Products Description
The cyclic structure has no double bonds. The cured product is not prone to yellowing, has high heat resistance, good leakage and scratch resistance, has a long application period, low curing shrinkage rate, strong hygroscopicity, and requires strict moisture prevention.
It provides high heat resistance, high transparency and light aging resistance in a low-viscosity liquid form, and is particularly suitable for scenarios such as LED packaging and outdoor electrical insulation where strict requirements are placed on color and weather resistance.

FAQ
Q1:What is the correct storage method for MHHPA?
Re: Store it in an airtight container to prevent moisture, in a cool, dry and well-ventilated environment, away from heat sources and water sources; it is recommended to store it under nitrogen protection; use up the contents as soon as possible after opening, and the remaining materials must be resealed to prevent moisture and must not be exposed to the air for a long time.
Q2:Could MHHPA be used to cure epoxy resin alone?
Re:No, it belongs to an acid anhydride type of thermosetting agent. It needs to be combined with epoxy resin. Usually, a catalyst needs to be added as well, and heating conditions are required for the cross-linking and curing process to be completed.
Q3:What are the advantages of MHHPA in carbon fiber epoxy composite materials?
Re: It has low viscosity, excellent fiber wetting effect; the curing process has gentle heat release and low internal stress, resulting in excellent dimensional stability of the products, and outstanding heat resistance and insulation properties.
Q4: Is MHHPA suitable for outdoor applications when used as a transparent weather-resistant epoxy topcoat?
Re: Yes, it is. The cycloaliphatic skeleton is resistant to ultraviolet rays, and the cured coating has good weather resistance, and it is not prone to flaking or discoloration; however, it is not suitable for long-term immersion in strong acids or alkalis.
