do the repairing for scratch part.
1. Surface treatment:Do the roughing treatment for the scratch part and clean it with cleaning agent.
2.Preparation:According to the mass ratio A: B=5:1 or volume ratio A: B=4:1,make the A and B two components mix uniformly,and use it up within the specified operation time limit.
3.Coating: Make the well mixing materials be coating on the pending-repair part layer by layer,the first layer should be compacted,make it infiltrate fully with
the substrates.If the next working procedure needs machining,should keep the appropriate machining allowance.
4.Curing: It can do machining after curing 8 hours at the temperature of 20-25 degree,it can be put into using after curing for 24 hours,if the temperature is low,
should heat it up or prolong curing time to promote the curing.
the repair precision can reach to the original design requirements,it can be used for many years after repairing,repairing location is in good condition.
