Review: NO MORE LEAKY FISH TANK! - Perfect thickness (dust do wish they had a 1/312” option). Had to make a custom gasket for my Reef tanks that would constantly drip from one of the bulkhead seals, tri,,e s a pice of the suite (food grade silicon 1/16” yjickness). And for the first time in 3 years the drip is gone. Was so happy that it worked so well that I changed all of the bulkhead seals to this, cuts easy, shushes just enough to seal the pressure in the saltwater. I wish I would have found this years ago!
Review: Happy customer. - Excellent product, exactly what I needed. I purchased this to prevent my tv stand from sliding around on the tv cabinet it was sitting on. (Problem solved!). I imagine this silicon mat has many uses for a myriad of issues.

## Questions & Answers

**Q: What temperature can MATNIKS silicone actually take?**
A: A continuous working range of -100°F to 400°F. It stays flexible in freezer and outdoor cold, and holds its shape and seal near ovens, exhaust runs and engine bays where standard rubber hardens or softens.

**Q: Can I use this around food?**
A: Choose the white food grade sheet for kitchen and food preparation work on mats, liners, lids and covers. It is odourless and wipes clean. The black sheet is industrial grade and is not intended for food contact.

**Q: Which thickness should I choose, 1/16 or 1/8 inch?**
A: Take 1/16 inch when the sheet has to bend around a shape or sit in a tight gapm light gaskets, liners and shims. Take 1/8 inch when it has to carry load or hold a compression seal machine feet, anti-vibration pads and thicker gaskets.

**Q: Is this solid silicone or a foam or sponge?**
A: Solid silicone rubber at Shore A65 durometer dense all the way through, with no cells, no sponge and no fabric backing. Dimensions carry a +/- 10% tolerance.

**Q: How do I cut it cleanly?**
A: Mark your shape with a pen or chalk, then cut with workshop scissors or a sharp utility knife against a straight edge. For gaskets, trace around the part itself. No power tools needed.
