Lucy: A little more information on your application and requirements	
		please.							
		Are you using this to encapsulate,bond,pot etc.?	
		 							
		Does the material need to be an RTV? There are many other	
		polymer systems available such as urethanes,flexible epoxies,	
		butadienes......					
									
		Is one component/room temp cure a requirement?		
									
		What are the materials you are applying this to?	
									
		Is the use of a primer an issue?			
									
		Is material cost an issue?				
									
		What are the temperature extremes for the application,is it	
		just heat(125C)?					
									
		Are there other environmental/mechanical/electrical require-	
		ments?							
									
		There are many systems available besides the ones you have 
		mentioned.Answers to the above questions and any additional	
		information would help in focusing the choices.
