TECHNICAL DATA
Optical Quality Rosin
PD8005
PD8005, PD8025

OPTICAL QUALITY ROSIN is an excellent non-crystal, ready to use, rosin obtained from pine resin. It leaves a non-volatile, transparent, brittle glassy solid ideal for blocking precision optical lenses. OPTICAL QUALITY ROSIN can be added to any natural polishing pitch to increase the hardness, tack, and friction.

Application

Depending on application, OPTICAL QUALITY ROSIN can be applied in two basic methods:

  1. Pre-melt OPTICAL QUALITY ROSIN in a controlled heating vessel, and apply or pour molten rosin to blocking plate or lap, and then mount the workpiece.
  2. Pre-heat the blocking plate or lap and work piece, and wipe the rosin across the heated tool and mount the workpiece.

Optical Quality Rosin can be removed from the parts by using Uniclear or Uniclear II. For best results, please consult with UPI technical staff to recommend optimal processing conditions.
