DESCRIPTION

Features of OPTOACE
OPTOACE can be coated on PCBs with a thin film and imparts waterproof, moisture proof and corrosion protection to it. It is also easy and safe to use in a process.

Benefits of OPTOACE
– Excellent water repellency and corrosion prevention
– Saves working time by drying extremely rapidly
– Does no harm printed circuits or mounted parts
– Non-combustible
– Higher wateproofing performance than non-fluorochemical coatings
