Our Easy-Mix HT 250 is a very high temperature resistant grade of epoxy glue. Used for creating strong bonds in high heat environments, it can withstand continuous exposure to temperatures up to 200°C and short-term spikes to 250°C.
HT 250 is light grey in colour and has an extended pot life (about 2 1/2 hours for a 10ml batch at 20°C). This grade of epoxy adhesive is quite viscous and can be used on a wide range of material types (more detail below).
Supplied in a 50ml double-cartridge, Easy-Mix HT-250 uses our Helix mixing nozzles and the D50 Dispensing Gun. The two components are mixed as they travel through the nozzle so there’s no need for measuring or manual mixing.
35% Cure: 8 Hours
50% Cure: 14 Hours
100% Cured: 24 Hours
Weicon Easy-Mix HT-250 is made in Germany and will set to form a very hard epoxy compound with a hardness rating of over 90 Shore D. Once set, it can be machined.

* Except for plastics such as polyethylene, polypropylene, polyacetal, polytetrafluroethylene (PTFE) and other fluorinated hydrocarbons with naturally adhesive rejecting surfaces. Within the framework of the above types recommendations, bonding of dissimilar materials pairs (such as metals and hard plastics) is possible.

Available Sizes
Weicon Easy-Mix HT 250 is available from Associated Gaskets in 50ml double cartridge containers.
Each container is supplied with one Helix Mixing Nozzle that ensures the two parts are properly mixed by the time they reach the application surface (extra Helix Mixing Nozzles are also available from AG). Weicon Easy-Mix HT 250 cartridges are compatible with our Weicon Easy-Mix Hand Dispenser D50 as well as some other brands of dispensing equipment.
Pre-treatment of Surface
To ensure good adhesion and a long lasting bond, the surfaces being adhered to must be clean and dry (Weicon Cleaner S or Plastic Cleaner may be suitable for cleaning and degreasing these). Smooth surfaces should be roughened where possible.
Application
Weicon Easy-Mix HT 250 should be applied to just one of the surfaces being bonded. The pot life given for this adhesive is for 10ml at a room temperature of 20ºC. If larger quantities are used, the curing time will be faster due to the reaction epoxy resins have with heat. Similarly, higher ambient temperatures will shorten the cure time (a rule of thumb here is that every addition 10ºC increase above room temperature will halve working and cure times).
It is always suggested that users familiarise themselves with the correct Safety Data Sheet before using Weicon Easy-Mix HT 250.
