Why Use Acrylic Conformal Coating

Acrylic resin conformal coating currently makes up 80% of the market. There are many reasons for this. Read on to find out why and contact us with your needs and questions.

Acrylic resins (AR) are single component materials. More specifically, they are preformed acrylic polymers that are dissolved in a solvent to be applied to surfaces. Acrylics provide an excellent barrier to moisture/humidity and have good fungus resistance. Acrylics have minimal chemical resistance making it ideal for reworking and removability.

Acrylic Benefits

Acrylics can be soldered through with minimal to no odor release. Acrylics dry to the touch in 60 minutes or less and typically cure completely in 24 hours. The cure time can be sped up with a bake. Anywhere from 17 to 23 and half hours can be shaved off. (Prior written authorization is needed before we bake any assemblies.) During cure, acrylics do not shrink and give off little to no heat.

AR can be easily applied with a brush, sprayed or by dipping.  Hand brushing is most appropriate for small scale batch productions, prototypes and for anything would otherwise require extensive masking to avoid coating.  Spraying is the best technique for large batch groups.  The most accurate control of coating is achieved with spraying.  Dipping is achieved by placing the assembly into a vat of the coating.  This procedure is well suited for small batches. 

Rapid Turnaround

Diamond MT offers a rapid turnaround. Normal turn time for Acrylic Resin coatings is only 5 business days. We understand there are times when the project needs to be finished a little faster and offer expedited service. Expedited service turn time is 2 to 3 business but is offered on a first come first serve basis. » read more
