Luan,
 
The Dynaloy 190 datasheet indicates an immersion time of 4-8 hours needed,
not 2.

Subject: [TN] Coating tripping method.

Hi Technet,
We are having a problem concern to trip coating. Details such as:
Material: Humiseal 2A64 Part A 
	     Humiseal 2A64 Part B
	     Thinner 64
	     Dynaloy Dynasolve 190 (GEL 190)
Mixer 200 gram Humiseal 2A64 Part A and 200 gram Humiseal 2A64 Part B, stir
them , after pour 75 gram Thinner 64 to this mixer.
Viscosity: 20 seconds.

Method:  Using Dynaloy Dynasolve 190 to strip coating on PWA (Immerse PWA
into Dynaloy Dynasolve 190  about 2 hours) 

We can not strip the coating layer by this method.

Would you please help us to solve this problem.

Thanks and best regards,
