Surface Treatment | Ø Use sand blasting till the level of Sa 2.5 to remove oxide skin and iron rust, roughness: 40~75 microns; Ø Be sure to get rid of the oil stain and weld spatters on the steel plate before rust removal, and burnish welding seams and closed angles; Ø For the partially rusty part, adopt local sand blasting till Sa2.5 Level for rust removal. | ||||||||||||
Temperature of base material | The temperature of base material must be over 3℃(37.4℉) above the dew point. When the temperature of base material is below 5℃(41℉), the reaction of epoxy and solidifying agent becomes slow, which is not suitable for using. | ||||||||||||
Usage | Mixing | The product is packed in two containers separately that form a unit. For use every time, completely and uniformly mix it according to the specified compounding ratio, and then leave it stationary for slaking for 30 minutes. The product must be used up within the specified mixture pot life.
