Description
Yamakin’s new primers have been designed using the unique technology developed by our professional organic materials team.
For Simple and Speedy Working from Metals to Zirconia.
Multi Primer LIQUID
This primer is a surface treatment liquid for frameworks made of precious metals, non-precious metals, and zirconia to bond resin materials.
Table: Areas Suitable for Usage
The light-curing time given in our instruction manuals differs depending on the light curing machine.
Please check using the above light-curing time chart.
Basic Layering Step
①Surface Treatment of Frameworks
②Additional Layering Step
In thecase of application of resin on a cast metal framework
» Metals for frameworks: Au alloy, Au-Ag-Pd alloy, Ti, Ti alloy, Ni-Cr alloy, Co-Cr alloy
Using Multi Primer LIQUID
Sand-blast (about 0.2~0.25Mpa) the surface using alumina powder (about 50µm); then use steam cleaner or ultrasonic cleaner to wash. Then dry.
Apply Multi Primer LIQUID with a round brush thinly and leave it for about 60 sec. to dry.
Combination with Luna-Wing or TWiNY
Curing time should be as given in the instruction manual for the material.
Apply Invisible Opaque with a flat brush to cover the retention beads, filling the gaps between beads and light cure.
Apply Opaque with a flat brush and light cure. In cases where metal color is visible, repeat this step until the color is concealed.
Body application and light curing.
Using Multi Primer PASTE
Sand-blast (about 0.2~0.25Mpa) the surface using alumina powder (about 50µm); then use steam cleaner or ultrasonic cleaner to wash. Then dry.
Apply Multi Primer PASTE with a flat brush to cover the retention beads, filling the gaps between beads. Leave undisturbed for about 120 sec. and light cure for about 90 sec.
While Multi Primer PASTE is left undisturbed for about 120 sec., a reaction bonding components and metal surface proceeds, and strong bonding strength is obtained by the process.

Curing time should be as given in the instruction manual for the material.
Apply Opaque with a flat brush and light cure. In cases where metal color is visible, repeat this step until the color is concealed.
Body application and light curing.
In the case of application of resin on a CAD/CAM metal framework
» Metals for CAD/CAM framesworks: Ti, Ti alloy, Co-Cr Alloy
Using Multi Primer LIQUID
Since retention beads cannot be used, Sand-blast (about 0.2~0.25Mpa) the surface using alumina powder (about 50µm); then use steam cleaner or ultrasonic cleaner to wash. Then dry.
Apply Multi Primer LIQUID with a round brush thinly and leave it for about 60 sec. to dry.

Body application and light curing.
In the case of application of resin on a CAD/CAM Zirconia
» It is recommended that the surface should be made uneven in a stepped manner, with a difference in levels of about 0.1mm.
Using Multi Primer LIQUID
Sand-blast (about 0.2~ 0.25Mpa) the surface using alumina powder (about 50µm). This step is required in case where composite resin is applied. Immediately after sand-blasting, use steam cleaner or ultrasonic cleaner to wash. Then dry.
Caution: In cases where composite resin is applied on a zirconia framework, do not heat-treat after sand-blasting.
Apply Multi Primer LIQUID thinly immediately after washing and drying, then leave about 60 seconds to dry.

Multi Primer REPAIR LIQUID ONE
Grind resin surface with a carborundum or diamond point and make the surface rough.
Apply Multi Primer REPAIR LIQUID ONE thinly on a ground surface and leave undisturbed for about 120 sec. then light cure in cases where surface is slippery.
Combination with Luna-Wing or TWiNY
Curing time should be as given in the instruction manual for the material.
After resin application, apply Resin Air Barrier on the additional layering area, then light cure as a final curing. Again correct the shape to finish.
