PU-203 adhesive

Polyurethane adhesive operation instructions for the Model PU-2031,Range of application of products This product is aluminium special-purpose binder of honeycomb board, can also be used in foamed plastics, metal material (the iron, aluminium, stainless steel), concrete, timber, hard PVC plastics, pottery, hard bubble material,etc. and stick arbitrarily alternately. Have sticking to be intensity high, strip intensity to be fine able to bear high low temperature, ageing-resistant, construction advantage such as being convenienting. 2,Operation instructions (1) Keep the surface of the object clean. NO greasy dirt, float dust, rusty spot and moisture content(IMPORTANT) (2) The ratio of mixing is 5:1, i.e. A component: B component (wt.) is 5:1 (can use a container to measure ) . Stiring with waxing scraper until the adhesive become even light brown and ropy. Then, using the waxing scraper (tooth depth is 2mm and dentate line is 2mm) to paint the adhesive on one object. The coating amount is controlled in 350g / m2 (3) Putting another object on the above mentioned object and pressing it with pressing-in machine.Ensuring the object to be in good contact with the adhesive.(pressure is 0.5kg/cm2) (4) Can not remove the pressing-in machine until the adhesive become solidify. 3,Solidify time (1) The adhesive can be solidified within 15min - 8 hours depending on customer's requirement, and must press the object with pressing-in machine during the 1/4 of solidify time. Otherwise, it will affect the sticking intensity (If customer require the adhesive to solidify within 1 hour, the customers must finish all action from coating to pressing with pressing-in machine within 15 minutes ). (2) If customers use hot press, the temperature is 80 °C ± 20 °C, the curing time was 15min . 4,Cautions (1) This product can be used to sealing , also can avoid the shrink due to solvent volatilize. (2) Must be used up in 15min after mixing the component A and component B.
