Many of the adhesives used in aerospace applications are two-component systems. The problem, however, is that weighing and mixing components together in-house often leads to weighing errors or under-mixing, contamination, time-consuming and expensive rework, and scheduling delays.
Worse yet, undiscovered problems can affect these adhesives, as well as critical hardware, in space, where repair isn’t feasible and failure is not an option.
For these reasons and more, engineers turn to Appli-Tec.
Appli-Tec specializes in the production of PMF multi-component materials including epoxy, silicone, polyurethane and polysulfide.
Meticulously processed to exact specifications, Appli-Tec’s precision mixed and frozen (PMF) adhesives guarantee consistent results. Rigorous testing ensures every batch of material performs the same.
To obtain the PMF adhesive, Appli-Tec mixes the Part A (resin) and the Part B (hardener) of an adhesive system. We then degas (or remove the air from the mixture), and freeze the material to <-40°C.
The product is shipped under dry ice to maintain the <-40°C temperature. By storing the material at less than <-40°C, the reaction is stopped for months – up to one year.
When ready to use, customers simply remove a syringe from the freezer, wait 10 – 30 minutes (depending on syringe size) for the syringe to thaw, then use. The material is as good as if it were mixed minutes prior.
When you switch to Appli-Tec PMF adhesives, you’re assured of zero mixing errors, reduced risk, and peace of mind. No other frozen adhesive supplier matches our expertise and attention to detail.
Our state of the art, highly refined, well-documented process will assure the highest quality.
