## Description

- Self-adhesive

Review: FOOD just cannot stick to Silicone - For the past few years I've ONLY cooked using Silicone. Using Silicone has saved me a fortune on grease-proof paper; plain flour and oils which BEFORE I always NEEDED to use to prevent food from sticking to the containers I cooked the food in. This sealant adequately glues items together without allowing food to contaminate the adhesive properties of the product and I recommend anyone who cooks as often as I, purchasing it because it will save them lots of money in years to come as it has already done for me. I bought a cheap Silicone container which after its first use came apart. This product prevented me from throwing the item away because I was able to repair it adequately. Trouble with food container manufacturers is they DOWNRIGHT REFUSE to make adequately sized containers so I have to make these myself.
Review: Excellent, long lasting. - Nice clear sealent, I bought the first tube neatly 2 years ago, to fix, and seal, a perspex splash back for the kitchen sink. This is still as good today as it was the day I installed it. The tube allowed me to apply a fine bead of sealent and wasnt as messy to use as the cartridges. I have also used it outside to fill small gaps around a south facing windows, were ants were getting in. The sealent is still usable two years on, as long as it is stored properly. I only bought a second tube because the original metal tube has been squeezed to oblivion and I have other worksurfaces that need resealing. It has stayed clear and hasn't turned milky coloured over time even it a very damp environment.
