Purification Board Bonding
Purification board, also named cleanroom panel. Our cleanroom panel adhesive have many great features, like curable at room temperature/curable by heating, flexible operation time, strong weather resistance, easy to brush / easy to spray. Adhesive for cleanroom panel is top product in our company. Two component adhesive has higher bonding strength than single component adhesive.
Flatness standard: +0.1mm surface must be clean, oil-free, dry and water-free.
The supporting roles of the main agent (off-white) and curing agent (dark brown) are executed in corresponding proportions, such as 100:25, 100:20
After mixing the main agent and the curing agent, stir evenly quickly, and use a stirrer to repeatedly pick up the gel 3-5 times without silky brown liquid. The mixed glue will be used up within 20 minutes in summer and 35 minutes in winter
(1) 200-350 grams (materials with smooth interlayer: such as inorganic boards, foam boards, etc.)
(2) 300-500 grams for delivery (materials with interlayer porous: such as rock wool, honeycomb and other materials)
The glued board should be compounded within 5-8 minutes and pressurized within 40-60 minutes. The pressurization time is 4-6 hours in summer and 6-10 hours in winter. Before the pressure is relieved, the adhesive should be basically cured
Pressure requirement: 80-150kg/m², the pressure must be balanced.
The curing temperature is above 20℃, and it can be processed lightly after 24 hours, and can be processed deeply after 72 hours.
After the glue is used up every day, please clean it with dichloromethane, acetone, thinner and other solvents to avoid clogging of the glued teeth and affect the amount of glue and the uniformity of the glue.
