ALWA HT RESIN
ALWA HT RESIN
ALWA HT RESIN is an isocyanate and epoxy-based resin that reacts with a catalyst, suitable for fiber-reinforced materials, prepreg, and reaction compounds. It is particularly beneficial for industries such as aerospace, automotive, and electronics.
Product Variants:
1. ALWA HT RESIN M100 with viscosity approx. 50 mPa s
2. ALWA HT RESIN M2200 with viscosity approx. 2200 mPa s
These can be mixed for flexible viscosity adjustment.
Catalysts:
Two catalysts are available for varying curing rates, which can be mixed to adjust pot life. Curing occurs at room temperature, forming a brittle intermediate state that leads to a highly cross-linked duroplast after tempering up to 180 °C.
Properties:
- High glass transition and distortion temperatures
- Low thermal expansion
- Good chemical resistance
- Stable electronic insulation properties
- Nearly temperature-independent mechanical and electronic characteristics
Processing:
Compatible with fillers like quartz powder, microdol, and short-glass fibers. Fillers must be dried before use. Suitable mould materials include polyethylene, polypropylene, aluminium, and steel.
Shelf Life and Storage:
Store between 18 °C and 25 °C, avoiding moisture. Shelf life is approximately 6 months.
Technical Data at Room Temperature:
- Glass transition temperature (TG): > 280 °C
- Dielectric strength: 20KV/mm
- Long-term heat resistance: Heat class H (IEC 216)
- Coefficient of thermal expansion: approx. 65*10-6 K-1
- E-module: approx. 3500 N/mm²
- Bending strength: approx. 125 N/mm²
- Impact strength: approx. 15 kJ/m²
- Heat distortion temperature: approx. 200 °C
- Colour: Yellow to brown
Catalog excerpts
PRODUCT ANNOUNCEMENT: HIGH TEMPERATURE RESIN ALWA HT RESIN ALWA HT RESIN is a resin-based on isocyanate and epoxy (EP), which reacts after adding a catalyst. ALWA HT RESIN offers a range of possibilities for producers of fibre-reinforced materials (e.g., glass fibre, kevlar and carbon), semi-finished and finished goods. The system is also suitable for prepreg and reaction compounds. ALWA HT RESIN is particularly interesting for the aerospace and aircraft industry as well for the rail transport, automotive and electronics industry. The application area of “epic” resins are electro casting resins, lamination and injection technology (RTM procedure), vacuum infusion, casting and ramming compounds, impregnation resin, casting and injection moulding process as well as prepreg technologies, among others. ALWA HT RESIN is offered in two versions. 1) ALWA HT RESIN M100 with approx. 50 mPa s 2) ALWA HT RESIN M2200 with approx. 2200 mPa

The resins can be mixed with one another which enables a flexible adjustment of the viscosity. In addition, two catalysts are available: one catalyst with a fast and one with a low curing rate. These can also be mixed together which allows a flexible adjustment of the pot life. After adding the catalyst, the material cures at room temperature. In that intermediate B-condition the material is very brittle. Three-dimensional networks are formed, which are characterized by a high density. That tri-merisation is the prerequisite for the final mechanical values and consistencies. The tempering should...
