FINDING THE RIGHT SEALANT FOR YOUR ACTIVITY

Thursday, December 10th, 2020

There are hundreds of different sealants and adhesives – that doesn’t make it easy to choose the most qualified product for your exact application, even for a professional! Three of the most used glues and sealants are silicones, painter’s or acryl sealants and MS polymers. They all have their strengths and weaknesses, but once you know them, making the right choice is much easier! Time to give you a nice and easy overview. 

Silicones
Silicones always preserve their flexibility and that’s the reason for their great sealing capacity. Their ‘binding’ capacity is less good, so you better not use this product for gluing materials.

Strengths
•Great flexibility
•Good resistance against bad weather and UV

Weaknesses
•Less binding
•Often not paintable
•Only usable on dry surfaces

Painter’s or acrylic sealants
Thanks to the dimensional stability, these sealants are ideal for walls, for example during the preparation of paintwork or the finishing of mortar in brickwork and plastering. They’re not water-resistant, so you better not use them in bathrooms and kitchens.

Strengths
•Good dimensional stability
•Easy to smoothen
•Good and fast paintability

Weaknesses
•Weak elasticity
•Not water resistant


MS Polymers
MS polymer is suited for gluing as well as for sealing. It combines the different advantages of silicones, acrylic and adhesives. In lots of situations MS polymers are the ideal product.

Strengths
•Good bondage on different materials
•Great flexibility and shock resistance
•Suitable on moist surfaces
•Great paintability
•Not harmful to the environment

Weaknesses
•Less colour consistency
•Weaker resistance against UV

Screwing or gluing?

Mounting materials can be done in two different ways. Some professionals are using screws and bolts on a daily base. Others, on the contrary, use a glue gun. But what’s the best thing to do?

There are quite a few differences between these two methods. A glue is much more flexible than a mechanical attachment. Working with adhesives means you don’t have any troubles with noise pollution, vibrations or dust. Very convenient when you are working at people’s homes. Furthermore, a glue spreads the power to the whole surface of the materials attached to each other.

A glue is often an easier product to work with, but not in every situation. When a surface is not dust free or dry, it’s prudent to use your screw-driver or drill.

Gluecom also has an assembly adhesive to offer: MX 11000 is a PU adhesive which is perfectly suitable to bond several materials (wood, metal, stone, plastic, concrete, PU foam, rockwool,…) to each other.
