We use Micro-encapsulated and Star polymer technology to produce adhesive which was used in RR series.  The micro-capsule in adhesive will break after we pressed adhesive which was coated on substrate on beneath surface. The inside substance will explore and suck on beneath surface immediately to create a vacuum capsule. That is why it can be adhered on various kind of surface. 

​

When we peel substrate off , the micro-vacuum capsule will recover immediately. That is why it can be repositionable unlimited times.
