Adhesives for special requirements


Special requirements call for special solutions. The advantage of adhesive bonding is that there is the right adhesive for almost every application scenario. We show you how to choose the right adhesive in our WE explain video “Finding the right adhesive”. Another handy helper in making the decision is our Adhesive Finder. In order to give you an idea of the multi-faceted requirements adhesives have to meet, we would like to present three of your special types. In addition, there are countless other adhesives that are perfectly suited for their specific appliation area

Permanently elastic adhesive and sealant
with a fire resistance


Flex 310 M FireSeal is a permanently elastic adhesive and sealant based on SMP with a fire resistance up to 120 minutes. Tested and classified for all joint structures according to EN 1366-4. The paint-compatible sealant with very low volume shrinkage meets the highest demands in terms of fire protection, such as the requirements of the International Maritime Organisation IMO FTPC Parts 2+5 as well as for rail vehicles in accordance with DIN EN 45545-2 R22/23 HL3. The very low emissions allow safe indoor application. Flex 310 M FireSeal adheres very well even to powder-coated, painted, galvanised, anodised, chromated and hot-dip galvanised surfaces. It is suitable for use on metal, plastics, concrete and wood. The adhesive and sealant can be used in many application areas. It is suitable for fire barriers and covers, for joints in non-structural components with fire resistance requirements, for connection joints and for sealing cable ducts, pipe openings and housings.

Silicone for high-temperature sealings


If in adhesive bonds or sealings exposed to heat a silicone is required instead of a cyanoacrylate, we recommend using our Silicone HT 300. WEICON HT 300 withstands temperatures from +300°C/+572°F - whether it’s on a stove, fireplace, oven, exhaust pipe, gas heater, boiler, or chimney damper. The high-temperature-resistant special silicone is suitable for bonding and sealing compensators for ventilation systems, sealing elements made of pore silicone, hobs (gas, ceran, induction), panes in ovens or fireplaces, wear-protection plates made of aluminium oxide on steel, or inspection doors for exhaust systems.
