DYMAX 9481 is a single part acrylated urethane conformal coating. It has
a secondary moisture cure mechanism (a bit like the cure mechanism of a
single part RTV silicone) for those areas which are in shadow to light.
The primary cure mechanism is still UV/visible light. 

Traditional UV acrylic conformal coatings had a secondary thermal cure,
so that's what makes this product new - if a secondary cure is required,
there is no need to add heat, the moisture cure just happens over time. 

There are similar products from other vendors. This type of chemistry is
a valid choice to evaluate for your coating requirements, but much
depends on board geometry, application methods, requirements of cured
material, etc. 

Regards,
Peter

Subject: [TN] NEW! DUAL-CURE(tm) 9481 ELECTRONIC CONFORMAL COATING

 Hi Technetters,

Can anyone give me some information on this new Dynmax material? Has
anyone used it? How does it compare to other UV materials that are out
on the market today? 

Thank you,
