Dow Corning-3145 DC Clear, 3OZ Adhesive, Clear

Clear RTV. In date. Delivered in good condition. This is a thick adhesive/sealant RTV, non-acidic, non-corrosive, suitable for use in and around electronic circuitry. It is silicone based, so it can contaminate cleaning equipment and interfere with conformal coating adhesion if used for part bonding on circuit card assemblies. Cannot be painted. Bonds nearly anything to anything else. Flexible bond won't crack. Withstands high temperatures. Great stuff. I always keep 3145 and 3140 (thin RTV coating) in the shop.

Good RTV

Product was expired and late delivery from requested date.

I used this adhesive to glue items together. Once it is dried, the bond is stronger than the super glue.

I needed a non corrosive RTV for electronic applications and 3145 was what I used before I retired from the trade.

Use this for everything outside and Inside

Although this is a superlative product, it is extremely thick and is packaged in a tube so flimsy that it's barely more than aluminum foil. The tube popped apart on first use, wasting the unused portion of the product.

The container cracked open in several places from the pressure of squeezing the silicone out during first usage. Surely for the amount this product costs, we should expect packaging that is up for the job at hand.
