Written by: Techsil Ltd | Published:

Rubbers can be very difficult to bond especially silicone rubber which because of its excellent high temperature resistance is a popular choice for o-rings, gaskets, cookware, medical devices and prosthetics. Techsil RTV10533 provides a very high strength bond over wide temp range, is FDA compliant and bonds multiple substrates including rubbers.

There are multitude of different types of rubber compounds. Some rubbers can be very difficult to bond especially silicone rubber which because of its excellent high temperature resistance is a popular choice for o-rings, gaskets, cookware, ovenware, medical devices, and prosthetics.

Application 1 - Midlands based Willenhall Rubber & Industrial Supplies Limited manufacture a number of bespoke rubber products such as hoses, couplings, rubber sheeting and matting, gaskets, mouldings, extrusions and safetywear. At Willenhall Rubber there was a need for a strong adhesive to bond ply sheets of Fabreeka rubber together to make anti shock and vibration bases for heavy machine tools.

Application 2 - Wright Rubber Limited, are specialists in the manufacture and supply of rubber products such as rubber mouldings, gaskets, extrusions and hoses across a wide and diverse range of industries. Using FDA compliant materials Wright Rubber supply directly to the food and pharmaceutical industries in addition to general engineering, military and transport sectors. Wright Rubber were looking for a versatile strong rubber bonder to use right across their product ranges to cut down on the number of different adhesives on their inventory list.

Solution 1 - RTV10533 was selected and tested, Kevin Hadley MD of Willenhall Rubber said ‘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’.

Solution 2 - RTV10533 is used for bonding mouldings and gaskets. It bonds with many different substrates such as metals, glass and ceramics which makes it a very versatile bonder. Wright Rubber now use RTV10533 for the majority of their applications. In trials, Mark Crawshaw MD of Wright Rubber said ‘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.’

Techsil’s Technical Sales Manager, Steve Green said ‘We have had a lot of praise for the very high strength RTV10533 silicone adhesive. From the feedback we received we decided to share this showcase with other potential customer’s. The one part silicone adhesive is used in a multitude of applications. It has been successful on many substrates including most rubbers and textiles. It 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. It is one-part, translucent and flowable. A wide temperature range is covered from -60 to 200 degrees C. The compound is air cured and has a tack free time of 10 minutes.’
