      LOCATION: HomeProduct CenterSeries adhesives used in optical technology and productAdhesive for rigid blocking
Name:Adhesive for rigid blocking
Technical parameters:
       They are heat-melted adhesives and can be
 melted at low temperature. They are featured
for quick hardening, easy removing and good 
bonding. They are mainly used for positioning 
bonding of ceramic, crystal, lens and prism 
during cutting, fine grinding and polishing of 
these materials. They are provided in long 
block, easy for use and very efficient.

Usage and precautions
 
(1)   Heat the mould on the electric hot plate to 70℃ – 80℃ , apply the glue on the mould evenly and place the optics on the mould in right position. When the mould cools down to room temperature, it is ready for processing.
(2)   After processing, heat the mould on the electric hot plate to 70℃ – 80℃, remove the optics and clean off the bonding layer with cloth before the mould cools down.
(3)   Clean the optics with gasoline or PGX-01 or PGX-01F to remove the remaining glue on the part surface.
