical and overriding factors in adhesion is the condition of the bonding surfaces. The presence of surface contaminants such as oils, grease, plasticizers, mold release or dirt in general can cause adhesive failure regardless of the specific adhesive. Isopropyl alcohol can be used to remove most surface contaminants. Sufficient pressure must be applied to get full contact (wet out) between the substrate and the adhesive to create the best bond. Also, seals and gaskets with adhesive should be stored in a dry, dust-free environment, and should be applied at room temperature.
Begin application by peeling off release liner one to two feet at a time. This will prevent the adhesive from contacting and picking up foreign matter. The gasket-adhesive should then be placed on the substrate firmly and uniformly one to two feet at a time. Do not stretch the seal during application. If the seal is stretched, it will pop off after a period of time. A weighted roller is suggested for uniform application pressures to avoid the subjectivity of finger pressure. Pressure must be applied during curing time.
Important to Note
Handling, application area, and surface must be clean of any contaminant such as dust, wax, dirt or grease. Application surface must be smooth.
Do not apply to any surface when temperatures are below 60F or above 85F as the adhesive may fail to perform properly.
The material should be stored in a cool dry area, 70F +/- 6F, to ensure the uniformity and performance of the product.
