Adhesive td-870 can be used on natural rubber?
Ordinary oil seal 120~150 degrees Celsius, high temperature curing 3~10 minutes, to vulcanizing when the adhesive is not washed, sticky mold shall prevail.Valve oil seal, bearing oil seal: bottom coating at 1:13 diluted, 200-220 degrees high temperature curing for 5 minutes, cooling, painted at 1:13 diluted, 130 degrees curing 5~10 minutes, to vulcanizing when the adhesive is not washed, sticky mold shall prevail.The treated metal skeleton can be vulcanized by coating rubber.
The pen is painted, dipped and sprayed. The painted metal skeleton is dried naturally for about 1 hours and then cured at high temperature
1, before use metal surface pretreatment, metal surface to the dust, cleaning and sandblasting process.2, TD870 adhesive general dissolution, matching ratio for:TD870: anhydrous ethanol = 1:4 or 1:10TD870: butanone = 1:5 or 1:123, when dissolved, will slowly add in solvent dissolved, stirring at the same time, can be properly placed 4-5 hours to its fully dissolved.
TD870 is a kind of phenolic resin polymer powder, suitable for nitrile rubber, acrylic rubber, polyurethane rubber and metal skeleton iron, aluminum and its alloy heat vulcanization bonding. With non-toxic, high bonding strength, anti rust characteristics, suitable for rubber skeleton oil seal, adhesive mold and core, bonded bushing etc. device.
