  Cure Silicone exhibits superior adhesion, resists temperature extremes and UV 
  deterioration. It will not react or corrode most metals or plastics. Use on bare 
  metals, painted surfaces, glass, gel-coated surfaces, vulcanized rubber, 
  non-oily woods, polyurethane foam, PVC, and most plastic surfaces. Use it on 
  masonry, brick, concrete, stone, vinyl siding, windows and doors. It is the perfect 
  choice for general assembly manufacturing operations where superior adhesion 
  and long term performance is required. 

  When you absolutely need a silicone that sticks, choose our Project 1 100% RTV  
  Neutral Cure Silicone Adhesive/Sealant.


  Project 1 Silicone is supplied in a 10.1oz (300ml) caulking cartridge, 5 gallon pails, 
  and 55 gallon drums. Every caulking cartridge comes with one detachable nozzle.

  Warranty and Shelf Life:

  Each application should be pre-tested for suitability of this product for the 
  intended use. When stored in the original, unopened container at temperatures 
  less than 90 degrees F (32 degrees C), our Silicones are guaranteed for one year 
  from date of purchase.


  Important note: Paint will not adhere to silicone sealant but silicone sealant will 
  adhere to most painted surfaces. Always paint first and then seal. Make sure the 
  paint has had time to dry completely before applying silicone sealant.

    Great product

    This silicone adheres to anything. We've used it on ICF, concrete, & sheet metal as well as other standard materials. Also had great customer service.

    Great adhesion to silicon roof coating

    Great quality for the price. Would have given 5 stars but the color (white) is semi transparent instead of a solid white which made it hard to see while sealing cracks.

    Aluminum silicone

    Product was fine but color was a bit to light and the texture was much to shiny, almost like aluminum foil. Not suited for my purposes. If it were paintable I would probably have kept it. Please send return address barcode.

    Great for sealing Truscore Panels

    I ordered a box of this silicone and have been very happy with it. The screw in nozzle has been perfect and I can transfer a nozzle from one tube to another to use every last bit of caulk and maintain a consistent bead size. I used these with a powered caulk gun to seal Truscore PVC wall and ceiling panels and it all worked great. Next step is to order another case and seal all my windows.
