Acrylic Conformal Coating

How Acrylic Protects Surfaces

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.

Why Use Acrylic Conformal Coating

Acrylic resin conformal coating currently makes up 80% of the market. There are many reasons for this

There are many benefits with using Conformal Coating. Using Printed Circuit Boards as an example, conformal coatings lower the necessity to hermetically seal a board and the board is more reliable to function properly in humid environments.

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.

Conformal coatings made of acrylic resin (AR) are very popular, because of their distinctive beneficial properties. They protect printed circuit boards (PCBs) and similar electronics from corrosion, dirt, dust, fungus, moisture, and thermal shocks. Exceptionally user-friendly, liquid AR can be simply applied by brush, dip, or manual/robotic spray, generally resulting in the fastest turnaround-time of all conformal coatings. Ease of application and rework generates low cost for both manufacturer and client. AR’s moisture protection is also very highly rated, adding to its utility for a wide range of coating uses.

  • Simple
  • Cost Effective
  • Easy Rework
  • UV Traceable
  • Easily Interchangeable

Acrylic Applications
Acrylic conformal coatings are very easily applied by standard wet methods. As one-part systems, there are similarly few obstacles to their rework or removal. Liquid methods for acrylic conformal coatings most prominently encompass brush, dip, spray or robotic techniques.AR offers superior moisture protection, conformally-coating PCBs, which can be subjected to harsh operating conditions. It generates dependable, long-term defense from environmental developments that present obstacles to appropriate functioning.
