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.
