Printable thermal interface gels solve automotive reliability challenge

Customers looking for high-reliability one- and two-component thermal interface gels that can be printed finally have a solution they can count on.

Customers are often faced with the challenge of using either a thermal interface material that can be printed, or one that can endure automotive reliability which includes rigorous vibration tests.

Honeywell recently launched two, new hybrid thermal hybrid products that meet the challenge of being both printable and high reliability. The first is a two-component thermal hybrid gel HLT3000, the other is one-component pre–cured HT4500 thermal hybrid gel.

Both of these products have lower viscosity and enable thinner bondlines compared with their regular hybrid thermal gels counterparts. This means that these hybrid gels can be used for printing process as well as only being able to be dispensed.

This advantage is particularly important for users that find themselves in one of the following two scenarios:

The user is using a thermal grease but finds that he cannot meet the automotive reliability because they experience pump-out or drying issues.
The user likes the reliability of hybrid thermal gels, but don’t want to invest (or do not have access to) dispensing equipment. They would prefer a printing process.

These two products were originally designed based on specific customer feedback. The HLT3000 was developed after the customer realized that he needed a two-component gel to replace grease with high reliability. Due to their initial lower-volume planned production, they didn’t want to invest in a dispensing machine. However, the final application was an automotive application for an electrical control product.

The second product, the thermal hybrid gel HT4500 was also originally designed for a customer who preferred a pre-cured gel’s reliability but also used a printing process.

Because both of the applications are automotive, it was important to have these materials tested again the automotive reliability requirements. Below are the two data packages for these materials including the rigorous vibration test results:
