Both structural adhesive types are used in many different applications across many different industries. It is therefore not a straight answer as to “which one is best for me”.
Sealing corner joints in window construction is a common application. Silicone is only effective in this application for a limited period. After a year (approximately), the UV degradation of the product means the seal is no longer watertight. As a result, water ingress and corrosion can occur.
MS Polymer is a long-term solution due to its UV resistance properties. With no colour diminution (even after several years), corner joints with MS Polymer are still like the day they were installed. Not only an aesthetic benefit but eliminates the need for re-work. Some customers have commented that by using MSP adhesives and sealants they have increased their products life by up to 5 years.
For damp areas…
Other common places to use MS Polymer or Silicone is in a bathroom, wet room, or kitchen. When using silicone in these areas, the surface breaks down over time due to the softness of the product. This can lead to mould taking root in the silicone. Using detergents to remove said mould only further breaks the silicone down, which can lead to discolouration.
Most MS Polymers are mould resistant and colourfast, meaning that even after several years in operation, there is no diminution in performance. The product guarantee can vary drastically dependant on your choice of adhesive. Ventilation and heat are key to ensuring a generally mould free bathroom.
For the transport industry…
Many of the same principles apply for applications in the transportation industry. Whilst sealing up can be done with silicone, to vastly improve the service life and eliminate warranty issues due to water ingress, discoloration, mould and overpaint, MS Polymer tends to be the better of the two.
Whilst silicone is a great low – cost product for sealing up, if you are looking for long term performance that is mould resistant, UV resistant and has no colour diminution amongst it’s benefits, then use MS Polymer.
Benefits of silicone…
It feels like we’ve been very biased towards MS Polymers here! So, here’s a few good things silicones can offer:
Temperature Resistance: Silicone can withstand anything between -60C to 200C.
Sealants: Although Silicones can only be subjected to relatively small mechanical loads and low surface tension, the product can move with expansion and contraction.
