- Application Details
DEHESIVE® PSA 847 M is a general purpose Silicone PSA for tight adhesion level. In combination with DEHESIVE® PSA 765 KR or DEHESIVE® PSA 846 L or DEHESIVE® PSA 845 T, the adhesion force can be adjusted to higher levels.. DEHESIVE® PSA 847 M is a thermal-curing system that cures at a web temperature of 90 - 200°C. The cure speed depends on formulation (e.g. the amount of Pt-catalyst, type of substrate, setting temperature and effectiveness of the oven). DEHESIVE® PSA 847 M can be diluted in solvent such as toluene or mixture of toluene/ethyl acetate or toluene/MEK. The addition of ~1% (w/w) Catalyst PT 5 is required for DEHESIVE® PSA 847 M. Adhesion promoter can be added to the formulation in case of anchorage performance has to be improved. Care must be taken to ensure the absence of catalyst poisons in the system. Common poisons are organotin compounds, sulfur compounds (a common source are rolls that have been vulcanized with sulfur), amines, acid amides, zinc stearate and phosphates. The quality of the coating compound can be ensured by using clean vessels of stainless steel, enamel, plastic or glass to prepare the batch. Batches of coating compound must be prepared in the order given below.
