COMPRESSED POWDER MATRIX is an outstanding product for capturing every detail from your master molding plate.

• When heated it becomes soft like a paste allowing for easier and
deeper penetration of magnesium and photopolymer master plates
• Two Thicknesses:
A = .150”-.160” overall with .080” floor (best for Standard Etch)
B = .230”-.240” overall with .135” floor (best for Deep Etch)
• Little to no risk of damage to the master
• Exact reproduction of fine details into the board
• Wide time and temperature range for processing
• Virtually unlimited shelf-life without pre-curing

Processing Instructions

Because this material melts so completely before hardening, it is essential that you use bearer bars to control platen spacing and alignment.  Processing is a two-step operation.

1)  Spray a liberal amount of Spray Release Solution on the magnesium master.  Do not spray the matrix directly.
2)  Platens should be approx. 310°F.  Preheat the matrix and master between the bearer bars on the lower platen for 2-3 minutes with a 1/8” gap from the top platen. (A = .187” bars, B= .312” bars).  Use release paper on top and bottom to avoid sticking to the platens.
3)  Slowly apply sufficient pressure so that the platens are tight against the bearer bars.  Cure for 5 minutes.
4)  Release pressure and remove from the platens.  Remove the master from the matrix.  Reinsert only the matrix using thinner bearer bars (A= .156” bars, B= .250” bars).  Use release paper on top and bottom to avoid sticking to the platens.
5)  Reapply pressure so the platens are tight against the bearer bars and cure for an additional 5 minutes.
