1 CORIAN JOINT ADHESIVE SYSTEM 8.1 CORIAN JOINT ADHESIVE SYSTEM As an integral part of its sheet and shape products, DuPont has developed a special adhesive. The DuPont Corian covers seam performance, not appearance. Corian Joint Adhesive comes in two parts, labeled Component A and Component B. All Corian Joint Adhesives are best used by date printed on the container Corian Joint Adhesive is produced in a range of specific colors to match with sheet and shape product. An exact color match cannot be guaranteed. The best looking seam will be obtained by careful seam preparation. See Sec.10.1 Long term storage of tubes should be done with the tube on its side. Also, always remove the mixer tip and replace the plugs if the adhesive will not be used within 8 1

2 CORIAN JOINT ADHESIVE SYSTEM Helpful Hints: Follow all instructions attached to the tubes. Pay particular attention to the safety and first aid details. Do not use adhesive that is past the use-by date. Protect adhesive from sunlight or extreme heat when transporting it to the job site. If adhesive is cold, allow to warm to room temperature before using. When using a manual dispenser, simulate the constant pressure of an air powered dispenser. Changes in pressure from pressurizing the cartridge will affect mixing and set time. To make adhesive flow faster, trim the mixer tip In warmer weather, mixing time may be reduced to maximize working time. CHPATER 8 2

3 BULK JOINT ADHESIVE SYSTEM 8.2 BULK JOINT ADHESIVE SYSTEM The Bulk Joint Adhesive is, as the name implies, DuPont Joint Adhesive packaged in bulk pack cartridges. Mixing instructions are as per, Cartridge Preparation. Storage conditions are listed below. Shelf life is also two years for the bulk. The bulk system is most effective where large volumes of glue are required. The bulk adhesive cartridge has a lot # or use-by date printed on the label. The key for the code is illustrated below: (indictes month of expiration 01-12) 2009 (indictes year of expiration) 1 Batch # (irrelevant in terms of use-by date) Long term storage of bulk cartridges should be such that the cartridge is horizontal. To prepare for the use of the bulk system, ensure that you have all the parts required to make it run properly: pneumatic bulk adhesive gun air hose pressure gauge air bottle (to make system portable) mixer tips bulk adhesive manual gun mixer tips 3

4 BULK JOINT ADHESIVE SYSTEM Cartridge Preparation: 1. Let cartridge stand on end for about 30 minutes before using. 2. Keeping cartridge upright, put into dispenser with small tube going in first. Plate directly under threaded area fits into slot on front of dispenser. Be sure cartridge fits into chamber completely. 3. Remove retainer cap. Slip off slotted washer and remove chamber plugs. Set aside plugs for later use. 4. Connect dispenser to air source and adjust pressure to about 25 PSIG. Dispenser regulator does not have a gauge. If air line does not have a gauge, turn regulator knob on gun counterclockwise until it stops. Then turn knob about three full revolutions clockwise to get 25 PSIG. 5. Keeping dispenser upright, hold end of cartridge over paper cup. While pointing dispenser away from anyone, pull trigger to allow any air trapped inside cartridge to escape and to fill chambers. Release trigger. If using manual dispenser, squeeze handle slowly until air is gone and chambers are full, then push tab on back of dispenser. 6. Put mixer tip in place. Mixer tip will only fit one way. Slip retainer nut over mixer tip, and lock it securely in place by giving a 1/4 turn clockwise. Mixer tip fit is very snug. Be sure it is in proper position before using, or leaking around tip may occur. 7. Adjust pressure to desired setting and run out a 4 (102 mm) bead of adhesive onto paper towel. Dispenser can be set down for about 5 minutes before a tip change is needed. If, after setting, flow begins slowly or adhesive looks thick, either run out adhesive until normal thickness is seen, or change tip. 8. To remove cartridge from air dispenser, press red button on back of hand grip until piston is completely retracted. Press small black button on underside of dispenser housing to dislodge cartridge. 9. To remove cartridge from manual dispenser, press lever behind handle and, retract the plunger manually. Press small black button on underside of dispenser housing to dislodge cartridge. 10. To store unused portions, first remove cartridge from dispenser, remove retainer cap and discard mixer tip. Replace plugs in end of cartridge, screw on retainer cap and secure plugs with slotted metal washer. 4

5 BULK JOINT ADHESIVE SYSTEM 50 ML CARTRIDGE Helpful Hints: If you have not used the entire cartridge and you wish to store for further use: Remove the tip and retaining nut, seal the cartridge with the plug, replace the retaining nut and replace slotted washer. The Bulk Joint Adhesive System is equivalent to 10 small tubes and is efficient and convenient. As the Bulk System is normally used for large glue jobs, it is important that all preparation is complete before gluing commences. The manual cartridge gun eliminates the need to use the air hose system, as it works by hand pressure only. For best operation, simulate the smooth continuous pressure of an air-operated dispenser ML CARTRIDGE DuPont offers a 50 ml. cartridge which like the bulk cartridge, has separate component chambers, requires a dispenser and a tip, and is re-sealable. One cartridge typically contains sufficient adhesive for two deck seams or one large kitchen sink. Storage conditions are as per previous adhesives. The expiration date is printed on the label as illustrated below: (indictes month of expiration 01-12) 2009 (indictes year of expiration) 1 Batch # (irrelevant in terms of use-by date) Cartridge Preparation and Use: STEPS TO COMPLETION: 1. Let cartridge stand on end for about 30 minutes. 2. Pointing cartridge up,, place cartridge in dispenser and close the black latch. The cartridge only fits in one way. 3. Remove cap and save. Install mixer tip and twist to lock in place. Mixer tip will only fit one way. Line up the raised point on mixer tip cap fits into the v - notch on cartridge. Spin the cap 1/4 of a turn clockwise to lock tip into place. 5

6 50 ML. CARTRIDGE DISPOSAL SILICONE 4. Squeeze dispenser handle slowly and dispense a bead about 1/8 wide and the length of the tip onto a paper towel or scrap piece of laminate. 5. Dispenser can be set down for about 5 minutes before a tip change is needed. If, after setting, flow begins slowly or adhesive looks thick, either run out adhesive until normal thickness is seen, or change tip and repeat Step To remove carridge from dispenser, press tab on back of dispenser and retract plunger and lift black latch. 7. To store unused adhesive, remove tip and replace cap. 8.4 ADHESIVE STORAGE To insure the longest shelf life, the adhesive should be stored in the dark, at room temperature (70 F., or 21 C.) or lower. In hot climates a refrigerator may be used but is not necessary. A dark, air-conditioned room will suffice. Both the 50 ml and 470 ml cartridges suould be stored on their sides Storing cartridges with tip in place may cause blockage making it very difficult to re-use remaining adhesive. Always remove the tip and replace the plug for storage. 8.5 ADHESIVE DISPOSAL It is important to dispose of joint adhesive in a manner which is consistant with our responsibility to the environment and which complies with all local, State and Federal regulations. To dispose of the adhesive, mix the left over components. This can be done manually without a mixer tip if desired. Wait until the reaction is complete then dispose of the reacted, solid adhesive. Caution: Adhesive may become very hot while reacting. Use heat resistant gloves if container holding reacting adhesive must be handled. 8.6 SILICONE When using silicone as your primary adhesive system, use a good-quality, mildew-resistant variety. If the silicone being used is for decorative purposes, a correct color match is recommended. This can be facilitated by using DuPont Surfaces Sealant for Corian and Zodiaq, DuPont produces a range of silicone colors to coordinate with sheet and shape color. The DuPont Surfaces Sealant has a use-by date listed on the tube. UPDATE8/07 6
