Where are the product number, batch number and manufacture date marked on the cartridge?

They are inkjet printed around the nozzle end of the cartridge

Can I add additional uncured silicone rubber to a silicone mould that is already cured?

<p>As long as the surface of the cured rubber is kept dust and grease free, more silicone rubber of the same type can be poured on top and will bond with the surface. There will be no detectable join. (unless a different coloured catalyst is used, of course) If the above is strictly adhered to then there are no time constraints.</p>

How do you increase the cure speed of a silicone?

<p><strong>1-Part Condensation Cure:</strong></p> <p>Increasing the humidity</p> <p><strong>2 Part: Silcosets:</strong></p> <p>Increase the amount of catalyst to a Maximum of 1% - Apply heat, again not more than 40C</p> <p><strong>Condensation Cure Moulding Rubbers (900 Series):</strong></p> <p>Use Cat Red 5 – see technical data sheet for more information</p> <p><strong>Addition Cure 2-Part:</strong></p> <p>Increase temperature using a curing oven – see individual data sheets. It should be noted however, that the slower the curing of silicone rubber, the better the quality and durability. You will note that any testing undertaken is done after 7 days, when the rubber has fully cured and all volatile products have evolved at which point the rubber has reached its optimum properties.</p>

How can I repair a silicone mould?

<p>Use a 1-part RTV <a href="https://acc-silicones.com/products/adhesives/silcoset-rtv-silicone-adhesive" target="_blank">silicone adhesive</a> - ensuring the edges of the tear are clean and grease free - apply as per the Technical Data Sheet. Use of a translucent adhesive will give best visual results.</p>

Which type of silicone adhesive will adhere to my substrates, will I need a silicone primer?

<p>Choosing the correct silicone adhesive for your substrate is very important. The ACC silicones guide for silicone adhesives and primers will help you select the correct type of silicone adhesive and advise if a silicone primer is needed.</p> <p>Click here for more information on <a href="https://acc-silicones.com/products/primers" target="_blank">Silicone Primer</a> or here to download the <a href="https://acc-silicones.com/download/449" target="_blank">Silicone Adhesive Adhesion Guide </a></p>

Can silicone adhesive withstand high temperature of more than 300 C ?

<p>Silicone adhesive sealants are well known for high temperature resistance. ACC Silicones range of 1-part, RTV high temperature adhesive sealants retain their flexibility and other physical properties when exposed to temperatures up to and above 300°C.</p> <p>click here to see <a href="https://acc-silicones.com/products/adhesives/high-temperature-silicone-adhesives" target="_blank">high temperature silicone adhesives</a></p>

Do you have a WRAS approved silicone grease for potable water?

<p>Yes SGM494 silicone grease is WRAS approved for hot and cold potable water.</p> <p>Click here for more information on <a href="https://acc-silicones.com/products/greases/water-potable-silicone-grease" target="_blank">Water Potable Silicone Grease </a></p> <p>Click here for the <a href="https://acc-silicones.com/download/488" target="_blank">WRAS certificate</a> </p>

Where can I find out about product disposal ?

What does RTV silicone mean?

<p>RTV is a Room Temperature Vulcanising rubber which means, it cures from a liquid into a flexible rubber at room temperature. This type of silicone chemistry is the most widely used in the formulating of silicone adhesive sealants utilising the moisture in the atmosphere to react with chemical cross linkers, thereby enabling the formation of a silicone elastomer. </p> <p>The most common systems are: Acetoxy Oxime Alkoxy or Methoxy Acetone</p> <p>Acetone cure silicones adhesives have many technical advantages they are now being specified for a wide variety of applications especially within electronics. RTV’s are extremely flexible and user friendly. It is possible to adjust the curing regime through changes to the chemistry. ACC have formulated both Acetone and Alkoxy cured accelerated cure adhesives and a thermally conductive version for use in electronics</p>

What is RTV Silicone?

<p>RTV silicone is a liquid silicone compound that cures at room temperature to form a flexible rubber. This can be either an Adhesive Sealant, Moulding Rubber or Electronic Encapsulant Potting Compound.</p> <p>The term RTV is means Room Temperature Vulcanising.</p> <p>The most common RTV silicones use a tin catalyst together with moisture from the atmosphere to cure the rubber, these are and are known as Condensation Cure.

The cure speed of Addition cure RTV’s can also be accelerated using elevated temperatures.

What is silicone rubber used for?

<p>Silicone rubber comes in a variety of forms, adhesives, sealants, moulding rubbers for reproduction, encapsulants and potting compounds for electronics and coatings.</p> <p>Silicone polymers are usually flowable liquids which are cured to form a flexible silicone elastomer or rubber. Additives provide additional characteristics such as adhesion, colour, thermal conductivity to mention a few. Silicone rubber is especially resistant to high temperatures and attack from moisture or chemicals.</p> <p>As silicone sealants they are widely used in the construction industry with excellent adhesion to glass and ceramics and plastics.</p> <p>In electronics they are used as <a href="https://acc-silicones.com/products/adhesives/neutral-cure-rtvs-adhesives" target="_blank">adhesives</a>, <a href="https://acc-silicones.com/products/encapsulants" target="_blank">encapsulants</a> and <a href="https://acc-silicones.com/products/coatings" target="_blank">coatings</a> providing high temperature resistance and being increasingly used for <a href="https://acc-silicones.com/applications/thermal-transfer" target="_blank">thermal transfer</a> in high power or heat generating applications.</p> <p><a href="https://acc-silicones.com/products/moulding_rubbers/food-grade-silicone-moulding-rubbers" target="_blank">Food grade silicones </a>for making utensils and increasing silicones mould for food products.
