Silicone rubber is used across many industries
for many different applications – including in the design of o-rings, gaskets, cookware, ovenware,
medical devices, and prosthetics. It can, however, be difficult to bond. TECHSiL’s RTV10533 silicone adhesive is up to the task. Here we find out why
T
here are a multitude of different types of rubber compounds available, with some being much harder to bond than others.
Silicone rubber is one of those considered difficult to bond, mainly due to its high temperature resistance. TECHSiL, however, is well versed in all technical silicone applications, from using the chemistry for potting, encapsulation, sealing, bonding and moulding. One solution available from TECHSiL is
RTV10533 silicone adhesive, which has a very high strength bond over a wide temperature range. Suitable for multiple uses, it is capable of bonding a vast range of substrates. It is also FDA compliant and clear in colour, providing an aesthetically pleasing bond. Flowable and one part, this grade is very easy to work with and apply – it is air curable with a tack free time of just ten minutes. So let’s look at a couple of applications where RTV10533 met application demands.
ApplicAtion 1:
Based in the Midlands, a manufacturer of bespoke rubber products – including hoses, couplings, rubber sheeting and matting, gaskets, mouldings, extrusions and safetywear – contacted TECHSiL when it needed a strong adhesive to bond ply sheets of Fabreeka rubber together to make anti shock and vibration bases for heavy machine tools. To suit application demands, RTV10533 was
selected and tested. According to the customer: ‘The RTV10533 held the Fabreeka rubber very solidly. We are keen to try this on a number of other kinds of rubber products we fabricate’.
ApplicAtion 2:
A specialist in the manufacture of rubber products such as mouldings, gaskets, extrusions and hoses, contacted TECHSiL looking for a versatile strong rubber bonder. The company wanted to use this across its
product ranges to cut down on the number of different adhesives on its inventory list. Working with industries including food and pharmaceutical, FDA approval was required. RTV10533 is typically used for bonding
mouldings and gaskets, whilst also bonding with many different substrates such as metals, glass and ceramics, making it very versatile. After successful trials, RTV10533 is now used for the majority of the customers’ applications. Customer feedback stated: ‘This compound
is of high strength and versatile, bonding with a variety of different substrates. It has become our go-to adhesive for mouldings and gaskets. Why stock several different kinds of adhesive when one will cope well with the majority of applications. It is especially useful to our business as the compound is FDA Compliant and we do a lot of work for the food and drink processing industry’.
SucceSSful bonding
Commenting on RTV10533 silicone adhesive, TECHSiL’s technical sales manager said: “We receive a lot of praise for RTV10533, principally due to its high bonding strength. From the feedback we received we decided to share this showcase with other potential customers. “The one part silicone adhesive is used in a
multitude of applications. It has been successful on many substrates including most rubbers and textiles and is particularly good in bonding silicone coated fabric. It can be used with a primer but most customers say it will stick directly to clean bare surfaces.” For more information on RTV10533 or for help
