Adhesion Promoter Additive
Combined with solvent-based and solvent-free addition-curing silicones a better anchorage of the silicone film on textile substrates can be obtained with WACKER® ADHESION PROMOTER HF 86. In these systems WACKER® ADHESION PROMOTER HF 86 is clearly dilutable. The standard application concentration is 0.5 - 2 wt %.
Combined with HTV silicones, a better anchorage can be obtained by priming the textile with an aqueous solution of WACKER® ADHESION PROMOTER HF 86. The standard concentration for this application is 4 wt %.
ADHESION PROMOTER HF 86 is added to liquid silicone rubber formulations and thorougly homogenized with standard mixing equipment.
The reactivity of addition curing silicone rubbers can be reduced by the addition of ADHESION PROMOTER HF 86 , and the curing times should be increased by 20-100%. Furthermore, the viscosity of liquid silicone rubber formulations can increase upon addition of ADHESION PROMOTER HF 86. It is strongly recommended to run preliminary tests to ensure a working coating process.
This product is available in 5 kg and 25 kg pails, 200 kg drums and 1000 kg IBCs.
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.
