DAYAGEL MAGNUM is an especially high strength and robust detonator sensitive emulsion explosive. The product is gray in colors with a frim putty-like consistency.
DAYAGEL EXTRA is an especially high strength and robust detonator sensitive emulsion explosive. The product is gray in colors with a from putty-like consistency, packed with polyurethane wrapping material.
The post detonation fume characteristics of DAYAGEL EXTRA make the product well suited to both underground and surface blasting applications but as with all explosives operators should ensure that adequate ventilation is provided prior to re-entry to the blast site.
While sensitive to initiation by a No. 8 detonator, DAYAGEL EXTRA has a very low mechanical impact sensitivity. This impact insensitivity criterion is a very important safety feature.
If exposed to fire, DAYAGEL EXTRA will self extinguish unless a vigorous external source of heat is applied. Whilst DAYAGEL EXTRA does not burn easily, it should be kept clear of flame or excessive heat.
If DAYAGEL EXTRA remnants are to be destroyed by burning, advice on the correct method should be sought from DAHANA Engineering Center located at DAHANA offices, or from the local explosives statutory authority.
DAYAGEL EXTRA is a water resistant packaged explosive designed to deliver high energy in both priming applications and as a relatively high density column explosives in mining, quarrying and general blasting work.
RECOMMENDATION FOR USE
Blast Hole Depth
Suitable for use to 3-50 meters depth of blast hole.
DAYAGEL EXTRA has been designed as a detonator sensitive explosives and will deliver maximum energy and efficiency when initiated by a detonator of No. 8 or greater strength.
Watergels or nitroglycerine based explosives are NOT recommended as primer for DAYAGEL emulsions due to their relatively low velocity of detonation.
Detonating Cord Effects
While 10 g/m detonating cords may be used while as up lines or down lines to initiate DAYAGEL EXTRA.
Detonating cords of lower charge mass than 10 g/m are not recommended for us with DAYAGEL EXTRA. If in doubt consult DAHANA’s Explosive Technical Specialist.
