• One-part, ready-to-use, heat curing silicone
• Thixotropic
• High flexibility (low-stress-adhesive) for FIPG bonding
• Primerless adhesion to many substrates

SEMICOSIL 987 GR is a non-slump, thermally curable, addition curing, one-part silicone elastomer which can be used as sealing adhesive.

SEMICOSIL 987 GR can be applied as sealing adhesive for FIPG bonding of thermoplastics (Polybutylenterephthalates, Polyamides) and metals (Al, steel) for mass production processes. On suitable substrates adhesion built up is accomplished via chemical linkages to polar anchor groups of the substrate. Examples for processing concepts are given in the following.

As type of substrates, concentration and accessability of functional anchor groups may vary, it is highly recommended that customers carry out adhesion tests for in-line quality check and adhesion performance after aging before fixing processing parameters. It is customers responsibility to check fitness for the specifc application and to ensure reproducability of surface quality.

The 'Best use before end' date of each batch is shown on the product label. Storage beyond the date specified on the label does not necessarily mean that the product is no longer usable. In this case however, the properties required for the intended use must be checked for quality assurance reasons.
